Top Tech Jobs & Startup Jobs in San Francisco Bay Area, CA

Design, develop, and maintain platform firmware, BMC/OpenBMC management stacks, and FPGA/CPLD logic for board bring-up and system management. Own low-level boot sequencing, debug CPU/GPU/PCIe/hardware interactions, implement Redfish/IPMI interfaces, and build fault recovery, secure boot, and autonomous reboot systems for orbital deployments.

Manage high-volume accounts payable including two- and three-way matching, invoice investigation and resolution, vendor master maintenance, payment runs (ACH/wire/check), expense reimbursements, month-end/year-end AP reconciliations, 1099 and tax filings, audit recordkeeping, vendor communication, and process improvement to strengthen internal controls.

Design and implement complex multilayer PCBs for spacecraft avionics, power, RF, and compute systems. Translate schematics into manufacturable layouts, define stackups and routing, perform SI/PI and impedance analysis, ensure thermal and mechanical integration, produce fabrication and assembly documentation, and drive DFM/DFA/DFT and PCB standards while supporting fabrication, testing, and supplier partnerships.

Lead end-to-end development of precision gimbal mechanisms for laser communications payloads, including design, analysis, procurement, integration, and qualification. Define performance requirements, perform mechanism-level analysis, manage suppliers, develop test and qualification plans, and collaborate with optics, controls, and systems teams to deliver flight-qualified hardware.

Design, develop, and validate board-level RF hardware for free-space optical communications up to 50 Gbps. Own RF driver/receiver circuitry, high-speed RF/analog PCB layout, signal integrity analysis, simulation and lab characterization. Collaborate with optics, mechanical, firmware, and systems teams to integrate and flight-qualify RF/optical subsystems and support testing, troubleshooting, and documentation.

Design, develop, integrate, and qualify spacecraft battery systems from concept through flight. Responsibilities include pack/module architecture, BMS development (SOC/SOH, cell balancing, protections), cell chemistry selection, sizing and degradation modeling, thermal and safety strategies, environmental qualification and testing, manufacturing support, and on-orbit performance monitoring and failure investigation.

Design, build, and qualify high-power fiber laser and amplifier systems and fiber-optic subsystems for space applications. Characterize lasers (linewidth, phase noise, RIN), model nonlinear effects, perform fiber splicing and assembly, design coherent receivers, and execute optical test plans and documentation for space qualification.

Lead design of high-voltage, high-power DC/DC conversion and distribution systems for terrestrial and orbital GPU compute. Architect multi-stage power conversion, custom magnetic components, PCB layouts, power integrity and thermal solutions, validate prototypes to production, and mentor the power systems team while coordinating with mechanical, thermal, and systems engineers.

Design, implement, and verify FPGA/RTL for compute payloads: sensor interfaces, deterministic pixel capture, high-throughput DDR/DMA datapaths, and AXI register interfaces to embedded Linux. Drive synthesis, timing closure across Zynq/Versal/Cyclone targets, testbench-based verification and lab bring-up. Support Petalinux, driver integration, platform firmware/BMC bring-up, board integration, anomaly investigation, and CI/regression for FPGA workflows.

Lead and build Cowboy Space's export compliance program (ITAR/EAR/OFAC). Own classification, licensing, TCPs, denied-party screening, audits, training, and partner with engineering, supply chain, and leadership to enable compliant international operations.
