Principal Software Engineer - Azure Managed Lustre Filesystem

The Azure Managed Lustre Filesystem (AMLFS) team leads development, deployment, and monitoring of the most popular High-Performance Computing (HPC) parallel filesystem in the world: Lustre. This is a Principal Software Engineer position for the Filesystem subteam of AMLFS whose mission includes but is not limited to: cluster architecture and design of Lustre in the Azure ecosystem, development of novel Hierarchical Storage Management (HSM) technology between Lustre and other Azure storage platforms, performance analysis and optimization of AMLFS, and customer support for the most challenging parallel filesystem bugs or performance anomalies that arise within our product.

As a Principal Software Engineer in the AMLFS Filesystem team you will lead design and development of key features for releases of our product aligned with the mission statement for the subteam above, primarily working within the Lustre filesystem itself, Lustre userspace libraries, and a host of first and third party software that surround and support the filesystem especially as it relates to HSM. You will also perform kernel and userspace debugging for problems arising in the above either internally or from customer escalations, and drive these problems to root cause and solution in concert with other engineers. You will also engage with the open-source Lustre community members to raise problems, file bugs, perform reviews, and upstream changes our team makes to Lustre itself. This opportunity will allow you to further develop expertise in HPC filesystem design, implementation, and debugging, work with a wide audience to help decide direction and prioritization of key product features, and hone leadership qualities as you work with other engineers to implement such features. The AMLFS team works in and is located in Pittsburgh, Pennsylvania, however we remain open to highly aligned and experienced candidates working fully remotely.
