Staff Avionics Space Survivability Engineer

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: * Drive the development and test campaigns of avionics components and systems to ensure survivability across environments from ascent to orbit * Analyze and test failure mechanisms such as radiation effects, transient survivability, electromagnetic interference, and more * Develop and lead comprehensive test campaigns across a variety of environments for various components and subsystems * Assist in mentoring a team of multidisciplinary avionics engineers including RF/EMC, digital, power electronics, and avionics mechanical engineers About You: * Bachelors degree in Electrical Engineering, Physics, or a related field * 10+ years of experience in electrical design and testing * Demonstrated experience in design, modeling, simulation, and analysis of environmental effects such as radiation, high voltage transient, arcing, and electromagnetic survivability * Experience designing and qualifying space-based avionics hardware and failure investigations Nice to haves but not required: * Familiarity with test standards such as MIL-STD-461, SMC-S-016, etc.

* Experience in software programming and data analysis in tools such as C++, Python, and/or MATLAB
