14h•$148,000 - $222,000

About The Position

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. The most meaningful work of your career is waiting. Join us. 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 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. About the Role: As an EMC Engineer on the Avionics Survivability team, you will perform electromagnetic compatibility (EMC) analysis, test, and verification of Avionics hardware on the Terran R launch vehicle per MIL-STD-461 and related standards. You will oversee EMC testing and qualification across multiple products through the entire product lifecycle from concept to flight maturity to include initial design consultation, emissions and susceptibility testing, design verification, qualification testing, and vehicle-level integration testing. You will work with cross-functional partner teams across the company to ensure Terran R's Avionics systems meet all EMC requirements and operate reliably in the harsh electromagnetic environment of launch and flight. A strong candidate for the role will have deep technical expertise in EMC testing methodologies, MIL-STD-461 requirements, and sound project management skills to ensure hardware is both compliant and on-schedule to support Terran R's launch!

Requirements

Bachelor's degree in Electrical Engineering, Physics, or a related field
5+ years of experience in EMC testing, analysis, and verification for mission-critical applications such as launch vehicles, spacecraft, aircraft, or defense systems
Technical expertise in MIL-STD-461 or equivalent test methods including conducted emissions (CE101, CE102), conducted susceptibility (CS101, CS114, CS115, CS116), radiated emissions (RE101, RE102), and radiated susceptibility (RS103)
Hands-on experience with EMC test equipment including spectrum analyzers, antennas, LISNs, current probes, signal generators, amplifiers, and shielded test facilities
Strong understanding of electromagnetic interference (EMI) principles, shielding effectiveness, grounding techniques, filtering, and cable design
Experience working with highly cross-functional teams (mechanical, thermal, electrical, software, systems) to develop integrated solutions for EMC compliance

Nice To Haves

Experience with additional EMC standards such as DO-160, MIL-STD-464, RTCA DO-160, or commercial standards (FCC Part 15, CISPR)
Familiarity with EMC simulation tools (CST, FEKO, HFSS, EMCoS) for pre-compliance prediction and design optimization
RF/microwave circuit design experience and understanding of antenna coupling and electromagnetic propagation
Experience establishing or managing EMC test facilities and developing test procedures
Knowledge of HIRF (High-Intensity Radiated Fields), lightning, and ESD testing requirements
