We are looking for a Senior Software Engineer to join the Experimentation and Configuration Service (ECS) team and help lead the next generation of Microsoft’s safe, scalable, and resilient configuration platform.
As a Senior Software Engineer in ECS, you will often serve as the technical lead for a feature crew or major platform area. You will own complex technical problems end-to-end, define architecture and execution strategy, mentor engineers, influence partner teams, and drive outcomes that improve ECS reliability, customer experience, and engineering velocity.
This role requires strong technical judgment, strategic thinking, and the ability to create clarity in ambiguous problem spaces. You will be expected to go beyond implementation and shape how the team designs, validates, operates, and evolves ECS platform capabilities.
About the ECS Team
The ECS team is responsible for Microsoft’s Experimentation and Configuration platform, enabling safe rollout, continuous configuration delivery, feature experimentation, policy-driven governance, telemetry, and resilient configuration consumption across Microsoft 365 and broader Microsoft workloads.
ECS operates at the intersection of distributed systems, live-site reliability, security, compliance, and AI-native engineering. The team is transforming ECS into an agentic-native Continuous Configuration system by integrating AI coding agents, operational agents, MCP interfaces, automated validation, intelligent troubleshooting, and self-healing workflows into the platform and engineering process.
Why Join Us
This role gives you the opportunity to lead meaningful platform work at Microsoft scale. As a Senior Software Engineer in ECS, you will shape critical configuration infrastructure, improve how Microsoft services safely roll out change, and help define the team’s agentic-native engineering model. You will work on high-impact problems where strong technical leadership, customer empathy, and operational excellence directly translate into safer and faster service delivery across Microsoft.
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.
This position will be open for a minimum of 5 days, with applications accepted on an ongoing basis until the position is filled.
