Senior Software Engineer - Microservices & Windows Imaging

Overview Windows is one of the largest codebases in the world, running on more than a billion devices. Windows + Devices powers experiences for users worldwide, building the platforms and products that create meaningful experiences across Microsoft and leading the Windows and Surface products through deep partnership across the company and with OEM partners. The Windows Engineering System is the backbone that lets Windows engineers design, code, build, validate, and ship at massive scale, securely and with high quality. As part of the Windows Build Team, the Media Creation Service operates an Azure-enabled, microservices-based platform which orchestrates more than 300k discrete compute jobs every day. Our services operate with near 100% uptime to enable and empower Windows developers to deliver industry leading experiences as well as enabling business-critical and time-sensitive workflows related to testing, flighting, shipping, and servicing Windows. Successful solutions in this domain require solid systems thinking to navigate a complex engineering ecosystem, support legacy products and workflows, and evolve the platform to enable cutting-edge Windows experiences. We are looking for a Senior Software Engineer who combines deep technical judgment with practical execution to lead significant improvements to our tools, processes, and microservices. You will strengthen reliability, quality, efficiency, security, and developer productivity while modernizing the platform without disrupting critical workflows. You will join a collaborative team that values engineering fundamentals, curiosity, inclusive design, modernization, and learning from production. We explore AI-assisted engineering tools and advanced models to improve how we investigate, build, review, and operate software, pairing experimentation with rigorous validation, responsible use, and sound engineering judgment. Team members support one another through design and code reviews, mentoring, incident response, and shared ownership of outcomes. 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.

Set technical direction for improvements to platform reliability, performance, security, maintainability, and developer experience. Partner with product teams and Engineering Systems organizations to integrate new workflows while protecting compatibility, scale, and operational continuity. Establish measurable success criteria, telemetry, and operational signals that make regressions and customer impact visible. Develop and improve AI-assisted engineering workflows for investigation, implementation, review, and operational response while maintaining solid validation and engineering judgment. Diagnose complex failures across source, build orchestration, toolchains, infrastructure, dependencies, and artifact production, driving root-cause fixes rather than recurring mitigations. Advance secure software-supply-chain practices, including dependency governance, provenance, artifact integrity, and compliance automation. Mentor engineers through design reviews, code reviews, debugging, and project leadership, raising the technical capability of the broader team. Lead incident response for high-impact build failures and convert operational learning into systemic reliability improvements. Participate in an on-call rotation and respond to incidents that affect service availability or critical business workflows.
