You will guide decisions across model quality, reliability, latency, and cost, connecting technical investments to measurable customer value. What you’ll do Lead and grow the team. Hire, coach, and develop ML engineers and scientists. Build a culture of ownership, thoughtful experimentation, inclusion, and technical excellence, while developing the team’s next generation of leaders. Set the ML strategy and roadmap.

Set standards for experimentation, validation, release readiness, and production monitoring. Use execution traces and customer feedback to diagnose failures and drive improvements. Optimize performance and economics. Evaluate models and agent architectures against quality, latency, and cost. Make pragmatic decisions about model selection, routing, fallbacks, and inference efficiency. Build trustworthy agent behavior. Partner with Security and Privacy teams on permission-aware actions, prompt injection defenses, data handling, and appropriate escalation or human approval. Partner across the platform. Adopt and help shape shared capabilities for simulation, observability, experimentation, and durable execution. Work with adjacent teams to integrate Custom Agents into broader service workflows. Deliver measurable customer impact. Connect ML improvements to successful automation, reduced handling time, customer adoption, and trust. Communicate progress, tradeoffs, and risks clearly to stakeholders. What you bring A demonstrated track record of leading ML or AI teams and delivering production systems with measurable customer impact.
