The Windows Ecosystem and Commercial Engagement team (WECE) sits at the center of how Microsoft brings the full power of Windows to life across a global ecosystem of partners, customers, and engineering teams. Our mission is to transform strategic priorities into real-world innovation—connecting technology, insight, and collaboration so Windows continues to deliver outstanding experiences on every device. Within WECE, Hardware Engineering Enablement (HEE) accelerates the integration of modern hardware capabilities into Windows PCs and provides the tools, guidance, and engineering partnership that elevate device quality, performance, efficiency, and user delight across the ecosystem.

We are looking for a self-motivated, innovative, and accountable Software Engineer II to help evolve the next generation of performance assessments within WAT. In this role, you will collaborate across Microsoft to enable fast, smooth, and delightful PC experiences, while applying advances in AI and data to make the toolkit smarter, more reliable, and more impactful for the entire Windows 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. The Windows Assessment Toolkit (WAT), part of the Windows Assessment and Deployment Kit (ADK), is the trusted measurement platform that OEMs, ODMs, silicon partners, and IHVs rely on to evaluate device performance and bring high-quality Windows PCs to market. Our team owns the performance assessments and trace-backed diagnostics that turn Microsoft’s measurement approach into a credible, scalable ecosystem practice.

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.

• Design, develop, and maintain performance assessment solutions that evaluate responsiveness and user experience across Windows devices.
• Build diagnostic and analysis capabilities that transform complex runtime data into actionable engineering insights.
• Investigate performance regressions and identify bottlenecks across operating systems, storage, memory, application, and platform components.
• Develop scalable tooling, trace-processing systems, and automation frameworks that accelerate root-cause analysis and issue resolution.
• Define and maintain performance metrics, measurement methodologies, and reporting standards used across validation environments.
• Collaborate with engineering teams to drive performance improvements and validate optimization efforts.
• Contribute to technical design discussions, architecture reviews, and engineering execellence practices.
• Support a culture of technical excellence through documentation, code reviews, mentoring, and knowledge sharing.
