Job Description

Responsibilities

• Define the long-term architectural direction for Windows Search, including indexing pipelines, retrieval systems, ranking, and semantic enrichment.
• Lead complex, cross-team technical efforts spanning OS components, cloud-assisted pipelines, and on-device AI systems.
• Serve as the architectural authority for Search-related design reviews, tradeoff discussions, and platform decisions.
• Drive architectural clarity across boundaries: Search Platform, Indexer, AI models, telemetry, reliability, and user-facing surfaces.
• Ensure Search systems meet high reliability, performance, and quality bars, informed by telemetry, RQV signals, and customer impact.
• Anticipate future needs for agentic and AI-driven Search, identifying capability gaps and guiding multi-year investments.
• Partner with Product Managers to translate customer scenarios into durable technical primitives and measurable quality signals.
• Mentor senior engineers and architects, raising the bar on design rigor, system thinking, and operational excellence.
• Influence engineering standards, design patterns, and best practices across Search and adjacent platform teams.

Qualifications

Required/Minimum Qualifications:

• Bachelor's Degree in Computer Science or related technical field AND 6+ years technical engineering experience with coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, or Python.
  • OR equivalent experience.
• Extensive experience defining and evolving end-to-end Search architectures, including ranking, retrieval, graph-based systems, and platform/substrate layers, with a proven track record of setting architectural direction, guiding multiple teams, and shaping long-term platform strategy across organizational boundaries, with solid hands-on knowledge of ranking, retrieval, graph-based systems, and substrate/platform layers that power large-scale discovery and reasoning experiences.
• Deep expertise in indexing, retrieval, ranking, and query processing in production environments.
• Solid systems programming background with languages such as C, C++, or C#.
• Proven ability to define and communicate architectural strategies that guide multi-year engineering investment.
• Demonstrated cross-org leadership, with the ability to influence without authority and align diverse stakeholders.
• Solid problem decomposition skills and comfort operating in ambiguous technical spaces.
• Advanced understanding of AI-assisted Search concepts, including semantic retrieval, embeddings, evaluation, and responsible AI use.
• Exceptional communication and technical storytelling skills.

Other Requirements: Ability to meet Microsoft, customer and/or government security screening requirements are required for this role. These requirements include but are not limited to the following specialized security screenings:

• Microsoft Cloud Background Check: This position will be required to pass the Microsoft Cloud background check upon hire/transfer and every two years thereafter.

Preferred Qualifications:

• 10+ years of experience shipping commercial software or platform technologies at scale.
• Prior experience owning or architecting end-to-end Search platforms (system, web, enterprise, or OS-level).
• Experience with semantic search, vector search, knowledge graphs, or content understanding systems.
• Familiarity with Windows platform internals, diagnostics, and performance tooling.
• Experience designing Search systems that power agentic workflows or AI-driven user experiences.
• Solid track record of improving architectural health, reliability, and operational maturity of complex systems.
• Demonstrated success influencing product and technical direction across multiple organizations.

Why This Role Matters

Search is foundational to how users and agents understand and interact with Windows. As a Search Architect, your work will directly shape discoverability, trust, and productivity across the OS—and enable the next generation of AI-native Windows experiences.
