THE ROLE

Staff Engineer for a group of engineers with responsibility for Linux and VMWare initiator stack behavior as well as Fibre Channel and NIC drivers on Pure storage array.

WHAT YOU'LL DO

The Kernel and Driver development team is responsible for several areas

• Dealing with middle ware C++ modules
• Maintain Linux kernels for internal testing
• Documenting supported configurations for customers
• Responsibility for evaluating Linux initiator behavior and optimizing for Pure Storage Flasharray. This includes correctness as well as optimizing for performances. Will contribute bug fixes and enhancements to Linux upstream. Analyze and debug difficult Linux bugs to optimize Flasharray attachment.
• Responsible for maintaining Purity’s Fibre Channel SCSI (FCP) target driver. Maintenance includes driver updates for enhancements, bugs fixes and new hardware.
• Resolve difficult Fibre Channel bugs found internally or externally and enhance the resilience of Pure’s FC stack. This includes projects around multipathing and link health.
• Responsible for maintaining NIC drivers on Pure’s storage systems.
• Working for a team that deals primarily in various storage area network protocols such as Fiber Channel and Ethernet.
• On the initiator side, the team will be responsible for Linux initiator behavior attached to Flasharray. Focus is on NVME (ROCE, FC, TCP/IP) but also includes FC-SCSI (FCP) and iSCSI interfaces. This includes software development/fixes for Linux initiator stack, debugging initiator problems, and creating compatibility documents for Purity. For VMWare, focus is on debugging issues with VMWare as an initiator, and creating compatibility documentation.
• For FibreChannel and NIC Drivers, focus is responsibility for FC-SCSI driver stack for storage side and responsibility for NIC drivers on networking side. This includes responsibility for related code, utilities, enhancements supporting RAS, as well as debugging failures found internally and in the field.

WHAT YOU BRING

Must Have:

• Strong experience writing device drivers and/or kernel development for Linux/Unix. Prefer experience in storage and/or networking drivers
• Minimum 8 years of development experience, but expect that typically candidates would have 10+ years experience.
• Experience with software development using C and C++, along with Python
• Experience writing Linux storage device drivers, (including some sets of Fibre Channel, NVME, ROCE, block and multipath modules).
• Experience with performance analysis/optimization for storage systems or protocols
• Demonstrated experience debugging difficult protocol/kernel/system issues
• Experience designing and implementing significant components in storage protocol stacks and storage systems.
• Strong understanding of PCIe Gen4/Gen5 architecture, HBA behavior, DMA, and storage transport bottlenecks.
• Experience leading other engineers technically. Should be able to mentor more junior engineers and lead other engineers in an overall project. Should demonstrate on time delivery with high quality.

Good to Have:

• Experience developing test automation
• Experience with storage protocols: either SCSI (FC-SCSI or iSCSI/FCP) and/or NVME Fabrics (NVME/ROCE, NVME/TCP or NVME/FC) will be an advantage.
• VMWare experience, with understanding of their initiator stack will be an advantage
• Experience upstreaming Linux code is preferred
• Experience with network protocols, including TCP/IP.
