  • Bachelor’s Degree in Computer Science or a related technical field and 6+ years of technical engineering experience coding in languages such as C++ or Python.
  • Ability to meet Microsoft, customer and/or government security screening requirements.

Responsibilities

  • Define technical vision, architecture, and multi-release strategy for critical AI framework capabilities.
  • Lead ambiguous, cross-stack investigations spanning models, frameworks, compilers, runtimes, systems, services, and silicon.
  • Establish common measurement, automation, observability, and engineering mechanisms for scalable platform capabilities.
  • Drive measurable improvements in model onboarding velocity, runtime performance, reliability, and Azure capacity efficiency.
  • Influence architecture and priorities across teams and align stakeholders around clear decisions and execution plans.
  • Provide hands-on technical leadership through prototypes, implementation, design and code reviews, and operational readiness.
  • Raise the engineering bar by mentoring junior engineers and advancing standards for quality and collaboration.
