• Improve validation of shared engine changes against real game integrations, reducing manual effort and increasing confidence.
• Create and maintain tooling, infrastructure and test surfaces for engine and horizontal teams.
• Partner with client, server and live‑ops teams to make systems more testable and reduce downstream surprises.
• Apply AI‑assisted workflows to validation, automation and test generation with clear guardrails.

Required profile

• Strong professional experience in modern C++.
• Engine/runtime development experience with debugging across iOS, Android, macOS or Windows.
• Deep understanding of testing and validation strategies, from unit to end‑to‑end testing.
