Overview

The Windows Ecosystem and Commercial Engagement (WECE) team is where Microsoft’s Windows vision meets the energy, scale, and innovation of a global ecosystem. We connect partners, customers, and engineering teams to turn strategic priorities into breakthrough experiences that reach people on every Windows device. Within WECE, Hardware Engineering Enablement (HEE) helps bring modern hardware innovation to life on Windows PCs—delivering the tools, guidance, insights, and engineering partnership that elevate device quality, performance, efficiency, and user delight across the ecosystem.

Performance and responsiveness are fundamental to every Windows device—they shape how customers start their day, launch apps, multitask, create, connect, and stay in flow. Our team partners with OEMs, ODMs, silicon providers, and IHVs to boost system performance across Windows hardware and software, using telemetry, automation tools, and system-level analysis to drive measurable improvements.

We are looking for a self-motivated, innovative, and accountable Senior Software Engineer with solid debugging, troubleshooting, and analytical skills. In this role, you will diagnose performance regressions and non-deterministic behavior, translate data into actionable engineering recommendations, and collaborate across Microsoft and the ecosystem to optimize startup, application responsiveness, memory, storage, and I/O performance—helping deliver fast, smooth, and consistently delightful Windows PC experiences.

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.
