  • Drive code re-use across the organization with firmware and embedded software engineers.
  • Identify and meet deadlines with program managers.
  • Develop embedded firmware running on RISC-V-based controllers.
  • Create Python and C SDKs for SerDes bring-up, calibration, tuning, and diagnostics.
  • Develop Python-based lab tools and GUIs for interactive debug, register access, and validation.
  • Build, regress, and maintain CI infrastructure to ensure code quality and full coverage.
  • Serve as technical or project lead for SerDes firmware on major IP programs.
  • Gather requirements, study high-level designs, develop device interface functions, and create higher-level firmware system designs.
  • Architect and implement embedded C/C++ firmware for hardware calibration, training algorithms, DSP adaptations, and link state management.
  • Define detailed bring-up and validation requirements and meet performance goals with multi-functional teams.
  • Communicate requirements and coordinate execution across multiple teams and sites.
  • Translate bring-up and validation requirements into efficient C/C++ firmware code and well-structured software organization.
  • Translate protocol specifications into internal firmware architecture and documentation.
  • Develop test and debug capabilities to guide hardware design decisions for future product iterations.
  • Debug complex lab and field issues in conjunction with hardware, applications, and validation teams.
  • Drive multi-functional teams and partners to address integration and bring-up challenges.
  • Plan and develop test cases that improve reliability and release quality.
  • Work with external vendors and customers to ensure requirements are met and releases are of high quality.
  • Drive and collaborate across functions to define FW milestones, plan sprints, close tickets, and deliver reliable, high-quality features.
