About Relativity Space
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. But that's just the start. 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 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. Now is a unique moment in time where it's early enough to leave your mark on the product, the process, and the culture, but far enough along that Terran R is tangible and picking up momentum.
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 a Senior Avionics Mechanical Engineer, you will own the design, development, and delivery of all mechanical hardware supporting our next-generation space science avionics platforms. This includes enclosures, mounting structures, thermal accommodations, and interfaces to spacecraft systems. You will be responsible for ensuring the delivered Avionics can survive launch and space environments, and for solving complex thermal and structural challenges in tight, mass-efficient packaging.
This is a hands-on role for a self-driven engineer who thrives in a fast-paced, prototype-heavy environment. You'll work from first principles to rapidly iterate on designs, perform analysis and testing, and lead the delivery of flight-ready avionics mechanical systems.
Our Commitment to Diversity and Inclusion
We are an equal opportunity employer and value diversity at our company. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.
