SHOULD YOU ACCEPT THIS CHALLENGE...

The Kernel and Driver development team is responsible for several areas

• 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.
• 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 enhancing 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.
• Dealing with middle ware C++ modules

Role Description

• Team lead 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.
