Marcurius Multi-Mission Solutions is a fast-growing Defense technology company headquartered in Clearwater, Florida. Founded by US and UK veterans, Marcurius brings decades of frontline experience across Special Operations and Intelligence missions, with deep expertise in asymmetric warfare and the real-world employment of unmanned systems.

Marcurius is building a new kind of unmanned systems company- multi-domain, multi-platform, and mission-driven. We fuse battle-proven technologies, resilient command-and-control architectures, and operator-led doctrine to deliver capabilities that work in contested environments. Our initial focus is the rapid fielding of advanced Unmanned Surface Vessels (USVs) for modern maritime operations.

Marcurius is developing multiple unmanned surface vessel classes, including high-speed monohulls and multihull catamarans. We are seeking a Marine Systems Engineer to serve as the internal technical authority for hull platform evaluation, integration, and design validation across all craft.

This role is responsible for reviewing, challenging, and owning hull-level design decisions. You will ensure that vendor-delivered designs meet structural, hydrodynamic, and integration requirements — and that platform decisions support both prototype success and future manufacturability.

You are not only designing or reviewing hulls - you are responsible for making sure they work in the context of the full system.

• Own technical evaluation of all hull platforms across multiple craft classes, identifying risks, gaps, and non-compliances in vendor designs
• Review and challenge naval architecture deliverables including stability analyses, structural design, accommodation layouts, and resistance/powering calculations
• Define and enforce accommodation requirements for propulsion systems, payloads, sensors, antennas, and access across all vessels
• Ensure hull designs support full system integration, coordinating closely with electrical, autonomy, and mission systems leads
• Provide design-for-manufacturing input, ensuring hull geometry, structure, and sectioning align with 3D printing and assembly strategy
• Evaluate structural loading conditions and validate designs against real operating environments, including payload effects and dynamic loads
• Define platform-level acceptance criteria in coordination with Test & Evaluation
• Assess and document operational limits of each hull class, including sea state, speed envelope, and stability constraints
• Drive decisions where vendor recommendations conflict with system-level requirements

• Degree in naval architecture, ocean engineering, marine engineering, or related field
• 5+ years of experience in marine platform design or design review
• Demonstrated experience with multihull or catamaran design (required)
• Strong ability to review and evaluate stability analyses, structural drawings, and accommodation plans
• Experience working with naval architecture tools such as Maxsurf, Rhino, Ship Constructor, or equivalent
• Experience reviewing and challenging third-party or vendor design work

• Experience with unmanned or autonomous marine platforms
• Familiarity with additive manufacturing or composite fabrication methods
• Defense or military maritime program experience
• Knowledge of classification society standards (ABS, DNV, Lloyd’s, etc.)
• Experience designing for maintainability in uncrewed environments

This role ensures Marcurius is not dependent on vendor judgment for platform-critical decisions. The right person will protect hull integrity, integration quality, and manufacturability across all vessel classes, preventing design issues that are costly or impossible to fix later in the program.

• Ability to work onsite in shipyard, fabrication, and marine…
