Principal Software Engineering Manager

Cloud operations are entering a new era. The next generation of infrastructure will not be managed one workflow at a time, but through autonomous systems that can reason, plan, act, and learn across Microsoft’s largest Kubernetes fleets. COSMIC is building that future, and this role will lead the team creating the agentic infrastructure that makes it real.

The COSMIC team, part of the M365 Substrate Core organization, has a bold mission to standardize how we deliver services and build a modern Kubernetes-based compute fabric with turn-key geo-presence, security, high availability, fault isolation, and automated cloud build out. COSMIC is a strategic investment to modernize our compute platform and improve the agility, security, compliance, reliability, and cost efficiency of services across Microsoft.

As cloud fleets continue to grow in size and complexity, operating them increasingly requires more than traditional automation. We believe the future lies in intelligent systems that help engineers move from managing infrastructure directly to defining goals, policies, and operational intent, while the platform handles routine decision-making and execution safely at scale.

We are seeking a Principal Software Engineering Manager to lead a team building autonomous operational capabilities for COSMIC.

This team is responsible for the agentic infrastructure, intelligent operational systems, and learning capabilities that help engineers manage cloud services at fleet scale. Its mission is to make the safe path the fast path for operating modern cloud services by combining scalable agent systems, operational intelligence, and continuous learning.

In this role, you will lead a team responsible for building the platform foundations that enable fleets of AI agents to reason about, coordinate, and execute operational workflows safely and efficiently. Working closely with product managers, architects, and engineering teams across COSMIC, you will help define how cloud infrastructure evolves from traditional automation toward autonomous operations.

You will build systems that help engineers manage deployment, capacity, resiliency, recovery, and optimization across Microsoft's largest Kubernetes fleets. You will also drive the evaluation, feedback, and learning mechanisms that enable these systems to continuously improve over time while maintaining high bars for safety, reliability, and trust.

Ultimately, this role is accountable for delivering the foundational capabilities that make autonomous operations practical and valuable for services running on COSMIC, helping engineering teams move faster, operate more safely, and focus on delivering customer value rather than infrastructure complexity.
