The posting

Overview

Microsoft is a company where passionate innovators come to collaborate, envision what can be and take their careers to levels they cannot achieve anywhere else. This is a world of more possibilities, more innovation, and more openness in a cloud-enabled world. The Business & Industry Copilots group is a rapidly growing organization that is responsible for the Microsoft Dynamics 365 suite of products, Power Apps, Power Automate, Dataverse, AI Builder, Microsoft Industry Solution and more. Microsoft is considered one of the leaders in Software as a Service in the world of business applications and this organization is at the heart of how business applications are designed and delivered.

We are looking for a Principal Software Engineer to join our team!

The Agent 365 Foundation team owns the compute platform that Dynamics 365, Power Platform, and Copilot agent workloads run on, specializing in container orchestration and the isolation layers that keep tenant workloads secure. As a Principal Software Engineer, you will set the technical direction for that platform, own its hardest architectural decisions, and lead multi-team efforts that span compute, networking, identity, and capacity. You will be part of a team of engineers who thrive on solving complex problems at scale while doing it with impeccable quality.

This is infrastructure engineering with a direct line to the product. The services you lead are the substrate for mission-critical business applications used by some of the largest companies in the world, and the same platform now carries a fast-growing set of agentic AI workloads. Your design choices show up directly in reliability, deployment velocity, and infrastructure cost across the organization.

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

  • Sets technical direction and owns the architecture for the platform services and APIs that provision, scale, and secure containerized compute across Azure Container Instances, Service Fabric, and Azure Kubernetes Service.
  • Drives multi-team, multi-quarter platform investments from ambiguous problem statements through design, staged rollout, and live-site operation, and holds the resulting systems to Microsoft's reliability, security, and compliance bar.
  • Leads the networking, identity, and isolation strategy of the platform — virtual network integration, subnet delegation, managed identity, and container isolation — and drives secure design principles, least-access practices, and formal validation of security invariants across the team, including the safe execution of untrusted and AI-generated code.
  • Leads efforts on using debugging tools, tests, logs, telemetry, and other methods, and proactively leads verification of assumptions while developing code before issues occur in production. Leverages minimal telemetry data, triangulates issues, and resolves them with minimal iterations.
  • Leads incident retrospectives to identify root causes of problems, the implementation of repair actions, and the identification of mechanisms to prevent incident recurrence, and takes a leading role in the on-call rotation for the services the team owns.
  • Drives capacity planning and infrastructure cost efficiency using telemetry and usage data, and partners with Azure compute, networking, and identity teams to align platform roadmaps with where the agentic workloads are heading.
  • Mentors engineers, raises design and code quality through reviews, and grows the technical depth of the wider organization by sharing established methods and best practices.
  • Embody our culture and values.

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
