Job description

At Relativity Space, we’re building rockets to serve today’s needs and tomorrow’s breakthroughs. OurTerran R vehicle will deliver customer payloads to orbit, meeting the growing demand for launchcapacity. But that’s just the start. Achieving commercial success with Terran R will unlock newopportunities to advance science, exploration, and innovation, pioneering progress that reaches beyondthe known.

Joining Relativity means becoming part of something 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. Relativity is a place where creativity and technical rigor go hand in hand, and your voice will help define the stories we’re writing together. Nowis a unique moment in time where it’s early enough to leave your mark on the product, the process, andthe culture, but far enough along that Terran R is tangible and picking up momentum. The mostmeaningful work of your career is waiting. Join us.

About the Team:

The Interplanetary Sciences Program was established to expand access to scientific exploration across our solar system. Its mission is to make planetary research faster, more affordable, and more capable than ever before by rethinking how science missions are designed, built, and operated. The program aims to enable scientists to send instruments to distant worlds without decades of development or prohibitive costs. By creating a sustainable model for interplanetary exploration, we are transforming space science from an occasional event into a continuous process of discovery that accelerates knowledge, broadens participation, and inspires the next generation of explorers.

About the Role:

As the Staff Electrical Engineer within the Interplanetary Sciences Program, you will own the next generation ofdeepspace compute and storage capability byleveragingthe latest terrestrial technologies and challenging the status quo ofonboardcomputeand storage to other planets.

You willbe responsible fordesigning, building, and qualifyinghigh performancespacecraft electronicswithin the span of compute modules, network switches, storage nodes, andcommunications terminals. You will be working closely with the science team to maximize capability by balancing thecapability(CPU, GPU,storagecapacity, network bandwidth)with the technical constraints of the flight spacecraft (power, thermal, EMI, mechanical,reliability,etc…). This role will also work closely in conjunction with the software team tobring upthe core software infrastructure both on the spacecraft and on the groundside, anditerating with the software team to ensure the fullsystem elementsoperate as intended in all environments.

This role will be a high responsibility, high autonomy, and high accountability role within a fast-paced, iterative environment, where rapid prototyping, early testing, and continuous learning are key to success.You’lllead hands-on development campaigns to evaluate key technologies, derisk interfaces, andvalidateperformance before full system integration.You’llalso work across internal and external teams to turn concepts into hardware, balancingagilityand rigor as you move quickly from analysis to prototypes to flight-ready systems.

About You:

• Bachelor’s orMaster’s degree in Electrical Engineering, Physics, or a related technical fieldor equivalent experience.
• 5+ years designing and delivering high performance digital electronics
• Proven experience leading design,bringup, andvalidation ofsophisticated board level electronics
• Hands-on work with challenging thermal and electromechanical environments
• Excellent technical communication, problem-solving, and cross-disciplinary collaboration skills

Nice to haves but not required:

• Direct architecture or EE design experience with non-volatile storage, mobile compute, and/or server class computing is a plus
• Experience designingpower suppliesfor digital electronics, such as multi rail converters with strictsequencing requirements
• Experience with compute and storage survivability in space and radiation environments is a plus
• Strong grasp ofpracticalsystemsintegration and risk management in a development program
