About the role

Serve as the Subject Matter Expert (SME) for robot kinematics, motion modeling, and multi-axis synchronization.
PhD in Robotics, Control Systems, or a related technical field.

Our Terran R vehicle will deliver customer payloads to orbit, meeting the growing demand for launch capacity.
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.
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.
Experience developing software for real-time robotic systems.

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
Experience with ROS and open-source robotics libraries.
