Senior QA Test Automation Engineer

About the role

You will own the end-to-end test automation strategy for our Unity-based mobile titles on iOS and Android, turning quality requirements into robust technical solutions. This role requires you to architect frameworks that are scalable, maintainable, and aligned with industry best practices across the product lifecycle. You will define and drive the automation roadmap in collaboration with Games QA, Game Developers, and SDK/Engine partners to ensure quality is built in from the start. A pragmatic mindset is essential, as you will balance automation delivery with the flexibility to perform manual testing when release timelines or complex issues demand it. You will act as a quality advocate, shaping standards and influencing engineering decisions to reduce risk and increase deployment confidence. Your work will directly protect release stability by integrating automated checks into CI/CD workflows, enabling faster feedback and safer delivery. You will mentor and collaborate with cross-functional teams, translating product goals into executable test scenarios that validate gameplay, integrations, and backend services. Ultimately, this position is about building a durable automation foundation that accelerates development while maintaining the highest level of product quality.
