Microsoft Azure is developing one of the fastest networks in the public cloud. We are looking for individuals with a interest in kernel technologies, software development, and network systems who enjoy taking ideas from concept to production. The Azure Host Software-Defined Accelerated Networking (SDAN) team builds the host platform that enables Software-Defined Networking (SDN) controllers to perform packet manipulation and virtualization at high speeds. This includes developing platform drivers and managing the underlying hardware to support network acceleration as speeds scale from 40 gigabits per second to 400 gigabits per second and beyond.

As a Principal Software Engineer on the Azure Host Networking team, you will deliver software-defined networking capabilities using technologies such as Single Root Input/Output Virtualization (SRIOV), Data Plane Development Kit (DPDK), Linux network acceleration, Remote Direct Memory Access (RDMA), and containers. You will work with state-of-the-art hardware acceleration to build reliable, high-performance, cloud-scale SDN solutions that support diverse scenarios across industries including finance and artificial intelligence. Collaboration with other Microsoft teams, hardware partners, and Linux distribution communities will be essential.

This role offers opportunities for technical leadership and innovation in a fast-paced environment. You will contribute to the evolution of cloud networking and help shape the future of infrastructure at scale.

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.
