Robotics Kinematics Engineer II

At Relativity Space were building rockets to serve todays needs and tomorrows breakthroughs. OurTerran R vehicle will deliver customer payloads to orbit meeting the growing demand for launchcapacity. But thats just the start. Achieving commercial success with Terran R will unlock newopportunities to advance science exploration and innovation pioneering progress that reaches beyondthe known.

Joining Relativity means becoming part of something where autonomy ownership and impact exist at every level. Here youre not just executing tasks; youre solving problems that havent been solved before helping develop a rocket a factory and a business from the ground up. Whether youre in propulsion manufacturing software avionics or a corporate function youll 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 were writing together. Nowis a unique moment in time where its early enough to leave your mark on the product the process andthe culture but far enough along that Terran R is tangible and picking up momentum. The mostmeaningful 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. As member of the Horizons Robotics Team youll work alongside welders data scientists and material scientists 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 cant be built any other way its high-impact work that sets the foundation for the future of advanced manufacturing.

About the Role:

We are seeking a Robotics Kinematics Engineer to join the Robotics team at Horizon with broad technical skills and a good balance between theoretical and hands-on mindset to develop and own a crucial backbone for our software infrastructure related with kinematics and calibration. 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.

• Develop advanced kinematics algorithms for robotic systems (6 DoF) including forward/inverse kinematics and redundancy resolution optimized for real-time performance.
• Own and maintain the kinematics library shared across multiple robotics software products.
• Develop and maintain calibration tools and methodologies supporting a wide range of robot calibration workflows.
• Serve as the Subject Matter Expert (SME) for robot kinematics motion modeling and multi-axis synchronization.

About You:

• BS required; MS preferred in Robotics Engineering Control Systems Engineering Computer Science or a related technical field.
• 3 years of experience developing kinematics algorithms for both underactuated and redundant robotic systems.
• Strong expertise in robot kinematic modeling and calibration methodologies using industrial metrology and localization hardware (Leica OptiTrack etc)
• High proficiency in C Linux and modern software engineering practices; comfortable developing in Python.
• Experience designing modular extensible software architectures that support diverse robot kinematics and configurations. Experience with ROS and open-source robotics libraries.

Nice to haves but not required:

• Experience with multi-robot coordination and synchronization.
• Experience with mobile manipulators.
• Experience developing software for real-time robotic systems.
• PhD in Robotics Control Systems or a related technical field.
