Explore. Dream. Discover. Get curious.
Want to play your part in the future of clean mobility?
Are you currently pursuing either a Master's degree in Science, (Applied) Physics or Engineering? Are you the person that loves to look at the details and what makes up the details of how things work? Then have a look!

Full-time · Helmond / Remote

Summary
Where: The Automotive Campus in Helmond and from the comfort of your own home
Domain: Material and Process Engineering 
Degree: Master's degree

Which team will you become part of?
At Lightyear, our Engineering Team is divided into different domains which vary from Aerodynamics up to Software and everything in between. Essentially, we have all the expertises in-house to build Lightyear One. While you become part of the Material and Processes Domain within Engineering, you’ll be surrounded by engineers coming from different backgrounds. Some of them were part of a student team (such as Solar Teams, Formula Student), some come from the automotive industry and some are equipped with a solid high-tech background.

In order to increase the technology readiness level (TRL) of Lightyear’s powertrain systems, there is a need for accurate modeling techniques that predict how performance might decay over time in order to provide recommendations to mitigate risks of unexpected failures.

Due to the increasing focus on efficiency, the adoption of wide band gap semiconductors (such as SiC and GaN) for EV traction inverters are increasing. With these next generation semiconductors come new challenges such as higher power densities and motor - traction inverter integration. One of these new developments is a MOSFET package designed for direct attachment to a heat sink using a sintered silver layer. This connection will be exposed to a wide range of temperatures (both environmental and self-induced) and vibrations.

The internship will contribute to the internal team working on modeling and characterization of sintered connections in the Research department. At Lightyear, every individual left behind their safe havens to achieve our mission. So, a passionate and energetic team is guaranteed.

Your personal mission
The aim of this internship is to improve predictive modeling techniques for the mechanical reliability and durability of the sintered bond layers. Earlier work has focused on analytical and numerical modeling of sintered bond layers. As a follow-up to this earlier work, the proposed internship would focus on correlating the pre-developed modeling techniques with testing/test results of sintered bond layers and thereby determining, validating, and improving the accuracy of these modeling techniques. Ideally, processing parameter dependency should be taken into account as well. In addition, planning, designing, and conducting tests would be part of this internship.

Requirements in order to achieve your personal mission
Be aware, being an intern at Lightyear isn’t just an internship. You’ll be approached as an actual engineer and that requires some skills and being able to take responsibility. Especially given the fact that you’ll join a scale-up where little is set in stone. Therefore, it’s key that you can relate to the following things:

  • You’ve proven that you’re strong both theoretically and pragmatic. For instance, you’ve been part of a student team (such as Hyperloop, Solar team, Robocup), did other extracurricular activities, worked in a start-up, you did an outstanding internship or you do sports at a semi-professional level. At Lightyear, we highly value this.

  • You’re entrepreneurial. Really! You’re able to swim when we drop you into the ocean and you’re able to speak your mind.
  • You are able to work autonomously and in a team.
  • Currently working towards your Master degree, ideally with a strong emphasis on Solid Mechanics or Electro-mechanics.

  • At the stage of graduation internship or thesis.
  • Preferred start date: 09-2022.
  • Duration of internship: min. 6 months.
  • Fluent in English.
  • (Some) prior knowledge of coding in Matlab, Python and/or equivalent tools.
  • Prior experience with FEA tools like Ansys or Comsol is a plus.
  • You strongly identify yourself with our bigger mission: clean mobility for everyone.

What you bring along as a talented intern

  • Critical thinker/mindset
  • Assertive work attitude / Self-starter
  • Team player
  • Structured way of working
  • Open communicator

What do we offer
In addition to a challenging (graduation) internship you also have the opportunity to work for a company with a real, honest and ambitious mission. In this way you have the opportunity to make a huge impact on the future of mobility! Next to this, we also offer:

  • A high degree of freedom and independence during your internship.
  • A multidisciplinary team of highly motivated and talented people you can learn from.
  • A certain internship allowance depending on your educational level.
  • Monthly meet ups with other interns to have snacks and drinks while meeting other like minded individuals.
  • Monthly engineering peer learning sessions where you learn from other interns on what they do and how they solved it.
  • In addition to a dynamic work environment, there is time for relaxation during our Friday afternoon drinks!
