Description
OverviewAre you interested in solving large‑scale search problems and building next‑generation of Query Understanding solutions powered by LLMs and SLMs? If yes, the Bing Orca team is for you!
The Orca team is a research‑driven applied science and engineering group building the next generation of efficient, scalable, and highly capable AI models. Our mission is to push the boundaries of model reasoning, compression, and alignment—making advanced intelligence accessible, reliable, and cost‑effective across Microsoft’s ecosystem.
We’re known for pioneering techniques that help compact models learn rich reasoning abilities from frontier‑scale teachers. But we don’t stop at research: we also own the end‑to‑end infrastructure, tooling, and runtime systems that bring these models to life in production.
Our work spans deep research, large‑scale engineering, and real‑world product impact:
Advanced Model Research
Develop novel distillation and compression methodsExplore chain‑of‑thought, multi‑step reasoning, and structured supervisionBuild evaluation frameworks that measure reasoning, robustness, and safetyProduction‑Grade Infrastructure & Hosting
Own the full model‑serving stack for Orca modelsBuild high‑performance inference pipelines optimized for latency, throughput, and costMaintain high availability, stability, and reliability across global deploymentsDesign scalable systems that support rapid experimentation and safe rollout of new model variantsTraining & Experimentation at Scale
Run large‑scale training jobs and ablation studiesDevelop internal tools that accelerate research velocityCollaborate with platform teams to optimize compute efficiencyReal‑World Impact
Our systems & models serve users in 100+ markets worldwide, handling 100M+ queries and interactions every day.
We are hiring an Applied Scientist II to join our world of search retrieval, ranking, relevance optimization, driving real user impact in production systems at global scale.
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.
