Shape the future: Build something that matters and learn about sustainability's impact on business.

Flexibility and Freedom:
We do not believe in micro-managing. Your responsibilities and tasks are your own and we will support you to achieve these. We won’t breathe down your neck! Take your time to shape your ideas and thoughts and work the way you like.

Ownership and Empowerment:
We empower you to own your ideas from conception to delivery and we support each other’s professional and personal development, e.g. through regular 1:1 meetings.

We encourage flexibility in work hours and design policies to allow you to spend maximum time with your family or personal development (e.g. sabbaticals, thesis projects). This is being lived by the founding team.

If you are interested in joining us, send us examples of your work (e.g., GitHub repo), your letter of motivation, and your CV. The next steps will be a short technical interview with a member of our engineering team.
