Sr Avionics Integration Engineer

Relativity Space•Long Beach, CA

6d•$132,000 - $181,500

About The Position

Relativity Space is building rockets to serve today’s needs and tomorrow’s breakthroughs. The Terran R vehicle will deliver customer payloads to orbit, meeting the growing demand for launch capacity. Joining Relativity means becoming part of something where autonomy, ownership, and impact exist at every level. Engineers solve problems that haven’t been solved before, helping develop a rocket, a factory, and a business from the ground up. Collaboration across teams, shaping decisions, and seeing work come to life in record time are key aspects of the culture. Creativity and technical rigor go hand in hand, and individual voices help define the stories being written together. This is an opportunity to leave a mark on the product, the process, and the culture, while Terran R is tangible and gaining momentum. 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. This role offers the chance to shape Terran R's fundamental avionics architecture and be given a high degree of ownership on components that will fly.

Requirements

Bachelor's degree in Mechanical Engineering, Electrical Engineering, Aerospace Engineering, or a related field
5+ years of experience in a full lifecycle design engineering role

Experience with the integration and test of complex, multi-disciplinary electrical systems

Nice To Haves

Proficiency with NX CAD and Teamcenter
Experience with Zuken E3 electrical design software
Experience with scripting and software development to support hardware bring-up activities (e.g. Python, LabView, C/C++)
Experience developing electrical and mechanical test fixtures, tools, and production harnessing
Experience working with hardware-in-the-loop (HIL or HITL) test systems

Responsibilities

Own the design, routing, and integration of electrical wire harnessing within the Terran R Avionics System from conception to qualification and production, including connectors, cable, and supports
Collaborate across various disciplines including structures, electrical hardware, propulsion, and software to optimize system-level avionics design through architecture trades and requirements definition
Utilize 3D modeling, 2D drafting, and electrical design packages to deliver detailed designs with considerations for production and test
Validate designs for flight through rapid prototyping and test campaigns
Support vehicle-level integration activities by defining avionics systems integration operations, checkouts, and test plans
