Design and build automation tooling and frameworks for AI/LLM‑driven systems, including prompt flows, agent orchestration, and tool integrations.

Develop and maintain evaluation frameworks (evals) to measure response quality, accuracy, and hallucination rates.

Drive automation coverage (80%+ for critical AI workflows) using deterministic + probabilistic validation approaches.

Integrate AI quality checks into CI/CD pipelines with fast feedback cycles ( Build tooling for LLM observability and debugging, including prompt tracing and response analysis.

Partner with Applied AI teams on prompt engineering, model selection, and evaluation strategies.

Design and execute performance and load tests for AI services (latency, throughput, cost efficiency).

Identify and mitigate risks related to hallucinations, bias, safety, and edge cases.

Define and track AI quality KPIs (task success rates, precision/recall, latency, etc.).

Participate in design and architecture reviews to ensure systems are testable, observable, and resilient.

Mentor engineers and contribute to raising the bar on AI quality engineering practices.
