Background check, US Citizenship, CAC, and a confidential clearance are requirements for this position. Travel is 20%.
TMMG is seeking a Senior Naval Architect to support the Engineering Design Team (EDT) in delivering high-quality, execution-focused engineering solutions across commercial and naval shipbuilding programs. This role is not purely theoretical design. The right candidate understands how engineering translates to the deckplates - bridging design, production, testing, and delivery. You will be expected to step into active shipyard environments, resolve real-world engineering challenges, and ensure design products are executable, compliant, and aligned with ship construction and modernization efforts. This position supports both new construction and modernization programs, including NAVSEA, MSC, and commercial vessel platforms.
Requirements
Key Responsibilities1. Naval Architecture & Structural Engineering Execution
• Perform and lead structural and naval architectural analyses for ship systems, foundations, and modifications
• Conduct DDAM shock analysis, static and dynamic Finite Element Analysis (FEA), and load path evaluations
• Develop and validate shock-qualified designs for shipboard equipment and systems
• Ensure compliance with NAVSEA design practices, classification society rules (ABS), and contract requirements
2. 3D Modeling & Digital Engineering Integration
• Develop and manipulate 3D ship models using tools such as Rhino, SolidWorks, ShipConstructor, or equivalent
• Translate legacy drawings and incomplete data into accurate, buildable 3D models
• Support design-to-production alignment, ensuring models reflect real installation conditions
• Identify clashes, interferences, and constructability issues early
3. Technical Design Package (TDP) Development & Review
• Develop, review, and redline Technical Design Packages (TDPs) including:
o Drawings
o Calculations
o Reports
o Installation details
• Validate engineering products for technical accuracy and shipboard applicability
• Support Engineering Change Documents (ECNs/ECPs) and configuration control
4. Shipyard & Waterfront Integration
• Conduct ship checks, inspections, and onboard validation of systems and structures
• Work directly with production teams to:
o Resolve installation issues
o Address non-compliance conditions
o Eliminate rework and delays
• Act as the interface between engineering, production, and program stakeholders
5. Shock, Survivability & Compliance Engineering
• Lead or support DDAM shock analysis for mission-critical systems
• Evaluate shock mitigation strategies, isolation systems, and structural reinforcement
• Ensure designs meet shock, vibration, and survivability requirements
• Support resolution of shock trial deficiencies and non-compliance issues
6. Program & Technical Leadership
• Provide technical leadership and mentorship to junior engineers
• Support cross-functional coordination with:
o Shipyards
o Program offices
o Classification societies
o Government stakeholders
• Participate in technical reviews, design reviews, and risk assessments
Physical Job 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 or Marine Engineering from a recognized and accredited naval architecture program
(Mechanical Engineering degrees will not be considered for this role)
• 10+ years of experience in naval and/or commercial shipbuilding environments
• Demonstrated experience supporting NAVSEA, MSC, or major U.S. shipyards
• Strong background in ship structures, systems integration, and vessel design execution
• Ability to travel approximately % of the time
• U.S. Citizenship required; Active Secret Clearance preferred
Preferred Experience
• Experience supporting programs such as:
o LCS (Littoral Combat Ship)
o Aircraft Carrier (CVN) RCOH or new construction
o MSC auxiliary vessels
• Experience with:
o DDAM shock analysis and NAVSEA 3010 compliance
o FEMAP / Nastran or equivalent FEA tools
o Rhino 3D, SolidWorks, AutoCAD, ShipConstructor
• Background in:
o Ship modernization / overhaul programs
o Mechanical, hydraulic, or auxiliary systems integration
o Structural surveys and condition assessments
Key Competencies
• Strong understanding of shipbuilding execution and sequencing
• Ability to translate engineering into buildable solutions
• High attention to detail with practical problem-solving mindset
• Ability to operate independently in fast-paced shipyard environments
• Strong communication skills and able to work across engineering, production, and leadership teams
What Success Looks Like in This Role
• Engineering products are accurate, executable, and aligned with shipyard reality
• Reduced rework and field issues due to strong upfront engineering validation
• Rapid resolution of technical issues impacting production and testing
• Effective integration of design, construction, and test requirements
• Contribution to on-time vessel delivery and mission readiness
Why TMMG
TMMG is not a staffing firm - we are a shipbuilding execution integrator. Our engineers embed directly with shipyards and programs to solve problems early, reduce risk, and deliver results.
