Senior Structural Analysis Engineer, Tools & Methods

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:

Relativity's Integrated Performance teams ensure that our products work across all systems and disciplines, from trajectory design to aerodynamics to reliability analysis and beyond. Our groups size the Terran R rocket, design its missions for customer success, reliability, and reusability, and ensure that every system on the rocket and ground is engineered correctly for the demanding environments of launch and entry. Recently, we completed the preliminary design and analysis of Terran R including Relativity's first-ever work on launch vehicle reusability, spanning advanced trajectory simulations, wind tunnel testing, and structures analysis, among many other projects.

The Integrated Analysis group is responsible for accelerating Relativity's hardware engineering via advanced analysis and cutting-edge tools. The team works on a variety of complex structures analyses across all of our hardware teams, and develops tools and methods to unlock deeper insight in less time - to reduce weight, improve robustness, and deliver more flight-ready hardware to the launch pad.

About the Role:

• Mature Relativity's structures analysis processes, including custom and commercial tool selection and implementation, workflow automation, methodology development, and data and results processing, storage, and communication
• Develop intuitive interfaces for hand calculations, linear/nonlinear FEA, and test data, gathering families of data across test and analysis cycles, comparing data against predictions, etc.
• Work closely with dynamics and other disciplines to develop tools for load combination and interdisciplinary environments mapping
• Integrate processing and analysis tools written by structures engineers into larger organizational software frameworks
• Develop front-end interactive visuals for mapping data and analysis outputs through vehicle locations, flight timelines, etc.

About You:

• Undergraduate degree in engineering or related field
• 5+ years experience in numerical analysis and tool development, preferably for FEA, CFD, or finite volume thermal analysis
• 2+ years of experience software development in a data handling/interdisciplinary environment
• Experience solving complex problems on integrated vehicles
• Experience structuring, negotiating, executing, and delivering complex tools and methods projects from start to finish
• Proficiency in Python and version control systems (e.g., git)

Nice to Haves, but Not Required:

• Graduate degree in engineering or related field
• 8+ years relevant experience
• Experience managing and developing analysis toolsets and workflows across in-house and commercial software
• Experience developing and managing robust data pipelines (storage backends, processing, front ends / GUIs)
• Familiarity with classical aerospace sizing methods (Timoshenko, Bruhn, Roark, etc);
• Expertise in multiple technical domains (e.g. structural and thermal)
• Familiarity with fatigue and damage tolerance analysis
