Naval Architecture Arrangements and Weights Lead

Ocean Atomics

12d • $150,000 - $200,000

About The Position

The ocean is the largest undeveloped frontier on earth — and the next chapter of abundant energy will be written at sea. We're building the infrastructure to power it.
About Ocean Atomics (OA)
Ocean Atomics is an American company designing, licensing, and assembling a standardized nuclear electric power plant and the surrounding support systems for maritime applications. We will install these plants on any vessel built to our nuclear-ready standards, and will provide end-to-end sustainment in our planned nuclear lifecycle dockyard. We will help develop the licensed operators to unlock this new capability for your energy intensive application at sea. To move fast and to lead the creation of this new market, we are leveraging the compact, proven systems enabled by water-cooled reactors.
Our mission
Scale nuclear energy. Power generations.
Our vision
A maritime commons thriving with abundant, economical, modern, and safe nuclear-powered activity — built, serviced, and staffed by re-industrialized American shipyards and people.
Role Summary
As the Naval Architecture Arrangements and Weights Lead, you lead the general arrangements, spatial allocation, and weight control for the vessels that carry Ocean Atomics' nuclear electric plant. While naval architecture defines the outer hull, you're responsible for the internal spatial footprint and mass distribution: the weight engineering matrices, center of gravity tracking, compartmentation, and equipment envelopes, from concept through deployment. The margins you hold are what let our plant integrate into the vessel cleanly without late-stage structural rework, and keep the vessel stable across decades of operation.
The ideal candidate treats weight and margin discipline as the quiet foundation of a safe design rather than box-checking, and can hold a threshold under design pressure without turning a review into a standoff.

Requirements

• Bachelor's or advanced degree in Naval Architecture, Marine Engineering, or a related marine systems discipline, or equivalent practical experience.
• Track record leading weight control programs and general arrangements for complex commercial vessels or offshore energy infrastructure, from concept through class approval. Typically built over 8+ years in naval architecture. Depth of experience and successful weight and arrangement programs is valued above years of experience.
• Working command of 3D CAD platforms (ShipConstructor, AVEVA Marine, Rhino, or equivalent) and weight-tracking tools, with knowledge of SNAME weight control guidelines and classification society rules.

Nice To Haves

• Experience with highly regulated vessel classes or offshore energy structures.
• Familiarity with balancing heavy, concentrated mass items within marine structures.
• Cross-functional experience partnering with structures, propulsion, and hydrodynamics teams on integrated designs.
• International regulatory experience (IMO, foreign flag states).

Responsibilities

• Lead general arrangements and space allocation across all compartments, matching operational profiles to marine accessibility and egress standards.
• Build and maintain the weight engineering matrices and equipment envelopes across active design loops, keeping a single source of truth for mass as the design evolves.
• Track center of gravity and run moment calculations so the vessel holds stability through construction, transit, and decades of operation.
• Hold the weight, moment, and spatial margins that let our nuclear electric plant integrate into the vessel without late-stage structural overhauls.
• Drive 3D spatial coordination with the structures, propulsion, and routing teams to resolve interferences between structural elements, machinery, and distribution systems before they reach the shipyard.
• Produce the weight summaries, deadweight survey procedures, and general arrangement drawings that clear classification society (ABS, LR, etc.) and flag state (USCG, etc.) reviews.
