Partner teams across Agent 365, Dataverse, Dynamics 365 come to us when they need storage that scales, costs what it should, and stands up to enterprise compliance review. The services you build are the substrate for mission-critical business applications used by some of the largest companies in the world, and the same platform now carries a fast-growing set of agentic AI workloads.Microsoft’s mission is to empower every person and every organization on the planet to achieve more. As employees we come together with a growth mindset, innovate to empower others, and collaborate to realize our shared goals. Each day we build on our values of respect, integrity, and accountability to create a culture of inclusion where everyone can thrive at work and beyond.ResponsibilitiesDesign, build and operate storage services and resource-provider APIs on ADLS and Cosmos DB that meet scale, latency and cost targets for agent workloads. Own a service end to end — architecture, code, deployment, on-call, live-site health and the postmortems that follow. Work directly with partner engineering teams to onboard new scenarios onto the platform, and define where the platform ends and the partner begins. Drive cost and performance engineering — storage tiering, capacity planning and the telemetry needed to reason about both. Use AI tooling and agentic development loops in your own work, and bring the patterns that work back to the team and to our partners.
