About The Position

We are seeking a Test Engineer to join our team. In this role, you will be responsible for writing test plans, building custom fixtures, and analyzing data to draw conclusions. Your work will span from early characterization through production validation. You will work alongside a team of test engineers and technicians, making engineering decisions and taking ownership of your work. This role requires a hands-on approach, with experience in both lab and machine shop environments.

As a startup, we foster a collaborative environment where the best ideas prevail. We value individuals who take initiative, communicate proactively about issues, and contribute to raising the overall standard of work.
