Senior Controls Engineer: Optical Beam Pointing Mars

Long Beach, California, United States

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 beyondthe 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. Nowis a unique moment in time where it’s 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 most meaningful work of your career is waiting.

About the Team:

The Interplanetary Sciences Program was established to expand access to scientific exploration across our solar system. Its mission is to make planetary research faster, more affordable, and more capable than ever before by rethinking how science missions are designed, built, and operated. The program aims to enable scientists to send instruments to distant worlds without decades of development or prohibitive costs.

By creating a sustainable model for interplanetary exploration, we are transforming space science from an occasional event into a continuous process of discovery that accelerates knowledge, broadens participation, and inspires the next generation of explorers.

About the Role:

As a Senior Controls Engineer within the Interplanetary Sciences Program, you will be the technical lead for optical beam pointing and control systems that enable high-precision optical communications for our 2028 Mars Orbiter mission. You will design, develop, and implement the control algorithms that measure the subsystem orientation using advanced sensor fusion and actively steer both spacecraft attitude and beam orientation to maintain precision optical links across interplanetary distances.

This role requires end-to-end technical ownership of a mission-critical control system that integrates optical sensors, gyroscopic measurements, spacecraft attitude control, and fast steering mirror systems. You will develop engineering methods, control architectures, and flight-ready algorithms that enable the spacecraft to acquire, track, and maintain optical beam pointing while rejecting spacecraft jitter and environmental disturbances.

You will work across communications, GNC, flight software, and spacecraft systems teams to ensure the optical beam pointing system meets performance requirements from design through prototyping, ground testing, launch, cruise, and orbital operations at Mars.

What You’ll Do:

• Own the design, development, and implementation of optical beam pointing and control algorithms for the 2028 Mars Orbiter mission.
• Develop control systems that integrate optical sensor measurements, gyroscopic data, and spacecraft attitude estimates to achieve precision beam pointing and tracking.
• Design and implement fast steering mirror control algorithms that reject spacecraft jitter and maintain optical link performance during dynamic conditions.
• Develop sensor fusion…
