Job description

Online interview

Hi! 馃憢

We are a Python and JS/TS software house that specializes in developing聽unique products聽and聽composable systems.

Founded in 2009, starting with a few people in a tiny office, but with聽huge ambition and dreams聽to do something meaningful in the software industry, not only commercially.

We transform businesses by delivering聽sustainable, API-first聽(while not always easy to achieve, it鈥檚 worthwhile),聽efficient and modern solutions. We empower businesses of all sizes, from high-volume online retailers to disruptive innovators mentioned on the Forbes Next Billion Dollar Startups list. 馃敟

One of the most essential things at Mirumee is that our聽culture聽is centered around people and open source. We are active members of the open source community, creating聽Ariadne, a schema-first GraphQL server library for Python, eagerly sharing our knowledge as mentors and speakers at events across the globe and creating the biggest GraphQL Meetup in Poland and beyond.

We care about technical excellence, open communication, and treating each other with respect聽as equal human beings. The Principal Developers team is extremely important- it's where role models come from. Our heroes are Anton (QA), Jan (Frontend), Pawe艂 (Backend&Saleor) and Wojciech (Product&Frontend).

You will work directly with the CEO, COO and other department leaders also.聽馃

  • Work wherever, the way you want: we don't care if you start at 6 or 10 am and give you a choice between a beautiful office, home office spot, or a combination of both! Although we require visiting our HQ at least once a quarter (see relationships point).
