Do you want to work on a team building planet-scale cloud infrastructure? The advanced architectures systems team is looking for truly exceptional engineers to be part of building next generation of datacenter and enable cloud-based AI workloads. Our work encompasses hardware, compilers, distributed systems, networking, and data-center technologies.

This is your chance to impact the future of computing by contributing to the tools and technologies underpinning Azure's accelerated computing platform. Our team's innovative solutions are used to build and optimize the hardware accelerators that power some of Microsoft’s most important and strategic projects in the cloud.

Our software team works at the hardware/software interaction boundary and co-designs those interfaces and network protocols with partner hardware teams. The software team is creating the software abstractions, libraries, and tools that developers, compiler teams, and frameworks will use to program accelerators, connect them to compute workload and build high-bandwidth, low-latency interconnect between accelerators. If you are excited about working on new and exotic hardware, embedded systems, compiler or operating system internals then this is a great team to join.

We are looking for a collaborative software engineer to work directly with our product group and partner teams. You will be developing software that runs on or managers specialized accelerators and providing technical guidance to peer engineers on the team. You will also work closely with other networking teams (Azure Networking and Core OS), and the hardware and other software teams building the accelerator. Key components for success in this role will be the ability to learn and adopt relevant new technologies, tools, methods and processes from Microsoft, industry, and the research community, while developing the team’s ability to consume these technologies.

As part of the Cloud Accelerated Systems and Technologies team, you would join a cross-discipline team of highly capable and motivated people in the Azure Hardware Systems Group. You will be expected to collaborate across multiple workstreams and roles like architects, program management leads and engineering leads across the Azure Hardware Systems Group. Excellent communication and presentation skills are important to be able to work with these partners and our customers.
