To build world-class products, we assemble world-class talent. Supported by our fully remote work arrangement, our team spans Eastern Europe, the Middle East, India, and Southeast Asia, allowing you to work with brilliant engineers and builders from around the globe from wherever you are.

  • Lead technical investigations, root cause analysis, and continuous improvements for large-scale production systems.
  • Collaborate with Product, Platform, Infrastructure, Security, and Business teams to deliver reliable and scalable solutions.
  • Stay hands-on with implementation when necessary, particularly for critical architectural components and complex technical problems.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
