We’re looking for a Principal Software Engineer (Frontend/Full Stack) to help shape the future of shopping in Copilot. This role is for an engineering leader who can set technical direction, drive end-to-end execution across client experiences, services/APIs, data contracts, telemetry/experimentation, and operational excellence, and raise the bar on craftsmanship and reliability at scale.

You’ll operate as a multiplier: influencing architecture and quality across multiple workstreams, partnering closely with Product, Design, Data Science, and other engineering teams, and unblocking delivery by diving deep wherever needed,frontend, backend, or data/measurement. You’ll bring strong engineering judgment, a bias for clarity and velocity, and an ability to translate customer problems into durable technical solutions.

Microsoft’s mission is to empower every person and every organisation on the planet to achieve more. As employees we come together with a growth mindset, innovate to empower others, and collaborate to realise 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 expectation is subject to local law and may vary by jurisdiction.

Set technical direction and drive execution for Copilot Shopping experiences end-to-end, with a strong bar for frontend quality (UX polish, accessibility, performance, reliability). Lead architecture across the stack: client (web/mobile), services/APIs, data contracts, telemetry/experimentation, and operational tooling. Partner with Product, Design, and Data Science to define success metrics, instrument telemetry, run experiments, and iterate based on outcomes.

Drive engineering excellence across the team via design reviews, code reviews, testing strategy, CI/CD, and performance/quality standards. Own live-site health: improve observability, monitoring/alerting, incident response, and reduce time-to-diagnosis through systemic fixes. Decompose ambiguous problems, align stakeholders, and deliver durable solutions that improve scalability, maintainability, and developer velocity.

Mentor senior engineers, raise the technical bar, and amplify impact through documentation, best practices, and cross-team collaboration.
