Principal Software Engineer

Artificial Intelligence (AI) is transforming the way developers build software. At Microsoft, we’re combining the power of .NET, world-class developer tools, and cutting-edge AI to reimagine the entire development experience — from the first line of code to deployment in the cloud. Our goal is to create smarter, faster, and more intuitive tools that help millions of developers turn ideas into reality.

• Partner with stakeholders to define user scenarios and system requirements for developer tools.
• Lead architecture, design, and technical direction for large-scale developer tooling systems and platforms.
• Write high-quality, extensible, and maintainable code while modeling and mentoring best coding practices across teams.
• Drive optimization, refactoring, reuse, and diagnostics to improve code quality, performance, and ROI.
• Lead design and review of testing strategies, with strong coverage across unit, integration, and system tests.
• Mentor others on design patterns, telemetry integration, and verification strategies.
• Set high standards for code reviews, diagnosability, and maintainability across the org.
