Position Summary

  • Minimum 15 years of software engineering experience, including experience leading technical design for distributed systems and integrations.
  • Strong understanding of system design principles, integration patterns (REST, event-driven), and API lifecycle management.
  • Experience with modern delivery practices (Agile/Scrum, CI/CD) and release management in
  • production environments.
  • Proven ability to troubleshoot complex production issues using logs, metrics, traces, and structured RCA approaches.
  • Strong communication skills to lead technical discussions with stakeholders across engineering, product, QA, DevOps, and vendors.

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.
