Software Engineering IC4

Overview

As a Senior Software Engineer on Project Strong ARMed, you will be part of a strategic initiative to accelerate Microsoft’s transition to ARM64 architecture across the E+D (Experiences & Devices) division. This role is central to enabling the adoption of Microsoft’s first-party silicon, Cobalt 100, by leveraging AI agents and automation to port existing x64 workloads to ARM-compatible.

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.

Responsibilities

• Build and deploy AI-powered software engineering agents that automatically port codebases from x64 to AnyCPU and Windows to Linux.
• Develop the engineering systems and software ecosystem that will enable hardware-agnostic workloads across all our E+D services.
• Drive adoption of Cobalt 100 and Cobalt 200 processors that deliver 150% and 65% performance-per-TCO advantages respectively over traditional Intel/AMD offerings.
• Shape the future architecture that will power Microsoft 365 and Copilot for the next decade.
• Collaborate with engineering and research teams to design and implement scalable systems that automate the migration of large-scale software from x64 to ARM64 using generative AI and program analysis.
• Evaluate service dependencies and ARM64 compatibility and contribute to the development of AI agents (e.g. Chronicle, Bandish) that generate pull requests for code base porting.
• Support emulation-based deployment and native ARM64 porting of services running on Windows VMSS, EAP, Service Fabric and COSMIC Linux.
• Act as a DRI for ARM64 migration efforts, ensuring system reliability and performance during transition phases.
