Sr Dynamics Engineer

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 Integrated Performance team owns the holistic view of how Terran R comes together, ensuring that every system on the vehicle and ground is capable of achieving our ambitious objectives. The team works across the full launch system, from trajectory design and aerodynamics to reliability analysis and beyond, with direct influence on all parts of the product lifecycle, from conceptual design to post-flight data review. Beyond analysis, team members engage hands-on with hardware and operations, with the mission and authority to drive meaningful programmatic change. With a unique organizational structure, the integrated performance team spans multiple technical domains and embeds directly with partner teams to solve the hardest multi-disciplinary problems. The team operates with a rare scale: large enough to support complex development, yet small enough that individual contributors have meaningful impact.As a part of the Integrated Performance group, the Loads & Dynamics team is directly responsible for digesting forcing functions and building models to produce loads for hardware owners and inform higher-level vehicle performance goals. The Loads & Dynamics team works heavily with partner teams in Aerodynamics, Guidance Navigation and Control (GNC), Propulsion, Structures, and Avionics to balance immediate hardware needs with updated analysis & modeling. About the Role: Develop random vibration and shock specifications and ensuring hardware across the vehicle is qualified to those specificationsOwn the dynamic loads for all hardware on Terran R from cradle-to-graveHelp mature hardware designs through keen understanding of mechanical structures fundamentals and effective, direct communicationBuild, validate, and document our analytical models to generate component load predictionsCollaborate with our partner teams to inform architecture decisions and deliver inputs for complex events like liftoff, stage separation, entry, and touchdownInform primary structure design and customer load inputs through Coupled Loads AnalysisAbout You: A bachelor’s degree or higher in engineering or related field5+ working experience with launch vehicles or rocketsDemonstrated experience driving dynamics issues to closure across mechanical, fluids or other domainsExperience with FEMAP and Nastran for dynamics model development, analysis, and post-processingFluency in Python, MATLAB, or similar programming languages for engineering analysisFamiliarity with statistics and data analysisNice to Haves, but Not Required: Experience with coupled loads analysis (CLA) or multibody dynamics (MBD)High-speed or modal data acquisition & signal processing experienceExperience with liquid rocket engines, launch vehicle analysis, or similar in aerospaceExperience with fluids/slosh modeling in coupled loads or other dynamic analysis frameworksExperience integrating payload and launch vehicle models for Coupled Loads AnalysisAt Relativity Space, we are committed to transparency and fairness in our compensation practices. Actual compensation will be determined based on experience, qualifications, and other job-related factors.Compensation is only one part of our total rewards package. Relativity Space offers competitive salary and equity, a generous PTO and sick leave policy, parental leave, an annual learning and development stipend, and more!
