What we offer

As an early organization we offer a base salary with a large stake in the future upside of our effort. Our leadership has successfully started and sold previous startups, and although we have chosen an approach that puts our values first, and profit second, we still expect a good future financial outcome as well. We offer a creative, highly participatory environment without the classical top-down hierarchy. We value that each candidate brings their own unique mix of skills and experience.

We are a remote team and your location is not as important as your timezone. We operate across the European and American time zones. We believe your life outside your professional commitments should be enjoyed, and time to rejuvenate is critical to thriving. That’s why we work flexibly during the month. You commit your time for a specific number of hours during a month and you can work during the times that are most productive for you.

We have several team meetings to learn from each other and see the whole product, but also to grow ourselves by giving and receiving feedback but also to give and receive appreciation.

If you checkmark at least 5 of the items and you feel a connection to what we do and how we do it, do apply!

We really appreciate a cover letter when you apply for the job. We receive a lot of applications so the cover letter can make the difference!
