Job Description

As our next full-time backend engineer, you'll help us build a securities API for financial institutions, the first such API in Europe. Your goal is to take ownership of designing, developing and maintaining our microservice architecture (written in Go).

  • We invest in you. From access to a personal coach, development budget and plenty of opportunities to grow in your role.
  • We take hiring seriously with a strong focus on keeping a high bar when interviewing (equally important is that we also hire decent people who are passionate about their craft and helping up achieve our shared mission).
  • While we're not quite fully-remote, we are committed to being a flexible employer as we understand you don't have to be in the office to do your best work.
  • We live a culture of empowerment, trust (that we hire the best people and get out of their way) and openness (there's a greater advantage in sharing information than keeping it to ourselves).
  • We ensure we take time to have fun as a team. We're looking forward to having more time in-person again once this becomes possible again.
