Senior Manager, Civil Engineering

Introduction

At Relativity Space, we’re building rockets to serve today’s needs and tomorrow’s breakthroughs. Our TerranR vehicle will deliver customer payloads to orbit, meeting the growing demand for launch capacity. Achieving commercial success with TerranR will unlock new opportunities to advance science, exploration, and innovation.

Joining Relativity means becoming part of a culture where autonomy, ownership, and impact exist at every level. You’ll solve problems that haven’t been solved before, help develop a rocket, a factory, and a business from the ground up, and see your work come to life in record time.

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 – 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.

Collaboration between technicians, operators, and engineers is not only encouraged, it’s expected.

We are seeking a Senior Manager, Civil Engineering to join our team at the Stennis Space Center in Mississippi. In this role, you will lead the development, design, engineering, and construction of TerranR test infrastructure, helping deliver next‑generation test stands and facilities.

As part of the Test Infrastructure organization, you will coordinate cross‑functional technical teams to define architectural, structural, civil, electrical, mechanical, plumbing, fire protection, and industrial requirements. You will serve as the owner’s representative with external consultants, contractors, and regulatory agencies, while partnering internally with Infrastructure, Test Operations, and Vehicle teams to develop project designs, budgets, and schedules.

You will manage construction documentation, RFPs, bidding and evaluations, subcontractor selection and oversight, and on‑site construction management to ensure projects are delivered on schedule and within budget. This role requires strong experience in field and construction engineering, project management, and the ability to independently drive complex projects from concept through execution. Up to 25% travel is expected to support design, construction, testing, and operations across Relativity sites.
