Job Description
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 deeply embedded into other functions within Relativity, working closely with propulsion, GNC, fluids, and stage engineering teams to ensure seamless integration and operation. Now is a unique time to join: you'll get to help shape Terran R's fundamental avionics architecture and be given a high degree of ownership on components that will fly.
About the Role:
- Own the design, analysis, and test/validation of mechanical products within the Terran R avionics system. Mechanical products include 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 of 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 with complex, multi-disciplinary technical projects
Nice to haves but not required:
- Experience with the design of 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
