Cornelis Networks is seeking a Senior Embedded Firmware Engineer with experience writing optimized C code, preferably for fabrics or networks. Ideal candidates will have written C/C++ code for high performance, optimal efficiency, and low memory footprint. The candidate will have experience writing and debugging C code in embedded processors. The successful candidate who demonstrates strong team building, collaboration, and leadership skills will have opportunities for growth into a leadership position.

• Develop optimized C code for embedded processors
• Collaborate with architects and hardware engineers when designing the software architecture
• Develop and implement standard processes for unit test, collaborate on CI implementations
• Review other team members’ design documents and pull requests
• Layout and establish design documents with the engineering team
• Review and provide strong feedback on firmware and software architecture specifications and design specifications
• Work with the Software Engineering Manager to identify tasks and build out schedules

• Bachelor’s degree in Computer Science, or related discipline, or the equivalent in training and experience
• Minimum experience:
  
  ~10 years; we level based on capability
• Experience in C or C++
• Familiarity with software development tools and tool chains including gcc and/or clang, make, cmake, git, bug tracking software (e.g. Jira), Git Hub
• Familiarity with debugging tools used in an embedded environment (logic analyzer, JTAG debugger and innovative methods for logging information for analysis and debug purposes)
• Comfort with Linux user space and basic systems tools; familiarity with sockets or message‑based I/O.
• Understanding of how binary protocols work: framing, headers, IDs, checksums/CRC, and state machines.
• Experience with at least one low speed or board level interface (I2C/SMBus, SPI, UART)
• Ability to read a technical standard/spec and translate it into working code and tests.
• Familiarity with PLDM/MCTP DMTF specifications and an eagerness to learn PLDM and MCTP deeply and ship production quality code.

• Master’s in Computer Science or related discipline.
• Familiarity with any DMTF standards: MCTP (DSP
  0236/37/38/39) or PLDM (DSP
  0240/41/45/48; 0267/0257). You do not need prior production experience; interest and aptitude are enough.
• Experience with Python for test harnesses;
  Wireshark dissectors; logic analyzer traces; or OpenBMC tooling (libmctp, libpldm, pldmtool).
• Basics of embedded development (RTOS) or Linux kernel subsystems is a plus.
• Experience with the following:
• ARM or other RISC processors in an embedded environment
• RISC‑V processors familiarity
• PCIe/VDM
