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

Lead global sourcing strategy for stamped, formed, and expanded mesh metal parts. Develop supplier relationships, negotiate contracts and pricing, analyze markets and risks, optimize costs and lead times, and collaborate cross-functionally to qualify suppliers and execute sourcing plans.

Lead design and implementation of a unified HIL/SIL test platform: define requirements, architect system, build device drivers and user interfaces, scale SIL cloud infrastructure, and troubleshoot electrical and software systems across hardware-software integration.

Lead design, prototyping, and integration of mechanical subsystems for iron-air battery packs. Build thermal analytical models, validate first-of-a-kind prototypes, optimize for manufacturability and cost, manage vendor and manufacturing handoff, collaborate with electrical/controls, and mentor junior engineers while championing lab safety.

Design, develop, and own component-to-system-level test strategies for energy storage products. Design electromechanical and high-voltage test systems, troubleshoot test stands, select DAQ and sensors, analyze large test datasets, report findings, and lead continuous improvement and mentorship of junior staff.

Lead and grow a mechanical engineering team designing gas systems for iron-air batteries. Own architecture, design-for-manufacturing, verification and testing, failure root-cause analysis, vendor and manufacturing transitions, hiring, and cross-functional coordination to release high-volume production-ready designs.

Lead design verification and validation testing for AMU PCBA and panel assemblies. Develop DVP&Rs, verify communication protocols (CAN-FD, Ethernet, RS485), validate sensing, actuation, power distribution, and safety/fault management. Automate tests (Pytest), analyze data, report results, and collaborate with hardware/firmware teams to root-cause issues.

Lead a mechanical design team to take structural, enclosure, and sealing systems from concept to high-volume production. Drive FEA and testing, ensure manufacturability (sheet metal, stampings, weldments), establish design best practices, mentor and hire engineers, and work cross-functionally to meet requirements and verification plans.

Lead system- and interface-level verification testing for multi-day battery products. Develop risk-based test strategies, execute and analyze high-fidelity test data (including vibration), drive DFMEA, mentor engineers, influence design for robustness, standardize test tools/workflows, and coordinate multi-site and external lab test execution.

Design and execute test plans to achieve UL1998 certification and harden bootloaders. Review firmware, develop test code and frameworks (C, Python), build hardware test fixtures and instrumented automated test benches, and document traceability between safety requirements and test artifacts for compliance.

Design and prototype mechanical and electro-mechanical module components using 2D/3D CAD. Perform structural analysis, manufacturability and cost-down work, vendor transitions, compliance testing, and support line bring-up to move designs into high-volume production while collaborating with Test, Manufacturing, Supply Chain, and Cell/Enclosure teams.
