Overview
Foundations Performance Engineering builds and operates the performance, reliability, and efficiency capabilities that help Agent 365 and the underlying Power Platform, Dynamics 365, and Dataverse infrastructure run predictably at global scale. Our work spans workload management, resource governance, admission control, load balancing, capacity planning, performance diagnostics, cloud efficiency and cost attribution, and live-site engineering. We turn deep telemetry into durable platform capabilities so product teams can grow without trading off customer experience, reliability, or cost.
We are looking for a Principal Software Engineer to set technical direction for the next generation of workload-management and cloud-efficiency systems. This is a hands-on engineering role with organization-wide scope. You will define architecture, write and review production code, guide critical cross-team investments, and lead complex work from ambiguous problem through measured production outcome. Success means lower latency and failure rates, higher infrastructure utilization, faster diagnosis and recovery, and reusable engineering systems that improve every service built on the platform.
Who Thrives in This Role
You are a systems thinker who stays close to the code and the production behavior. You can move from a profile or packet trace to an architectural decision, from a noisy live-site signal to a reproducible diagnosis, and from a promising algorithm to a safely measured rollout. You challenge assumptions with data, explain trade-offs clearly, and prefer durable platform improvements over one-off fixes.
You also move toward the hardest cross-team problems. You are comfortable creating clarity where ownership is distributed, priorities compete, and the right answer requires both deep technical judgment and sustained influence. At this level, you multiply the effectiveness of other engineers while remaining accountable for concrete shipped outcomes.
Why This Role Matters
Performance engineering is where customer experience, reliability, and cloud economics meet. The systems you shape will determine how efficiently critical business platforms use capacity, how gracefully they behave under stress, and how quickly engineering teams can understand and correct problems. The impact compounds across services, regions, and customers.
