Spacecraft Avionics Lead Engineer (Sonoma)

Spacecraft Avionics Lead Engineer

San Francisco Bay Area

A pioneering space company developing next-gen orbital mobility solutions is hiring an Avionics and Software Lead to own the full stack of spacecraft avionics and flight software for a new Spacecraft Development.

This is a rare opportunity to architect, build, and validate a complete flight system from scratch, working on cutting-edge propulsion-enabled platforms designed for responsive orbital manoeuvring.

In this role, you'll define the avionics architecture, lead integration of radiation-tolerant electronics, and drive flight software developmentincluding GNC algorithms, EPS design, and hardware-in-the-loop testing. Youll collaborate closely with cross-functional engineering leads to ensure spacecraft safety, autonomy, and reliability from concept through CDR.

This is a hands-on leadership role for someone excited by the challenge of building high-performance spaceflight systems in a rapid development environment .

What You'll Be Doing :

• Own the full avionics and flight software architecture through critical design review (CDR)
• Select and integrate COTS radiation-tolerant components for power, compute, and data handling
• Lead development of flight and ground software (telemetry, real-time control, fault management)
• Define and implement guidance, navigation, and control (GNC) algorithms
• Design electrical power systems (EPS), data bus architecture, and flight harnessing
• Build and operate a flat-sat HIL testbed for integration and validation
• Develop ICDs and maintain firmware / software configuration processes
• Support subsystem integration and testing campaigns
• Conduct FMEA and reliability analyses
• Lead subsystem design reviews and contribute to broader mission engineering milestones
