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:
We are seeking a Senior Software Engineer with broad technical skills and a hands-on mindset to develop and own the crucial backend software infrastructure that connects robotics software, data platform, machine learning, and digital twin of our Stargate autonomous additive manufacturing platform. This role is ideal for a software engineer who thrives in cross-functional environments, enjoys owning full projects from design to deployment, and is comfortable navigating ambiguity in a fast-moving R&D setting.
You’ll contribute to the core software infrastructure that connects edge hardware, ML inference systems, real-time process monitoring tools, and visualization platforms. You'll work closely with robotics, data, ML, and infrastructure engineers to develop clean, reliable, and maintainable software that integrates tightly with hardware and real-world processes.
- As a member of Horizon's Data Platform team, you'll develop user-facing applications, APIs, and Create/Read/Update/Delete services that expose data platform capabilities to end users
- Create backend services that integrate with data architectures and enable data consumption
- Develop frontend interfaces for data visualization, analytics, and platform management
- Deploy and maintain software in both edge and cloud environments
- Collaborate with robotics software engineers to integrate your software with the robotic operating system
- Contribute to internal tooling that improves developer productivity and system observability
About You:
- 5+ years of professional software engineering experience
- Experience developing and shipping production-quality software with real-world operational constraints
- Proficient in whatever languages and tools you love most, and willing to learn new ones
- Ability to independently identify, scope, design, and execute software projects
- Understanding of databases, pipelines, and platforms, and how to write software that interacts with them
- Experience designing in collaboration with non-software stakeholders
Nice to haves but not required:
- Experience developing software for robotics or additive manufacturing applications
- Familiarity with Robot Operating System (ROS)
- Prior experience in a small company or startup where you owned software end-to-end
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! To see some of the benefits & perks we offer, please visit here.
We are an equal opportunity employer and value diversity at our company. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.
