Responsibilities

• Build Java backend services powering TeamViewer Tia for end users, from feature APIs to integration points with the wider platform.

• Regular use of AI coding agents, combined with a critical review mindset and accountability for the correctness, security, and maintainability of delivered solutions.

• Ability to design and implement automated testing strategies robust enough to validate high volumes of generated code and prevent regressions.

• Strong understanding of common AI system failure modes, including hallucinations, context degradation, prompt injection, non-determinism, and silent regressions, along with effective mitigation approaches.
