Job description

Principal / Senior Principal Mechanical Engineer

Annapolis, MD | Onsite | Secret Clearance Required

Design hardware that goes where most engineers never get to work.

We are looking for a Principal or Senior Principal Mechanical Engineer to support the development of advanced naval and undersea systems in Annapolis, MD.

This is a hands‑on engineering role for someone who enjoys taking a problem from concept → design → manufacturing → testing → integration.

What You’ll Do

• Develop mechanical concepts and solutions for complex undersea hardware
• Translate customer and system requirements into practical mechanical designs
• Design and integrate mechanical components and assemblies
• Work with manufacturing teams to ensure designs can actually be built
• Develop engineering drawings, processes, procedures, and manufacturing documentation
• Apply GD&T and sound design‑for‑manufacturing principles
• Support prototype and low‑to‑medium volume production
• Participate in hardware testing, troubleshooting, and integration
• Solve difficult technical problems while balancing performance, schedule, cost, and manufacturability
• Work closely with other engineers, manufacturing, program teams, and customers

What We’re Looking For

• BS in Mechanical, Aerospace, Ocean Engineering, or related STEM field + 5 years of experience
• OR MS + 3 years of experience
• BS + 8 years of experience
• OR MS + 6 years
• OR PhD + 4 years
• Strong mechanical hardware design experience
• Experience taking requirements and turning them into engineering solutions
• Understanding of manufacturing and production processes
• Strong problem‑solving and communication skills
• Experience with common engineering design and analysis tools
• Ability to obtain TS/SCI with CI Poly
• Ability to work onsite in Annapolis, MD

Nice to Have

• Teamcenter
• GD&T
• Undersea vehicle or naval systems experience
• Experience designing hardware for demanding environments
• Active TS/SCI with CI Poly

Why This Role?

This isn’t a CAD-only position. You’ll be involved in the engineering decisions behind complex hardware and have the opportunity to see your designs move from an idea into a real system.

If you enjoy solving hard mechanical problems, working with hardware, and owning designs from concept through testing, this could be a great fit.
