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 Horizon's Robotics Team, you'll 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 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 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.
