Responsibilities
- Design, build, and ship agent efficiency systems, per-task cost and quality telemetry, smart model routing, durable and deferred execution, and continuous optimization, into the Agent Development Kit and Vertex AI serving stack.
- Measure where cost and latency go, and turn that data into targeted engineering work.
- Shape the team's efficiency roadmap, and help set technical direction for how enterprise agents run in production.
- Benchmark efficiency techniques on both open source benchmarks and real first-party and enterprise agent workloads to prove cost and latency wins hold up without regressing accuracy.
- Partner with the team's evaluation engineers, model-serving teams, and product teams to close optimization loops on measured behaviour and land changes across Agent Platform.
