Help shape the future of cloud infrastructure and artificial intelligence platforms at unprecedented scale. Our team is building the foundational platform capabilities that power large-scale distributed systems, accelerated computing environments, and next-generation cloud services. You will work at the intersection of software, infrastructure, networking, and datacenter technologies to enable reliable, secure, and scalable platforms that support a broad range of business-critical workloads. You will collaborate with engineering teams across Microsoft to advance platform capabilities, accelerate innovation, and improve operational excellence across diverse infrastructure environments.

As a Principal Software Engineer, you will lead the design and evolution of cloud-native platforms, distributed systems, and infrastructure services that support service lifecycle management, resource orchestration, observability, reliability, and automation. You will help guide technical strategy across multiple engineering investments, contribute to architecture decisions involving compute, networking, storage, and platform services, and collaborate across organizations to deliver capabilities that improve platform efficiency and developer productivity. This opportunity will allow you to deepen your expertise in distributed systems and cloud infrastructure, expand your influence across engineering organizations, and contribute to innovations in Artificial Intelligence (AI) infrastructure, graphics processing unit (GPU) platforms, high-performance networking, and large-scale datacenter systems.

Microsoft’s mission is to empower every person and every organization on the planet to achieve more. We cultivate a culture grounded in respect, integrity, accountability, inclusion, collaboration, and continuous learning, enabling individuals and teams to grow, contribute, and make meaningful impact.
