Mechanical Engineering Job Search

When looking for a job, ask yourself three questions

  • What do I want to work in?
  • Where do I want to work?
  • Which company is most suited to my future career?

Do a simple search on LinkedIn for mechanical engineering jobs and you’ll see the diverse fields in which a mechanical engineer can work, such as product design, manufacturing, HVAC maintenance, piping systems design, etc… Since there are so many different types of jobs, I started evaluating my preferences. There are two fields that I’m really keen on, first is automation services that will enhance my control and system modelling skills. I also want to get more practice with logic programming and instrumentation coding. The second field is power systems regulation and management, particularly in the renewable energy sector, despite it being more related to electrical engineering. I also like to work on CAD/CAM, skills that are mostly related to product design, validation, and development.

Company size, culture and established locations are also very important to me. Jobs available in the United States and Europe intrigue me, but my top locations are Seattle, New York, and Toronto. In terms of company size, I prefer a global company with job openings everywhere in the world. A globalized company will also allow for more internal mobility, in case I want to switch jobs across departments. A dynamic work environment and a motivated and cooperative team are what I look for in company culture. All these contribute to which jobs I apply to.

A couple companies are on my radar. Siemens is a German conglomerate company with heavy emphasis on automation. Some of their notable divisions are industrial automation, energy automation, building technologies, and drive technology. They have major branch offices in Germany, US and China. They have a prominent division called Gamesa Renewable Energy that have provided wind turbines to offshore and onshore wind farms in the UK and Denmark. An exciting recent development that Siemens Canada acquired is designing the power grid for New Brunswick and Nova Scotia, formally called the Smart Grid Atlantic Project. This project aims to analyzes challenges and opportunities involved in integrating renewables and improving the grid’s reliability and efficiency. I hope that by landing a job with Siemens Canada that I can transition to Siemens in US and participate in their engineering training programs. Another company I would be excited to work for is General Electric. GE is along the same lines as Siemens, a global product-focused company, except they started in the States. In terms of innovation, I think Siemens is a bit more sustainability centered.

There are also lots of regional and local companies I could apply to, not to mention the consulting field is another huge area for engineers to work in. I will explore these in the next blog.

Talk to you soon!

 

 

Classes at ETH vs UBC

Portraits of famous scientists and engineers greet you from the west wall of ETH. The stone causeways and massive wood doors instil a sense of magnitude and significance to the university. Their mechanical engineering courses follow suit. Never have I studied so hard for such mediocre grades.

Part of the challenge came from class format. There is a distinct lack of hand-holding in these courses, which is a good thing. Engineering students at ETH learn very early on to take full control of their own schooling, as all course material is available early on in the semester and most tutorials or quizzes are non-mandatory.  Four of my five course grades were entirely dependent on final exam performance. (this seems less common in other engineering departments).

Think that’s nuts? Many of the exams were formatted as a 20-25 minute oral interview, one on one across from a stoic witness and the professor that remembers every nap you took in class. It takes one forgotten concept or wrong answer to drop a letter grade. Questions ramp up in difficulty and any time spent thinking of responses means less time to show A-grade knowledge in the latter material. This explains why I saw students studying full time all summer for the 7-8 courses (some Spring semester exams happen in August). There’s a re-examination option for oral exams but mobility students (you) don’t get that luxury.

Aside from these terrifying details, the course experience is fantastic — if you’re prepared to put in the work. Many professors are current leaders in their fields, showing off new material from the cutting-edge of applied science. Software exercises utilized modern and industry-relevant applications (though I had a couple concepts explained succinctly via FORTRAN code).

FYI, the exchange structure in 2018 included a flat-rate fee from UBC and waived fees at ETH so you could take as many courses as you were eligible for. Use this to your advantage. Many engineers took things like Artificial Intelligence, Machine Learning, and other out of scope topics for the sake of interest. Your exam registration happens later in the semester and you had no obligation to take the exam for these courses (i.e. to get recognition of them on your transcript). This may change down the road so just check these rules before your trip.

Here is the course list that I took with a brief review of each:

151-0361-00 An Introduction to the Finite-Element Method

The introduction lecture was comically-terrifying, as the professor skimmed through each course topic with key mathematical concepts. So much material was packed into the two hour lecture that I honestly thought I was expected to read half the textbook before classes begun. Speaking of which, it took a month of review and Googling to figure out the first 24 pages, which introduced the underlying principles and derivations.

I think this course is so important to modern day mechanical design. While you may not encounter FEM analysis in every job, the concepts you learn through the course can be applied to a variety of complex engineering problems. Computation time is expensive in professional settings, so knowing how to optimize your simulations for both time and accuracy improves your value to any company.

Despite the niche topic, I think this course made the most impact during my time at ETH.

151-0548-00 Manufacturing of Polymer Composites

The professor for this course regularly consults for the big aerospace and automotive companies while acting as head of the composites department. The 400-page textbook he wrote is a litany of relevant information in the analysis and production of various composites. This course felt like the final boss fight for mechanical engineering students, integrating topics from literally every fundamental course I’ve taken at UBC, as well as some material from my previous life science degree (brush up on your organic chemistry folks).

The material is incredibly useful for those getting into high-performance industries but this was also the toughest exam I took at ETH – an open-book, two-hour written monstrosity with 35 pages of questions and background information. I don’t think anyone finished writing it in the time given. However, the textbook is so good that I will be referencing it for all my future carbon projects (looking at you, Formula UBC).

151-0316-00 Methods in the Innovation Process

I took this course to see how design differed in Europe. The creativity components were a welcome change of pace from the theory overload of my other classes. As expected, a number of design methods and concepts carried over from our excellent offerings at UBC. The course was structured as a miniature design project; each team was expected to complete rounds of proposals and prototypes while exercising different methods of decision-making. I learned that ETH doesn’t require a major design course every year in their MECH program, but a number of these smaller project courses exist as options. It certainly seems ETH weighs undergrad towards the mathematics and fundamentals while UBC perhaps leans the other way.

The course instructors are professionals in their respective fields so the networking and coffee breaks are very worthwhile; consider the experience an opportunity to flex your design muscles and work with different engineering backgrounds. It’s a great way to meet local students too, as you spend many hours together during each workshop.

151-0280-00 Advanced Techniques for the Risk Analysis of Technical Systems

A refresher on stochastics, with emphasis on characterizing complex networks like transportation and energy grids. However, the material carries over to any system with multiple, independent parts. This is highly useful material for design and production engineering. I sometimes wish we were provided a stronger stats background at UBC, but I suppose fitting every “nice-to-have” into the program would keep us there forever.

151-0358-00 Structural Optimization

This course is an excellent complement to FEM (and conveniently, taught by the same professor during my stay). While you learn to solve particular load cases in FEM, Optimization teaches you how to automate the design process to find best-fit solutions. You learn enough in this course to write basic optimization scripts for small scale optimization problems (minimum mass design with target stiffness, for example). More importantly, the courses teach you what is going on behind the scenes in ANSYS or Inspire, so that you know exactly which configurations and how to interpret your results.

Engineering Mentoring: Tour of Corvus Energy

As I mentioned in the previous blog, my mentor is a senior engineer at Corvus Energy. This Monday, he showed me and another engineering mentee around their office and factory. Corvus Energy is a company that makes energy storage solutions, with their most novel product being arrays of battery banks for marine applications, from yachts to ferries. Their ingenuity comes from the robustness, reliability and modular ability of their product. Moreover, it has the flexibility meet different demands of various sizes of marine vessels, from small yachts to large ferries like Scandlines M/V Berlin, a Scandinavian fleet that travels between different ports of Denmark, Germany and Sweden. Seeing a Canadian technology emerge and be competitive in the global market was really impressive, especially when you consider the context. Scandinavia contains some of the world’s most sustainable countries that have made strides at implementing sustainable technology. Yet, it’s a Canadian company that has helped them make their ferries hybrid. Following this trend, I’m hoping that Metro Vancouver, with it’s Renewable City Action plan, will become one of Corvus Energy’s strong corporate client and partner down the road.

The tour gave me such an inspiration. The space was very bright, colorful, and full of energy. When I arrived at the office building, I could immediate tell it was an engineering work space. A section of the building was dedicated to testing and product improvement, with prototypes and instrumentation equipment laid out on work benches. What I also loved about the space was the openness. There was no barrier, no cubicle, allowing the engineers to exchange ideas, and to collaborate.

At the factory, my mentor showed us their product assembly line. On the roller table, there were numerous unfinished products, each representing a stage in the assembly process. Not only were the battery units assembled in the factory, they also underwent stringent testing and validation at every stage. A number of quality control gates were especially designed to ensure the final product will have zero defects before they are deconstructed and shipped off to clients. The cool thing about the factory was how it was expanding. Since Corvus Energy is a growing company, it required more assembly and storage space to accommodate new products. My mentor showed us how they had to build a second level in the warehouse and a new assembly line for new generation product.

With this sort of clean and organized work environment, both in the office and the factory, Corvus Energy employees can truly exert their full potential. My mentor also expressed the importance of connecting the office and factory so engineers can work more cohesively with the technicians on the floor. In my future work space, I would like to work not only with the products I design, but more importantly, establish a strong relationship with the people whose decisions I make affect.

If you want to check out Corvus Energy, here’s their website: https://corvusenergy.com. They have internships and Co-op positions available, so don’t be afraid to reach out!

Tune-in next time for more updates.

 

Second steps in Switzerland: Living Expenses, Establishing Routines

Living Expenses

Spend time shopping around for necessities: groceries, toiletries, etc can vary wildly in price from different shops. The quality spectrum seems much broader than in Canada, with organic (“Bio”), import, and many other options. Fortunately, I’ve found that most budget brands still tend to be high quality, often times better than the Canadian equivalent. Local dairy products and in-season produce are all excellent.

If you haven’t developed the habit yet, it’d be a good time to track your expenses and learn where your money goes every month. It’s tough to incorporate into daily routines as a stressed student, but ETH courses seem to happen in 2-3 hour blocks, minimizing time spent commuting to multiple hour-long sessions a week. Set up your own spreadsheet or use software like Mint or YNAB. You’ll be shocked at how quickly those frappes and/or gipfelis add up. I never budgeted during my first degree and by the end of first year I discovered $500 evaporated into bubble tea…

A good metric is to imagine the cost of a trip or experience you really enjoy, whether that’s travel, gastronomy, etc. Travel is absurdly affordable here, so it’s easier to put time into making coffee every morning when you’re saving 0.5 “Transit to Italy” every week.

ETH recommends setting aside 1750 CHF per month as typical cost of living, including rent, bills, etc. If you secure WOKO housing, this figure may be quite high. Here are a few ranges I saw during my exchange for monthly expenses:

    • 450 – 600 CHF rent
    • 65 – 100 CHF Swiss healthcare
    • 70 – 90 CHF monthly transit pass
    • 10 – 40 CHF phone plan
    • 150 – 400 CHF food (yikes)
    • 100 – 500 CHF leisure
    • 100 – 300 CHF irregular expenses (new clothes, one-time fees, whatever)

If you figure out batch-cooking at home, cycle or walk most places to save the monthly transit pass, and plan your weekend trips in advance (Check out SBB Supersaver tickets) you can get away with 1000 to 1200 CHF per month in total expenses. Most students seemed to be in the range of 1200 to 1500.

Fun fact: the last survey indicated a median monthly salary of 7500 CHF per month for technical positions in Switzerland.

With regards to leisure and travel, that 100-500 range depends a lot on transportation options. Switzerland’s domestic train system offers a bunch of Student perks to cut their relatively-high ticket prices. I took advantage of two key discounts during local travel while other students added a third:

  1. Halbtax (Half-fare) Subscription
  2. Supersaver tickets
  3. Gleissieben (Gate Seven) Subscription

1 and 3 are both upfront payments for 12 months (with a possible 6 month refund point to get some money back I believe). The halbtax offers half price 2nd-class fares on almost every train any time of the day. Gleisseiben provides free travel to students (<25 years old) between 19:00 and 5:00. Almost everyone bought the halbtax, but do the math to see if Gleissieben would be worth it. I found most students traveled in groups and if only a few people had gleissieben they were usually outvoted regarding travel times.

Supersaver tickets are discounts for specific trains at specific times that you can find listed on the sbb website when you’re browsing potential trips. While normal train tickets allow travel on any line heading in your direction within a specific period of time, the Supersaver tickets limit you to one particular departure. These are nonrefundable so make sure you’re not late if you take advantage of this. Supersaver can be stacked with Halbtax which can be super useful, especially as they tend to be off-hour departure times which students can usually take advantage of.

I know it sounds complicated at first. It stays complicated once you get used to it.

Establishing Routines

After sorting out your favourite spots, it’s important to find a groove early-on. Jet lag, new people, weird class schedules, and the plethora of student activities/events will be super distracting. It was March by the time I had cracked open my course PDFs and printed them like all the local students had already done (P.S. your ETH card comes preloaded with more than enough print credit for you to print these all out on campus!). This groove can (and should) include adventuring time. Wander the dense city streets or hundreds of nature trails. Take the train to an unfamiliar place. It’s easy to get lost in Switzerland, but you’re always close to a railway, bus, or restaurant and they’ve never even heard of ghettos.

While it might feel like ETH classes provide a lot more free time than anticipated, fit some studying/reading of the lecture material in every week. It’s tough to do if you have classes with no weekly assignments and new travel propositions every weekend. Find an hour or two every day if possible, as the material stacks up very quickly. For example, my Finite Element class covered a month of material by North American standards within the first two lectures. Oral exam preparation is a different beast to written tests; more on this in later posts.

Set up calendar reminders or e-banking payments for monthly expenses. Many students forget about rent, phone bills, etc as they get used to their new bank accounts. New habits might include transferring funds from Canada to Switzerland, or converting Euros before trips abroad. You may have to make payments in person at the local post office so account for processing times. Late fees aren’t cheap here.

First Steps 2 – Electric Boogaloo: Student Visa, Residence Permit, Health Insurance, Banking

First Steps 2 – Electric Boogaloo: Visa, Residence Permit, Health Insurance, Bank Account

Part of the initial Mobility application to ETH includes the processing of a Visa Authorization form, which the Swiss Consulate needs to issue your official student visa. However, the fee for this authorization form wasn’t required until you get to ETH Zurich. It’s payable at the school, so don’t forget to pay this; supposedly many students do.

Residence Permit is listed in the ETH Zurich pre-trip documents package as obtainable after a certain number of weeks in Zurich. Try to beat the rush by getting your student documents as soon as possible from ETH. Importantly, the city will want your Matriculation paperwork that comes in this document package. Then, find your local city office and they can process the permit as long as you have everything exactly as described in the permit requirements list. Passport sized photos are used for a number of ID cards during your stay (off the top of my head, residence permit, transit pass, Erasmus Student Network card, International Driver’s License) and you can get them done at many automated photo booths around the city. Don’t be afraid to get the strip of 4 or 5 photos, as you’ll definitely make use of them.

Fun fact: In 2018, Zurich still had two operational automated dark-room photo booths that performed the same functions electromechanically as the modern digital ones — super cool to operate as aspiring mechanical engineers. I met the gentleman responsible for refilling the exposing chemicals and had a lovely chat. Try to find them on Google Maps if they’re still around!

Non-EU students pay a higher fee for the Residence Permit so make sure to bring a couple hundred Francs or set up a local bank account quickly.

Speaking of bank accounts, make sure to open one as soon as possible (if you require it). Some banks have been known to deny students if they are staying for less than 3-4 months. Single semester exchanges just barely satisfy this requirement! You’ll end up saving a bit of money going this route as the accounts are typically free for students and you avoid the fees that local Canadian credit and debit cards typically charge for usage in foreign currencies. Reward programs exist too that netted me about 100 francs by the end of my exchange. In addition, reputable, online services exist to transfer currencies between your CAD and Swiss accounts without having to go to pricy local currency places. Some of these services even have bright green international debit cards you can use to get cash from nearly any European ATM. Look for these 😉

German Classes

UZH, a sister university to ETH, offers an intensive German class that occurs before the start of semester and has limited seating. The language center or “Sprachenzentrum” will post the start and registration dates fairly early. I’d recommend doing the intensive course if you can; not only is it better timing as you’ll have a beginner’s grasp of German before school starts, but you’ll remember more of it since you’re immersed full time for two weeks. Semester courses only happen once or twice a week, with teachers reporting most students forget more of the beginning material by the middle or end of the semester.

Note: This will seem obvious to some, but dates are listed as DD.MM.YYYY which may be different than you’re used to; double check registration time zones and dates! People were still booking incorrect train tickets and accommodations halfway through semester because of these minor differences.

The intensive German class is also a great way to meet people outside of whichever residence you’re in. The class is typically other exchange students and you spend every day with them, so you’ll have plenty of opportunity to connect with people for alpine trips and other adventures before the semester really gets going. The teachers included a surprise session on tips and tricks around Switzerland. There were quite a few useful reminders in there, including various student discounts to take advantage of outside campus, travel discounts, and services such as bike and car shares that I wouldn’t have known about otherwise. My class ended with a day trip to the local zoo and final “apero” with the teachers. Apero is another great opportunity to meet local and international students alike; don’t be afraid to exchange contact info after a short exchange. Sprachenzentrum supports all ETH and UZH programs so you may not get another chance!
