Electrical Engineer, Hardware Systems

About the role Design and bring up the electrical hardware that turns our AI accelerator silicon into working systems — boards, power delivery, and system-level electrical design from schematic through lab bring-up and validation. You'll sit at the seam between silicon/ packaging and the systems our accelerators run in, and own the board-level hardware that makes them work. What you'll do Own schematic design and drive PCB layout for accelerator boards and system hardware — high-speed digital, power delivery, and clocking Design and validate power-delivery networks (PDN) and rails for high-current accelerator silicon; partner with SI/PI and packaging on the board <-> package interface Bring up new boards in the lab — debug, characterize, and validate against spec using scopes, logic/protocol analyzers, and power/thermal instrumentation Drive component selection, DFM/DFT for boards, and work with contract manufacturers and vendors through fab, assembly, and yield Partner across silicon, packaging, SI/PI, thermal, and firmware/bring-up teams to close electrical issues end to end Use and develop AI-assisted tool flows to accelerate design and debug What we're looking for BS/MS in Electrical Engineering plus 5+ years in board/system-level electrical design for complex high-speed digital systems Schematic capture and PCB design (Altium, Cadence Allegro, or equivalent), including high-speed interfaces (DDR/LPDDR, PCIe, SerDes) and power-delivery design Hands-on lab bring-up and debug: oscilloscopes, logic and protocol analyzers, power and thermal characterization Solid grounding in signal integrity, power integrity, and EMC at the board level (Optional) High-current PDN for accelerators/GPUs; server/board design at hyperscale; FPGA-based systems; firmware / low-level bring-up; thermal co-design; ANSYS HFSS/SIwave or equivalent EM tools Compensation Final offers depend on level, location, and skills relevant to the role. Additional compensation: equity grant per company guidelines; medical / dental / vision; 401(k); standard PTO.
