Lead, Avionics Test Engineering Long , California

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 will unlock new opportunities to advance science, exploration, and innovation, pioneering progress that reaches beyond the known.

Joining Relativity means becoming part of a place where autonomy, ownership, and impact exist at every level. Here, you're not just executing tasks; you're solving problems that haven’t been solved before, helping develop a rocket, a factory, and a business from the ground up. Whether you’re in propulsion, manufacturing, software, avionics, or a corporate function, you’ll collaborate across teams, shape decisions, and see your work come to life in record time.

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. The team’s structure intentionally combines avionics design, manufacturing, and test to enable rapid iteration and feedback loops. 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.

Join us to shape Terran R's fundamental avionics architecture and take ownership of components that will fly.

• Lead a portion of the Avionics Test team, managing a team of test engineers and owning the design, development and implementation of fully automated test systems for Terran R electronics.
• Collaborate with cross‑functional partner hardware and software design teams in creating manufacturing test assets to complete acceptance and qualification testing.
• Coach individual engineers in technical and non‑technical best practices while fostering a culture of collaboration and high performance.

• Undergraduate or graduate degree (BS/MS/PhD) in Electrical Engineering, Computer Engineering, Computer Science, Aerospace Engineering, or a related field.
• 5+ years of experience with electronics hardware simulation, automation, and/or test.
• Experience leading engineers in best‑practices and domain‑specific technical principles.
• Ownership of complex test system design for motor drives, DC‑DC converters, load switches, high‑voltage DC electronics, and/or high‑voltage energy storage.
• Strategic planning, design, development, debugging, and maintenance of test systems in a production environment.
• Experience with environmental and qualification testing, including vibration, thermal, shock, and EMI/EMC validation.

• Schematic capture & PCB design tools such as Altium Designer.
• Analog sensors such as pressure transducers, RTDs, and accelerometers.
• Embedded software development and integration for avionics systems.
• Scripting languages such as Python or MATLAB for data acquisition/recording and analysis.
• Wire harness design.
• Familiarity with CAD tools such as NX.

Compensation is only one part of our total rewards package. Relativity Space offers competitive salary and equity, generous PTO and sick leave policy, parental leave, an annual learning and development stipend, and more.
