About The Position

Computer Graphic
Hi! 👋

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

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

We transform businesses by delivering sustainable, API-first (while not always easy to achieve, it’s worthwhile), 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. 🔥

One of the most essential things at Mirumee is that our culture is centered around people and open source. We are active members of the open source community, creating 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 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), Paweł (Backend&Saleor) and Wojciech (Product&Frontend). You will work directly with the CEO, COO and other department leaders also. 🦹

We try to keep our recruitment process brief, but some steps need to happen:
1. Screening with one of our Recruiters.
2. Interview with Paweł (mentioned above) and Michał (COO).
3. Meeting the whole Principals team.
4. Offer meeting.

  • The possibility of taking part in international events, especially if being a speaker sounds like a marvelous adventure to you!
  • 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).
  • We give you 5 extra days for health recovery (b2b) and the basics to take care prophylactically - private healthcare that works (Signal Iduna), mental health support (Wellbee) & sports card (Multisport Plus) for free
