Job Description
Senior Technical Lead

Job Summary

Candidates with more than 8 years’ experience is mandatory. Own the firmware and embedded software that makes high-speed interfaces train, stay up, and present a usable device or root-complex to the rest of the system. The primary interface family is PCI Express. It also covers related stacks such as CXL, USB4 / USB SuperSpeed, Ethernet MAC/PCS software where the work is link bring-up rather than a full networking product, and similar controller-plus-PHY designs.

Key Responsibilities

  • Lead firmware and embedded software for PCIe and similar interfaces from architecture through first successful link-up on silicon or a representative FPGA / emulation platform.
  • Own controller firmware and link bring-up: LTSSM (or equivalent state machine), speed negotiation, equalization, lane configuration, reset and recovery, error logging, and power states that the interface actually implements.
  • Own the embedded software that sits above that firmware: Linux or RTOS driver, endpoint or root-complex HAL, configuration space / BAR bring-up, basic DMA path, and a golden traffic test the lab can run.
  • Work the boundary with hardware and validation: when a link will not train, decide whether the next action is PHY, controller firmware, host software, board, or the other end of the cable.
  • Define registers, firmware interfaces, and logs so validation and SoC firmware can debug without you in every meeting.

Interfaces in scope

  • Core: PCI Express (device, root complex, or switch port software — whichever the program needs).
  • Adjacent, same skill: CXL, USB4 / USB SuperSpeed, SATA / SAS controller software, Ethernet MAC/PCS bring-up, die-to-die controller software where the job is link state and driver enablement.

 

Skill Requirements

  • Experience in firmware and/or embedded software on high-speed interfaces, with PCIe or similar high speed interface.
  • At least one program owned and technically executed end-to-end:  accountable for the interface firmware and software that took a controller from reset to a trained link and a usable software path (enumeration, a BAR or equivalent, and traffic — not only “LTSSM reached L0 in a log”).
  • Working depth in PCIe link bring-up (LTSSM, speeds, equalization concepts, AER / error handling, config space) and in writing the driver or firmware that operates the controller.
  • Able to read a controller programming guide and a PHY datapack and produce working bring-up code, not only a design presentation.
  • Experience with lab tools used on these links (protocol analyzer, BERT where relevant, vendor PHY utilities) enough to partner with validation.

Other Requirements

Must have skills - Firmware and/or platform software

Good to have skills 

  • PCIe Gen5 or Gen6, or CXL 1.1 / 2.0 / 3.x software bring-up on real silicon.
  • Both endpoint and root-complex software experience.
  • Controller firmware running on an embedded core inside the interface block, not only a Linux host driver.
  • SR-IOV, IOMMU / SMMU programming for the interface, or tight coupling with a custom DMA engine.
  • Multi-die or chiplet link software (UCIe or vendor equivalent) as firmware/driver work.
  • Led a distributed team across a customer lab and an offshore design center
