The Principal Software Engineer will provide technical leadership for AI frameworks and frontier-model serving initiatives, making architectural decisions and leading cross-team optimization efforts across GPUs, Microsoft silicon, runtimes, and related systems. The role also involves hands-on implementation, mentoring engineers, and driving measurable improvements in model onboarding, performance, reliability, and Azure capacity efficiency.
Responsibilities
- Own the technical vision, architecture, roadmap, and multi-release execution strategy for critical AI framework, performance, benchmarking, or developer-productivity capabilities
- Lead technical alignment across teams by shaping architecture and priorities, resolving competing requirements, and holding researchers, product groups, infrastructure owners, and hardware partners accountable to clear decisions, execution plans, and measurable outcomes
- Build technical leadership capacity across the organization by mentoring engineers, developing emerging technical leads, establishing high standards for quality and maintainability, and creating an inclusive engineering culture in which teams can execute effectively at scale
- Steer ambiguous, cross-stack investigations and investments spanning models, frameworks, compilers, runtimes, systems, services, and silicon; set technical priorities, resolve trade-offs, and drive teams to decisions
- Provide hands-on technical leadership by setting the engineering approach, delegating and unblocking critical work, and directly contributing through prototypes, critical-path implementation, design and code reviews, complex debugging, and operational readiness
- Spearhead common measurement, automation, observability, and engineering mechanisms that turn one-off analyses into scalable platform capabilities
- Drive measurable improvements in model onboarding velocity, runtime performance, reliability, hardware utilization, and Azure capacity efficiency
- Embody Microsoft’s culture and values
