Job Description

Overview

The Microsoft AI Frameworks team develops the software, performance systems, and engineering tools that enable state-of-the-art AI models to run reliably and efficiently at cloud scale. We work across model architectures, frameworks, compilers, runtimes, libraries, observability, benchmarking, and hardware platforms—including NVIDIA and AMD GPUs and Microsoft silicon. Our engineers, partner with model developers, researchers, hardware teams, and production services to accelerate model onboarding, improve performance and reliability, reduce deployment time and hardware footprint, and turn performance insights into durable platform capabilities.

This is a hands-on technical leadership role for an engineer who can establish direction and lead teams through ambiguous, end-to-end systems challenges. Successful candidates combine strong software engineering fundamentals with deep curiosity about AI workloads, use disciplined measurement to guide decisions, and create alignment across organizational boundaries to deliver measurable production impact.

As a Principal Software Engineer - AI Frameworks, you will serve as a technical lead for high-impact initiatives spanning AI frameworks, performance engineering, benchmarking, and tooling. You will establish technical direction, make consequential architectural decisions, and lead engineers across teams through the design and delivery of solutions that improve model velocity, platform efficiency, and production reliability. You will also identify systemic opportunities, align stakeholders around durable architectures and success measures, and remain hands-on in critical areas of implementation.

At Microsoft, our mission to empower every person and every organization on the planet to achieve more guides how we partner with customers to deliver trusted, impactful solutions. With a growth mindset culture, we innovate responsibly and measure success by shared progress people, teams, and customers. Join us to do meaningful work that changes the world and helps shape what’s next for everyone.
