• Familiarity with Navy, USCG, and classification society standards (e.g., ABS, DNV).
• Excellent technical writing, reporting, and communication skills.
• Strong understanding of hydrodynamics, hydrostatics, weight estimation, stability analysis, and structural design methods relevant to manned and unmanned maritime platforms.
• Proficiency in interpreting and generating technical drawings, design specifications, and simulation outputs.

Preferred Requirements

• Professional Engineer (PE) license in naval or marine engineering.
• Experience supporting DoD maritime R&D and acquisition programs.
• Familiarity with open architecture design, modular payload integration, and vehicle control systems.
• Experience integrating unmanned or autonomous maritime systems.
• Knowledge of digital engineering, simulation-based design, and survivability modeling best practices.

Physical Demands

The majority of the time is spent in an office setting. Occasionally lift and/or move up to 25 pounds. Specific vision abilities required include close vision, distance, vision, color vision, and ability to adjust focus.
