PCIe Software Engineer
Operating right where hardware meets software, the Platform team builds the foundation for our networking ASICs and supporting infrastructure. PCIe software engineers write the code that manages high speed communication between hardware components in our switches. We work with hardware, diagnostics, and software engineers to maximize bandwidth and improve reliability on the PCIe links.
As part of this team, you'll work on projects like:
- Bringing up PCIe links on new hardware designs
- Tuning PCIe parameters on root ports, bridges, and end points
- Modifying the Linux PCI drivers and virtual memory allocation
- Using AER and DPC to improve error visibility and resiliency
- Developing userspace software that mediates between networking ASICs, FPGAs, and PCIe bridges
- Measuring hardware read and write performance
