Responsibilities

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

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 leverages close partnership between 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.
