Build automatic test system

Use CAN tools

Design test cases

Perform fault injection

Analyze root causes

Execute test cases

We are looking for:

We need people with no-nonsense attitudes and robust personalities, that can cope with the chaotic start-up environment.

You don't need to know everything. What matters most is your curiosity, motivation, and willingness to learn. You will be encouraged to make decisions and take responsibility for failures as well as successes.

What do we offer:

We are a small team of highly experienced people. We know what we want, we have a very in-formal and straight forward culture, where we build solutions on facts rather than feelings.

From a cultural perspective we are diverse and we strive to make the company even more diverse in gender, age, culture etc. We believe it stimulates a more creative and interesting work environment.

You will help develop technologies that support electrification, renewable energy, and the global transition toward a more sustainable future.

We are currently located at the DTU Science park in Lyngby, Denmark with many other start-ups; a dynamic environment with canteen, café, many exciting events and rather close to Copenhagen. We will continue to be in a similar environment, but we are exploring options closer to Copenhagen and will most likely be moving in the next couple of months.

Interested?

If you've read this far, there's a good chance we should talk. We'd love to meet you.
