Job Description:

Job Description Job Description 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 Space pioneered large-scale additive manufacturing with our Terran 1 rocket, the largest 3D-printed object to fly. Now a distinct business unit within Relativity, Horizon Manufacturing Technologies is advancing next-generation manufacturing for aerospace and beyond. The team operates at the frontier of manufacturing innovation, where creativity meets capability. This is an environment where cutting-edge R&D is put into production, industrializing advanced manufacturing capabilities to solve customer problems. You'll work alongside welders, robotics engineers, data scientists, and systems engineers at the intersection of hardware and software, creating an end-to-end additive manufacturing platform that serves a wide variety of applications. From exploring new materials to unlocking faster print speeds, to designing complex, organic geometries that can't be built any other way, it's high-impact work that sets the foundation for the future of advanced manufacturing About the Role: The Robotics Team at Relativity Space is responsible for building and refining the hardware that powers our autonomous systems. From advanced perception and robotics for manufacturing and additive processes to specialized robots that support development and deployment, our R&D Software engineers work in close collaboration with hardware and automation to develop cutting edge technologies that push the boundaries of space exploration and industrial manufacturing. As a key member of the team, you'll bring your software expertise to revolutionize the way robotics cooperate and additively manufacture here on earth and off planet. Developing advanced methods for generating, evaluating, and ultimately printing complex novel geometries Developing custom software tools and algorithms for producing complex tool paths and valid multi-axis robot motion Working closely with simulation engineers and weld engineers to improve workflows between design CAD, distortion compensation, and printed metal results Contribute to occasional feasibility assessments to provide feedback and analysis on proposed new geometries from external partners or customers About You: BS in Computer Science, Architecture, Computational Design, or relevant field 3 years of experience developing tools for generating computational geometry Demonstrated experience in using scripting language to extend functionality of 3D software package (Python, C#, C++) Highly proficient in Rhino 3D & Grasshopper Understanding of CNC machine fundamentals and/or multi-axis robotic arms (KUKA preferred) Able to clearly articulate and communicate ideas, issues, and proposals effectively to a broad audience Experience with version control systems and collaborative development environments Nice to haves but not required: MS in either Computer Science, Architecture, Computational Design, or 5 years equivalent experience Direct experience with Autodesk PowerMill or similar motion machine control software Experience with path optimization for robotic manipulators Experience with 3D printing and/or WAAM process Experience programming motion for industrial robot arms At 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!
