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.\nJoining 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.\nAbout the Team:\nThe Propulsion team at Relativity is focused on developing and delivering highly performant and manufacturable engines for Terran R. Engineers are responsible for the entire lifecycle of their parts, from initial design through production to qualification and flight. The team fosters a culture of bottoms-up decision-making, free from technical gatekeeping, where ownership and accountability are key at all levels. But designing engines with a quarter million pounds of thrust is just the beginning. As the flight configuration enters qualification, the team is now exploring modifications for future engines, including thrust upgrades, new cycles, and design for mass production.\nAbout the Role:\nAs an Engine Design Responsible Engineer you will be responsible for owning top-level engine CAD models. Depending on the phase of the program and the engine configuration that you are owning, this role will entail:\nLead CAD release and configuration control for production engine assemblies, ensuring accurate eBOM structures and smooth downstream integration\nOwn engine layout and packaging trades, including definition of Keep-in-Zone (KiZ) and Keep-out-Zone (KoZ) boundaries\nDesign and analyze Integrated Design hardware (fluid manifolds, tubing, ducting, secondary structures) and execute rapid design tweaks to support engine testing\nDefine engine assembly tolerances/requirements as defined on Interface Control Diagrams (ICDs.) - Establish and standardize best practices across the Propulsion organization for things like fittings, bolts, seals, etc.\nChampion the change management process and help continuously improve it. - Own tracking of key engine metrics, like mass and part count\nPartner with the Integration/Manufacturing team by reviewing and continuously improving Process Plans, Work Orders, and Non-Conformances\nStrive to set downstream stakeholders up for success by enabling increased engine build rates and quality. Provide floor support at times to resolve build issues\nAbout You:\n2+ years of professional design experience\nBachelor's degree in an engineering field\nDemonstrated project/technical leadership skills\nStrong understanding of engineering fundamentals in structures, fluids, thermal, and mechanisms\nCAD skills (any platform)\nExperience with large CAD model management, change management, and configuration management\nExperience designing Integrated Design hardware (manifolds, secondary structure, tubing, etc.)\nAttention to detail, thorough, exhibits strong follow-through. Understands the critical importance of a flawless eBOM that sets downstream stakeholders up for success\nGreat Integration/Manufacturing partner. Experience with any Manufacturing Execution System (MES.) Addresses DFA/DFM feedback in a timely fashion to set production up for success\nNice to haves, but not required:\nExperience with Siemens NX and Teamcenter, specifically\nExperience in the design of liquid propulsion components and systems\nExperience with Finite Element Analysis (FEA) and commercial tools such as Ansys, Abaqus, or Nastran\nFamiliarity with aerospace standards (AS, NAS, SAE, etc.)\nExperience with creating release, mass, and part count reports. Ability to communicate this information to leadership and stakeholders in a clear and concise manner\nFamiliarity with Qualification and Acceptance test requirements for flight hardware\nWe are an equal opportunity employer and value diversity at our company.
