Principal Software Engineer

Microsoft Azure is building the fastest network in public cloud. We are seeking candidates who live and breathe kernels, love to code and to build network systems and services, taking things from idea to production. The Azure Host Networking team is where the rubber meets the road for Software-Defined Networking (SDN) – we create the host platform that allows SDN controllers to perform arbitrary packet manipulations and virtualization, with very high speed on various computer architecture & platform.

We build the Azure Virtual Switch where the action happens in software, and own the underlying hardware platform on the host that enables us to scale SDN as the network moves from 40Gbps to 100Gbps, 200 Gbps and beyond!

The Datapath team created all the host network virtualization capabilities, as well as the high speed Remote Direct Memory Access (RDMA) platform\that scaled Azure Storage. We also build in other larger scale cloud SDN scenarios for performance, security and reliability, many of which are used by large scale workload like online commerce, AI, big data, etc.

As a Principal Software Engineer working in this field, the position will allow you to grow your knowledge about large scale system design\implementation\maintenance, develop deep understanding on cloud engineering and accelerate your career growth in the cloud business.

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.
