Senior Software Engineer (Azure HPC/AI)

Job description

Do you want to help power the world’s most demanding Artificial Intelligence (AI) and High Performance Computing (HPC) workloads on Azure?

The Azure HPC/AI Software team is expanding our engineering presence in Dublin to accelerate innovation in Azure HPC/AI Images and Microsoft HPC Pack — powering some of the world’s most demanding HPC and AI workloads — from large-scale physics simulations, climate modeling, and computational chemistry to AI model training and inferencing on thousands of Graphics Processing Units (GPUs).

Azure HPC/AI Images are pre-configured, performance-optimized Operating System (OS) images that integrate the latest HPC and AI software stacks — including Message Passing Interface (MPI) libraries, GPU drivers, communication runtimes, container runtimes, and high-speed networking drivers — enabling customers to run cutting-edge HPC/AI workloads on Azure with minimal setup time and maximum performance.

Microsoft HPC Pack provides enterprise-class cluster management, job scheduling, and monitoring for hybrid and cloud-native HPC environments, enabling customers to orchestrate workloads across on-premises and Azure resources seamlessly.

As a Senior Software Engineer, you will be responsible for building and optimizing Azure HPC/AI Images, integrating the latest MPI libraries (Intel MPI, Open MPI, MVAPICH2), GPU computing frameworks (Compute Unified Device Architecture (CUDA), NVIDIA Collective Communication Library (NCCL), Radeon Open Compute (ROCm), Radeon Collective Communication Library (RCCL)), high-speed networking (NVLink, InfiniBand, Remote Direct Memory Access (RDMA), Libfabric, Unified Communication X (UCX)), and parallel file systems (Azure Managed Lustre) to deliver maximum performance and reliability.

In addition, you will architect and evolve a state-of-the-art test infrastructure that ensures Azure HPC/AI Images consistently deliver peak performance and reliability across various host-level and containerized benchmarks.

You will work hands-on with cutting-edge hardware and collaborate closely with industry-leading partners to integrate and optimize these technologies for Azure customers.

In addition, you will enhance the support of Microsoft HPC Pack for its job scheduling and cluster management capabilities serving global enterprise customers.

Through your work, you will directly contribute to the global-scale Azure HPC/AI infrastructure that powers scientific breakthroughs, drives AI innovation, and supports mission-critical workloads across industries.

As a senior member of our team, you will participate in the hiring, training, mentoring, and development of junior staff and lead virtual teams of engineers to solve complex problems.

You will work closely with team leaders and other senior developers across the organization in our mission to deliver the best experience to our customers.

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.
