• Own the platform's reliability, security, monitoring, latency, and cost in production
• Evaluate emerging AI models, AI tooling, and agentic systems and integrate solutions that add value
• Develop a secure self-service environment, within clear guardrails, that enables colleagues to create their own AI-powered applications

This is a senior individual contributor role.
