About The Position

We are seeking a highly experienced engineer to define and drive the architecture strategy for compliant computation and storage across the Search platform. This leader will shape the long-term technical vision for how Bing processes, stores, governs, and protects data while enabling innovation, AI-powered experiences, and global scale. The role sits at the intersection of large-scale distributed systems, data governance, privacy, security, and regulatory compliance. The successful candidate will partner across Search, AI, Cloud Infrastructure, Security, Privacy, and Legal organizations to build architectures that ensure compliance requirements are embedded into the platform by design rather than treated as downstream controls. As a senior technical leader, you will drive strategic platform investments to power high-scale search traffic and growth, establish architectural standards for compliant data handling, and drive adoption of next-generation storage and computation frameworks that balance performance, cost, resilience, and regulatory obligations. 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. Starting January 26, 2026, Microsoft AI (MAI) employees who live within a 50- mile commute of a designated Microsoft office in the U.S. or 25-mile commute of a non-U.S., country-specific location are expected to work from the office at least four days per week. This expectation is subject to local law and may vary by jurisdiction.
