Description
Salary: $90,000 - $110,000
Background investigation, US Citizenship, CAC, and a confidential security clearance are requirements of this position. Travel is 20%.
TMMG is seeking a Senior Structural Engineer to support the Engineering Design Team (EDT) in delivering high-impact engineering solutions across naval and commercial shipbuilding programs.
This role is not a traditional "desk-only" design position. The selected candidate will operate as a hands-on technical leader, bridging engineering, production, and waterfront execution. The engineer will be expected to solve real shipyard problems, validate designs against actual installed conditions, and ensure structural solutions support constructability, test readiness, and delivery schedules. The ideal candidate brings deep experience in ship structures, strong analysis and design capability, and the ability to operate effectively in fast-paced, multi-discipline environments.

1. Structural Design & Analysis
• Develop and review structural designs for:
o Hull structures, foundations, and reinforcements
o Equipment foundations (shock, vibration, and mission systems)
o Deck structures, bulkheads, and support systems
• Perform structural calculations and analyses, including:
o Static and dynamic loading
o Fatigue and stress analysis
o Shock and vibration (DDAM / Navy shock requirements preferred)
• Ensure compliance with:
o ABS, USCG, NAVSEA, and applicable classification rules
o Contract specifications and regulatory requirements
2. Shipyard & Waterfront Integration
• Interface directly with:
o Production teams
o Planning and scheduling
o Test & Trials teams

o Design gaps impacting production
o Interferences and constructability issues
• Support deckplate problem-solving to keep work moving
3. Engineering Change & Configuration Control
• Review and develop:
o Engineering Change Notices (ECNs)
o Work Orders and field changes
• Assess impacts to:
o Structure integrity
o Schedule and sequencing
o Material and installation
• Ensure structural changes are:
o Technically sound
o Buildable in the shipyard environment
4. Shock, Load & Specialty Analysis
• Perform or support:
o Equipment mounting and foundation design
o Load path verification and structural adequacy
• Support customers with:
o Analytical assessments
o Data requirements definition
o Technical reporting and recommendations
5. Drawing Development & Review
• Develop and review:
o 2D drawings and structural details (AutoCAD or equivalent)
o 3D model outputs (Navisworks, ShipConstructor, or similar)
• Ensure drawings:
o Reflect real installation conditions
o Support production sequencing
• Align with configuration control requirements
6. Client & Program Support
• Interface with clients, including:
o Shipyards
o Government representatives (NAVSEA, USCG, MSC)
o OEMs and vendors
• Provide:
o Technical recommendations
o Clear, actionable communication
• Support proposal efforts and technical write-ups when needed
7. Mentorship & Leadership
• Provide technical guidance to:
o Junior engineers
o Designers and drafters
• Establish best practices for:
o Structural design and analysis
o Shipyard integration
• Serve as a go-to technical authority within EDT
Physical Requirements
• Prolonged periods sitting at a desk and working on a computer.
• Must be able to lift up to 15 pounds at a time.
• Must be able to access and inspect all areas of machinery.
Education/Certification Requirements
Bachelor's Degree in:
• Naval Architecture, Structural Engineering, or Mechanical Engineering (with structural focus)
• Master's Degree preferred
Experience
• 10+ years of experience in:
o Naval or commercial shipbuilding
o Structural design and analysis
• Proven experience supporting:
o Shipyard construction or waterfront execution
• Experience with:
o ABS, USCG, and/or NAVSEA standards
Technical Skills
• Strong proficiency in:
o Structural analysis methods and calculations
o AutoCAD (required)
o 3D modeling tools (preferred)
• Experience with:
o Shock analysis (DDAM preferred)
o Finite Element Analysis (FEA tools such as FEMAP, ANSYS, NX-NASTRAN, etc.)
• Ability to:
o Interpret and develop technical drawings
o Translate engineering into buildable solutions
Preferred Qualifications
• Professional Engineer (PE) license
• Experience on programs such as:
o Naval vessels (DDG, LCS, OPC, MSC vessels)
o Offshore or commercial vessels
o Familiarity with:
o Configuration management systems
o Test & Trials processes
o Experience working in:
o Multi-shipyard or multi-program environments
Key Competencies
• Execution-Focused Mindset
• Understands that good engineering must work in the yard
• Problem Solver at the Deckplate Level
• Integrator
• Bridges engineering, production, and testing seamlessly.
• Schedule-Aware Engineer
• Understands how structural decisions impact cost and delivery timelines.
• Clear Communicator
• Can explain complex structural issues in plain language to all stakeholders.
Why TMMG
At TMMG, we don't just design-we integrate, execute, and deliver. Our engineers are embedded with clients, solving real problems that impact schedule, cost, and vessel delivery.
