Job Description

Cornelis Networks delivers the world’s highest performance scale-out networking solutions for AI and HPC datacenters. Our differentiated architecture seamlessly integrates hardware, software and system level technologies to maximize the efficiency of GPU, CPU and accelerator-based compute clusters at any scale. Our solutions drive breakthroughs in AI & HPC workloads, empowering our customers to push the boundaries of innovation. Backed by top-tier venture capital and strategic investors, we are committed to innovation, performance and scalability - solving the world’s most demanding computational challenges with our next-generation networking solutions.


We are a fast-growing, forward-thinking team of architects, engineers, and business professionals with a proven track record of building successful products and companies. As a global organization, our team spans multiple U.S. states and six countries, and we continue to expand with exceptional talent in onsite, hybrid, and fully remote roles.


We are seeking an Embedded Firmware Engineer with experience writing optimized C code, preferably for fabrics or networks. Ideal candidates will have written C/C++ code with a focus on high performance, optimal efficiency, and low memory footprint. Candidates should have experience writing and debugging C code for embedded processors. The successful candidate who demonstrates strong team-building, collaboration, and leadership skills will have opportunities for growth into a leadership position.


Key Responsibilities

  • Develop optimized C code for embedded processors
  • Collaborate with architects and hardware engineers when designing software architecture
  • Develop and implement standard processes for unit testing; collaborate on CI implementations
  • Review design documents and pull requests from other team members
  • Create and maintain design documents in collaboration with the engineering team
  • Review and provide detailed feedback on firmware and software architecture specifications and design documentation
  • Work with the Software Engineering Manager to identify tasks and build schedules


Minimum Qualifications

  • Early career to 5 years of experience (we level based on capability)
  • Bachelor’s degree in Computer Science or a related discipline, or equivalent training and experience
  • Proficiency in C or C++ (able to read/write bitfields, manage buffers safely, and reason about endianness)
  • Familiarity with development tools and toolchains, including GCC and/or Clang, Make, CMake, Git, and bug tracking software (e.g., Jira, GitHub)
  • Familiarity with debugging tools used in embedded environments (e.g., logic analyzers, JTAG debuggers, and innovative logging methods for analysis and debugging)
  • Comfort working in Linux user space and with basic system tools; familiarity with sockets or message-based I/O
  • Understanding of binary protocols, including framing, headers, IDs, checksums/CRC, and simple state machines
  • Exposure to at least one low-speed or board-level interface (I²C/SMBus, SPI, UART) through coursework, labs, or projects
  • Ability to read technical standards/specifications and translate them into working code and tests
  • Growth mindset: eager to learn PLDM and MCTP deeply and deliver production-quality code


Preferred Qualifications

  • Familiarity with DMTF standards such as MCTP (DSP0236/37/38/39) or PLDM (DSP0240/41/45/48; 0267/0257). Prior production experience is not required—interest and aptitude are sufficient.
  • Experience with Python for test harnesses, Wireshark dissectors, logic analyzer traces, or OpenBMC tooling (libmctp, libpldm, pldmtool)
  • Basic understanding of embedded development (RTOS) or Linux kernel subsystems is a plus
  • Experience with:
  • ARM or other RISC processors in an embedded environment
  • RISC-V processors
  • PCIe/VDM
