Maritime Arrangements and Weights Lead

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 building a standardized nuclear electric plant — and the systems around it — to power maritime applications. We will install these plants on vessels built to our nuclear-ready standards, and we will move fast by leveraging the compact, proven technology of water-cooled reactors. Scaling atomic energy is the next chapter, and the open ocean is where we unlock it. We pioneer nuclear power at sea, tackling every step from design to deployment. 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 The Maritime Arrangements and Weights Lead commands the general arrangements, spatial allocation, and weight control frameworks of Ocean Atomics’ maritime systems design, driving the weight management and spatial engineering discipline required to secure class and regulatory approval for our fleet. While other structural and hydrodynamic parameters define the outer hull, this role owns the internal spatial footprint and mass distribution of the vessel. You will own the weight engineering matrices, center of gravity (CoG) tracking, compartmentation, and equipment envelopes from initial concept through operational deployment. Your primary directive is to enforce rigid weight, moment, and spatial margins to ensure our conventional platforms are natively pre-engineered for post-delivery nuclear integration. By delivering survivable, highly reproducible, and modular arrangements, you secure the critical spatial and mass equilibrium required to balance heavy nuclear payloads within marine structures, eliminating weight growth, center of gravity migration, and spatial interference risk across the entire operational lifecycle. Primary Responsibilities Command Spatial Allocation and General Arrangements: Lead the layout development, internal configuration, and space allocation of all compartments, matching operational profiles with strict marine accessibility standards. Own the Weight Engineering Framework: Architect, maintain, and defend the definitive weight engineering matrices and equipment envelopes across all active vessel design loops. Track Mass Equilibrium and CoG Migration: Execute precise center of gravity (CoG) tracking and moment calculations to ensure the platform remains stable throughout its construction, transit, and decades of operational life. Enforce Rigid Design Margins: Implement and safeguard strict weight, moment, and spatial margins to seamlessly accommodate heavy, highly localized nuclear containment payloads without requiring late-stage structural overhauls. Manage Compartmentation and Interference Resolution: Govern internal vessel compartmentation and drive cross-functional 3D spatial coordination to eliminate physical interferences between structural elements, routing lines, and machinery systems. Support Regulatory and Class Approvals: Produce formal weight summaries, deadweight survey procedures, and general arrangement drawings to satisfy classification society requirements and statutory maritime standards.

Qualifications

Education: Bachelor’s or advanced degree in Naval Architecture, Marine Engineering, or a strictly related marine systems design discipline. Experience: 8+ years of naval architecture experience, with a dedicated background managing weight control programs and general arrangements for complex commercial vessels or offshore energy infrastructure. Technical Mastery: Deep mastery of 3D CAD platforms (e.g., ShipConstructor, AVEVA Marine, Rhino) and professional weight tracking applications, coupled with an authoritative understanding of SNAME weight control guidelines and classification society rules. Leadership Posture: A meticulous, detail-oriented engineer who possesses unyielding discipline in data tracking, resolves spatial conflicts with analytical objectivity, and can firmly defend margin thresholds against cross-functional design pressures. Why this matters Every industry on Earth needs scalable, clean energy, and the ocean is the ideal place to unlock it. Joining Ocean Atomics means building real, lasting infrastructure — the kind that powers generations. The world needs abundant energy. Let's make it happen.
