• Build automation that delivers value, not just for its own sake

Required profile

• Clear, professional written and spoken English
• Self-starter who can work on a small, international team and during US Eastern business hours

Required skills

• Real test-management tooling experience (Qase, TestRail, Zephyr or Xray)
• Cross-layer testing: APIs, backend, databases, web and mobile

The process includes a pre-screening, a 45-minute video interview with the People & Culture Manager, a 30-minute Claude Code AI assessment, and a meeting with the Engineering Manager and VP of Technology.
