The role emphasizes credibility, writing and teaching to scale agentic features, with a focus on reliability, observability and cost control across 50+

Qualifications

• 5+ years in software engineering with cross-team influence at Staff/Principal level or equivalent.
• Strong fundamentals: coding, API design, concurrency, data modelling, testing, CI/CD.
• Agentic systems in practice: orchestration, tool calling, multi-step planning, memory and state.

• Write production-grade code across production services, experimentation harnesses, and internal tooling to make agentic capabilities easy to adopt.
• Make AI systems measurable and trustworthy: datasets, evals, CI regression suites, guardrails, telemetry on latency, quality, token spend and failure modes.
• Set security standards: collaborate on system design, internal protocols and API standards, and contribute to Engineering Committee.
• Lead through reviews, technical discussions, design docs and workshops; mentor and foster engineering excellence.
