Senior Avionics Engineer, Lunar

Headquartered in Long Beach, California, and with more than 1,000 employees and over a billion dollars in private capital, Vast has built the facilities required to manufacture and operate America’s next space station. The company plans to develop future habitats and systems for the Moon and Mars, dedicated space stations for government partners, and other crewed systems that will unlock the expanding long-term space economy.

Vast is looking for a Senior Avionics Engineer to support our Lunar Program, reporting to the Senior Vice President, Lunar Programs. As the first dedicated avionics engineer on the program, you will serve as a Responsible Engineer for flight avionics hardware, owning design, development, qualification, and integration from early architecture through flight. You will help define how the Lunar program builds avionics: setting the architecture, design standards, and verification practices that the team will inherit as the program scales.

This will be a full-time, exempt position located in our Long Beach location.

Responsibilities:

• Serve as Responsible Engineer for avionics subsystems and components, owning requirements, design, analysis, build, test, and flight readiness
• Define and develop avionics architecture for lunar vehicles and systems, including flight computers, power distribution, data handling, communications, sensors, and harnessing
• Design and develop flight electronics, including schematic capture, PCB layout oversight, component selection, and box-level design, with attention to radiation, thermal, and environmental constraints beyond LEO
• Write and manage avionics requirements and interface control documents, and work closely with GNC, flight software, propulsion, power, thermal, and structures teams to close interfaces
• Lead design reviews (CoDR, PDR, CDR) and present technical trades, analyses, and risks to program and engineering leadership
• Plan and execute development, qualification, and acceptance test campaigns for avionics hardware, including functional, EMI/EMC, random vibration, shock, thermal cycling, and TVAC testing
• Build and maintain avionics test benches, hardware-in-the-loop setups, and ground support equipment for checkout and integration
• Support integration of avionics into vehicle-level systems, and troubleshoot hardware, firmware, and interface issues through integrated testing
• Partner with suppliers on procurement, design reviews, and acceptance of avionics components and assemblies
• Drive reliability, parts selection, derating, and failure analysis practices, and own corrective actions on non-conformances
• Help scope and grow the Lunar avionics team, mentoring engineers and technicians as new hires join

Minimum Qualifications:

• Bachelor’s degree in Electrical Engineering, Computer Engineering, or a related engineering discipline
• 6+ years of experience designing, developing, and testing avionics or electrical hardware for aerospace, defense, or similarly demanding applications
• Demonstrated ownership of hardware from design through test and integration

Preferred Skills & Experience:

• Experience serving as Responsible Engineer for spaceflight avionics through qualification and flight
• Experience with embedded systems, flight computers, power electronics, and data bus architectures (e.g., RS-422, CAN, SpaceWire, Ethernet, MIL-STD-1553)
• Experience designing for radiation environments, including part selection, single-event effects mitigation, and total ionizing dose considerations for beyond-LEO or lunar missions
• Proficiency with schematic capture and PCB design tools (e.g., Altium) and the ability to read and interpret schematics, harness drawings, and interface documentation
• Experience with environmental and EMI/EMC testing for spaceflight hardware
• Experience with coding languages (Python, C/C++, MATLAB) for test automation, firmware support, and data analysis
• Experience standing up new hardware capability, labs, or teams in a fast-paced, resource-constrained environment
• Demonstrated experience mentoring or leading engineers and technicians, formally or informally
• Ability to work in multi-disciplinary teams and operate independently with limited direction, thriving in a fast-paced, rapidly changing environment

Additional Requirements:

• Willingness to travel to test sites, including Mojave and supplier or outside test facilities, as required
• Willingness to work evenings and/or weekends to support critical mission milestones

Pay Range: California

$147,000—$249,000 USD
