Avionics Hardware Engineer

Job Overview

At Relativity Space, we’re building rockets to serve today’s needs and tomorrow’s breakthroughs. Our Terran R vehicle will deliver customer payloads to orbit, meeting the growing demand for launch capacity. Achieving commercial success with Terran R unlocks new opportunities to advance science, exploration, and innovation.

The Avionics team is responsible for the full lifecycle of Terran R’s nervous system—designing, building, testing, installing, and operating the hardware that connects and controls every major electrical system on the vehicle and ground. Engineers are deeply embedded into other functions within Relativity, working closely with propulsion, GNC, fluids, and stage engineering teams to ensure seamless integration and operation.

As a Mixed‑Signal Hardware Engineer on the Avionics team, you will design, test, and analyze custom electronics for the Terran R launch vehicle. You will oversee hardware development through the entire product lifecycle from concept to flight maturity, including board bring‑up, design verification, qualification, initial flight production, integration, and vehicle operations. You will collaborate with cross‑functional partner teams across the company to help the team make the best possible decisions for the overall vehicle.

• Bachelor’s degree in Electrical Engineering, Computer Engineering, or a related field
• 8+ years of experience in electronics designed for harsh environments and mission‑critical applications such as launch vehicles, spacecraft, aircraft, or robotics
• Experience with eCAD software such as Altium or equivalent
• Experience with hardware bring‑up, validation, debugging, and data analysis
• Experience with board‑level design from concept to manufacturing
• Experience working with highly cross‑functional teams (mechanical, thermal, electrical, software, etc.) to develop integrated electronics solutions

• Familiarity with embedded software development and integration for avionics systems
• Experience with design for reliability and manufacturability of avionics hardware and systems
• Understanding of interfacing hardware such as sensors (thermocouples, pressure transducers) and electromechanical devices (solenoids, pyrotechnics, actuators)

Hiring Range: $189,000 - $241,000 USD

Competitive salary and equity, generous PTO and sick leave policy, parental leave, an annual learning and development stipend, and more.
