Facilities Engineer

Relativity Space

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.

The Stennis Test team designs, builds, and operates Relativity's propulsion and stage test stands. Team members are hands-on with large-scale, complex systems including fully integrated engines and stage assemblies, pushing hardware to the limits and directly contributing to flight readiness. The work is fast-paced and highly operational, ideal for those with backgrounds in aviation, automotive, manufacturing, offshore operations, industrial systems, construction, or adjacent industries.

You'll work in a close-knit, dynamic environment where collaboration between technicians, operators, and engineers is not only encouraged, but expected. As the company scales, the Stennis Test team becomes even more critical to unlocking our next phase of growth: proving out full-stage systems and paving the way for routine, reliable flights of Terran R.

• Support facilities and infrastructure projects from field investigation and scope development through construction closeout.
• Develop scopes of work, technical requirements, cost estimates, drawings, and contractor bid packages with appropriate technical review.
• Review contractor proposals, drawings, submittals, schedules, and change requests for alignment with project requirements.
• Coordinate with contractors, vendors, technicians, NASA stakeholders, EHS, and internal partners throughout project execution.
• Conduct field observations during construction, document project status, help resolve routine issues, and escalate significant technical or scope changes as appropriate.
• Support testing, commissioning, punch-list completion, turnover documentation, and verification that completed work meets project requirements.

• Bachelor's degree in Mechanical Engineering, Electrical Engineering, Civil Engineering, Architectural Engineering, Facilities Engineering, Construction Management, or a related technical field; or equivalent combination of education, military service, training, and relevant experience.
• Experience through internships, co-ops, academic projects, military service, or professional work involving facilities, infrastructure, construction, utilities, manufacturing, or industrial systems.
• Foundational understanding of engineering principles and the ability to apply them to solve technical problems.
• Ability to gather and organize technical information, evaluate field conditions, and develop practical solutions.
• Ability to communicate technical information effectively, both verbally and in writing.
• Ability to work in a collaborative, fast-paced environment while managing multiple priorities.
• Ability to access and work in operational facilities, construction areas, rooftops, mechanical spaces, and outdoor environments as required to perform the essential functions of the role.
