Senior Project Engineer Jobs in Wiggins, MS (NOW HIRING)

About the Team:

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.

About the Role:

We are seeking a Senior Manager, Infrastructure 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 Terran R 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.

About You:

• Bachelor's degree in civil engineering, structural engineering, or a related technical discipline
• Minimum of 7 years of experience in the aerospace and/or construction industry, including a combination of field engineering and project management experience
• Experience with design documentation, construction drawings, bid solicitation, contractor selection, construction management, field supervision, permitting, QA/QC, and safety
• Experience in project scoping, budgeting, and scheduling at both the task and overall construction program levels
• Experience with architectural, structural, civil, and MEPF design, construction, and operations
• Knowledge of standard construction procedures, best practices, and means and methods
• Proficiency working within 3D models using NX, AutoCAD, or similar CAD software
• Experience with development permitting, land use controls, conditional use permits, and coordination with local government agencies

Nice to haves but not required:

• Strong written and verbal communication skills with the ability to interact effectively with internal and external stakeholders
• Demonstrated ability to work collaboratively in a team environment
• Experience independently driving projects while managing and reporting progress to remote leadership
• Strong organizational skills with the ability to manage multiple projects simultaneously
• Ability to read, develop, and interpret technical plans, drawings, blueprints, and models
