  • Comfortable working in an Agile development environment
  • Strong problem-solving and debugging skills, with a sharp eye for performance tuning
  • English proficiency at B2 (Upper Intermediate) level or above, written and verbal, with the ability to explain technical concepts clearly

  • Exposure to CI/CD pipelines and Infrastructure as Code (Terraform)
  • Familiarity with containerization and orchestration (Docker, Kubernetes)
  • Previous experience in startups or fast-paced environments
  • A growth mindset, team-first attitude, and passion for quality, security, and automation

Compensation: €2,000 – €2,650/month net, depending on experience and seniority level.

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.
