Description

  • Own compute hardware from architecture through bring-up with no mid-stream handoff to another team.
  • Design compute boards that deliver at least 10 TFLOPS of processing power for onboard AI/ML inference and science data processing.
  • Architect and implement power delivery networks for high-complexity carrier boards, including 500W+ multi-rail designs with tight sequencing.
  • Integrate GPU or CPU compute modules onto custom PCBs with high-speed coherent interconnects.
  • Define thermal interface requirements and hand off thermal and packaging specifications to the mechanical team.
  • Design and validate high-speed memory and interconnect interfaces, including HBM, DDR5, PCIe Gen 4/5, and 10 GbE+ Ethernet.
  • Implement board-level power monitoring, current limiting, and radiation upset recovery circuitry.
  • Lead hardware bring-up and board-level validation.
  • Diagnose and resolve hardware issues hands-on while collaborating closely with software engineers.

Requirements

  • BSEE with 5+ years of experience designing and bringing up high-speed digital compute boards.
  • Direct exposure to GPU, HPC, or modern accelerator platforms is preferred.
  • Proficiency in high-speed digital PCB design principles, including multi-GHz signaling, dense BGA escape routing, and high layer count stackups.
  • Experience with signal integrity analysis through simulation and measurement.
  • Strong command of power integrity and power delivery network design, including multi-rail architectures, PMIC selection, voltage sequencing, and board-level current limiting.
  • Strong working experience with high-speed serial interface design, analysis, and debug, particularly PCIe Gen 4/5 and Ethernet.
  • Experience writing basic firmware for hardware bring-up and validation is preferred.
  • Hands-on embedded systems debug skills are preferred.
  • Experience with COTS hardware for space applications, including radiation awareness, component derating, and upset mitigation techniques is preferred.
  • Hands-on experience with physical PCB layout for complex, high-layer-count boards with dense BGA packages is preferred.

Benefits

  • Competitive salary with a hiring range of $175,000 to $241,000 USD.
  • Equity as part of the total rewards package.
  • Generous PTO and sick leave policy.
  • Parental leave.
  • Annual learning and development stipend.
  • Additional benefits and perks available through the company’s benefits program.
  • Reasonable accommodation support for candidates who need it.
