Relativity
Senior Avionics Mechanical Design Engineer
Long Beach, California
About the Team 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 embedded with other functions such as propulsion, GNC, fluids, and stage engineering to ensure seamless integration and operation.
About the Role
Own the design, analysis, and test/validation of mechanical products within the Terran R avionics system, including electronics enclosures, vibration isolation, thermal management, and environmental protection devices.
Collaborate with electrical engineers to design robust, high‑performance printed circuit board assemblies.
Perform preliminary sizing for static and dynamic loads and thermal environments.
Utilize 3D modeling and 2D drafting packages to deliver detailed designs with considerations for production and test.
Validate designs for flight through rapid prototyping, analysis, and test campaigns.
About You
Minimum 5+ years of experience in a full‑cycle mechanical design engineering role.
Bachelor’s degree in mechanical engineering, aerospace engineering, or related field.
Experience with 3D computer‑aided design (CAD) software.
Experience with structural and thermal analysis.
Demonstrated project ownership and accountability on complex, multi‑disciplinary technical projects.
Nice to haves
Experience designing electronic assemblies, batteries, and/or vibration isolation systems.
Experience with finite element analysis methods.
Applied knowledge of geometric dimensioning and tolerancing (GD&T).
Proficient with NX/Teamcenter CAD package.
Compensation & Benefits Hiring Range: $138,000 - $178,000 USD.
In addition to competitive salary and equity, Relativity Space offers generous paid time off, sick leave, parental leave, an annual learning and development stipend, and more. For a full list of benefits, visit our benefits page.
