Come join HII!! Where Hard stuff is done right.

This opportunity resides within Uncrewed Systems (UxS), supporting advanced naval unmanned surface vessel (USV/MUSV) development, autonomy integration, and prototype test execution. We design, build, integrate, and test state‑of‑the‑art unmanned maritime systems for national defense and commercial partners.

Our team takes a comprehensive "cradle-to-grave" approach to every program-we don't just design; we develop, integrate, build, test, and deploy. Working within our collaborative, cross-functional environment, team members have unique opportunities to expand their expertise across multiple disciplines. We embrace a culture of shared ownership where everyone contributes beyond traditional boundaries, making this an ideal role for those who thrive on variety and continuous learning.

What you will be doing...

Performs routine naval architecture work requiring application of standard techniques, procedures, and criteria in carrying out a sequence of design and/or analyses of ship hull, foundation, superstructure, arrangements and hull form characteristics tasks. As directed, applies selected techniques and procedures to assignments involving ship design and ship performance analyses. Assists in the solution of difficult problems involved in areas of assignment. Uses prescribed methods to perform specific and limited portions of broader systems design, performance analyse, or hull form characteristic assignments of more experienced naval architects. The duties described herein cover major duties as required. However, this does not exclude the requirement of performing related duties under normal conditions, and other duties directed by supervision.

As a Naval Architect / Marine Engineer, you will provide engineering leadership and shipyard‑focused expertise across the design, construction, integration, and test phases of a Medium Unmanned Surface Vessel (MUSV) prototype program. Responsibilities include:

• Develop and/or review structural, weight, stability, hydrodynamic, maneuvering and seakeeping characteristics to ensure MUSV designs meet threshold performance requirements.

• Understanding of American Bureau of Shipping (ABS) standards and/or Navy Ship Design standards and/or USCG Rules. Applying rulesets to autonomous vessels.

• Translate MUSV SOW requirements into engineering products including specifications, interface documentation, design drawing reviews, and configuration baselines.

• Provide engineering oversight during shipyard construction or conversion activities-monitor progress, verify construction quality, and ensure alignment with approved design standards.

• Collaborate closely with autonomy, C2, electrical, and mechanical systems teams to ensure vessel design supports integrated unmanned operation requirements.

• Support development of test vessel descriptions, test plans, and engineering procedures required for MUSV prototype demonstrations.

• Participate in major milestone events including Post‑Award Conference, pre‑test inspections, and government witness events as required by the MUSV test plan.

• Support risk identification and mitigation related to design maturity, manufacturability, and shipyard workflow.

• Travel to shipyards, subcontractor facilities, government test sites, and partner locations as needed.

What we are looking for..

• 5 years relevant experience with Bachelors in Naval Architecture, Marine Engineering, Ocean Engineering, or closely related technical field; 3 years relevant experience with Masters in Naval Architecture, Marine Engineering, Ocean Engineering, or closely related technical field; or 0 years experience with PhD or Juris Doctorate in Naval Architecture, Marine Engineering, Ocean Engineering, or closely related technical field.

• 5+ years experience in shipyard construction, vessel design, or marine engineering; experience with commercial or naval craft strongly preferred.

• Working knowledge of ABS rules, ISO standards, and naval/marine classification requirements applicable to MUSV construction.

• Ability to interpret and develop engineering drawings, 3D models, test procedures, and technical data packages.

• Experience supporting or executing work inside active shipyards, including oversight of electrical, outfitting, configuration and mechanical installations.

• Strong verbal and written communication skills; ability to collaborate with multidisciplinary teams including autonomy, controls, software, test engineering, and supply chain.

• Ability to obtain and maintain a DoD security clearance.

• Willingness to travel (20-40%), including periodic shipyard and waterfront support.

Bonus Points for..

• Experience with unmanned surface vessels, autonomy integration, or advanced marine control systems.

• ABS class approval processes for novel or autonomous vessel designs.

• Experience performing or reviewing stability analyses, weight reporting, structural design, and hydrodynamic modeling.

• Familiarity with STANAG seakeeping environments, COLREGs-compliant autonomous vessel considerations, or unmanned system integration preferred.

• Experience with hull conversions, re‑powering, or refit programs applicable to MUSV conversion options.

• Familiarity with cyber‑resilient system design, technical data management, or RMF/SSP considerations for unmanned vessels.

• Prior participation in prototype testing, sea trials, or government‑observed evaluations.
