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

Builds, modifies, assembles, and tests mechanical, electrical, and fluidic prototypes. Responsibilities include designing parts and fixtures in SolidWorks, fabricating components using 3D printing or machining, integrating hardware, troubleshooting failures, conducting bench tests, and documenting designs and results. The role collaborates with engineers and scientists to improve prototypes and accelerate development. Practical hardware experience is required; a formal engineering degree is not.

Provides executive support by managing leadership calendars, travel, meetings, communications, expenses, records, visits, and events. The role prioritizes schedules, prepares agendas and materials, tracks commitments, follows up on action items, handles confidential information, and resolves administrative issues independently with discretion.

Owns sourcing, purchasing, inventory, and logistics from prototype development through production. Builds supplier networks, negotiates pricing and lead times, manages purchase orders, plans materials from bills of materials and schedules, expedites deliveries, resolves supplier and quality issues, mitigates supply risks, and establishes scalable purchasing, inventory, traceability, and logistics processes.

Lead end-to-end recruiting for engineers, scientists, operators, and other critical functions. Build sourcing channels, map technical communities, develop relationships with talent networks, define hiring criteria, design interview processes, manage recruiting operations and reporting, and oversee candidate engagement through onboarding. The role also includes building AI-enabled recruiting workflows and tools to improve sourcing reach and efficiency.

Develops electromechanical systems from architecture and mechanism design through prototyping, testing, manufacturing, and field deployment. Responsibilities include integrating actuators, sensors, controls, and software; troubleshooting mechanical, electrical, and software interfaces; creating SolidWorks designs, drawings, and build instructions; conducting system validation; resolving supplier and field issues; and incorporating operator feedback into design improvements.

Design, prototype, test, and deploy electronics for autonomous bio-detection systems. Responsibilities include PCB design and layout, mixed-signal circuits, power management, board bring-up and debugging, harness and connector design, lab testing, EMC considerations, and cross-disciplinary integration and field testing.

Design and manufacture ruggedized mechanical subsystems from concept to production: CAD modeling, prototyping (CNC, 3D printing, laser cutting, vacuum forming), microfluidic and airflow subsystem integration, DFM/DFA, tolerance analysis, testing, vendor coordination, field testing, and iteration toward production readiness.
