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

Design and integrate RF and hybrid RF/optical communication subsystems for space/airborne platforms. Develop SDR-based pipelines, high-speed free-space optical links, PCBA hardware, and test infrastructure. Perform system trade studies, validate end-to-end performance under real-world conditions, and collaborate with avionics, firmware, and compute teams for flight integration.

Lead end-to-end system integration and validation of electro-mechanical and avionics hardware. Design and build test infrastructure, develop automated and manual procedures, run environmental and functional tests, debug electrical systems, perform failure analysis, support flight qualification and launch readiness, and collaborate with hardware, firmware, and software teams to improve test coverage and reliability.

Design, build, and maintain spacecraft and ground software including flight software, simulations, mission control, and test tooling. Integrate and debug hardware-software systems, support on-orbit operations, and contribute to system architecture and launch preparation.

Coordinate interviews and candidate experience across technical, manufacturing, operational, and business teams. Manage complex scheduling, ATS hygiene, candidate communications, offer logistics, interview feedback, and onboarding support. Partner with recruiters and hiring managers to improve recruiting processes, reporting, and operational rigor during company growth.

Develop and maintain embedded firmware for spacecraft subsystems, implementing low-level drivers, communication protocols, real-time control, and fault-tolerant features. Support board bring-up, hardware integration, HIL testing, automated validation tools, and cross-disciplinary debugging and anomaly investigations throughout development and on-orbit operations.

Design, model, and analyze spacecraft propulsion fluid systems including propellant storage, transfer, pressurization, and thermo-fluid behavior. Perform CFD and thermo-fluid modeling, sizing and trade studies, supplier evaluation, test planning, and verification while collaborating with propulsion, mechanical, GNC, and systems teams.

Own end-to-end purchase order lifecycle and supplier management for complex engineered hardware. Negotiate vendors, mitigate risk, manage procurement workflows and compliance, and drive cost-savings. Build data-driven sourcing tools and dashboards (SQL/Python/BI), automate processes, and partner cross-functionally with engineering, finance, and operations to support hardware development and production timelines.
