Intern Offshore Subsea Engineer Jobs (NOW HIRING)

Location: New York, NY or Remote (U.S.). Remote candidates are welcome to apply.

Role Description

You will develop the platform's underwater mechanical, structural, installation, retrieval, and marine-interface systems, working across the lifecycle rather than inside one specialty. We are looking for a solid foundation in one subsea or offshore discipline plus the appetite to follow a module through transport, installation, seabed support, connection, inspection, intervention, and retrieval.

You are not expected to be a specialist in every discipline listed below, and you will work under the technical direction of senior engineering leadership. You are expected to be the kind of engineer who chases an interface question until it closes.

•  Contribute to subsea system design spanning transport, controlled lowering, seabed landing, support, connection, operation, inspection, intervention, retrieval, and decommissioning.

•  Translate mission, seabed environment, and reactor-system requirements into subsea design criteria and basis-of-design documentation.

•  Develop conceptual and preliminary designs for foundations, restraint and guide systems, lifting interfaces, wet-mate connections, umbilicals, cable routes, protective structures, and robotic-access features.

•  Define environmental and operational load cases: hydrostatic pressure, buoyancy and stability, currents and waves, seabed interaction and scour, seismic, lifting and transport loads, fatigue, corrosion, marine growth, and dropped objects.

•  Develop and document interfaces between the reactor module and surrounding marine infrastructure — mechanical, electrical, hydraulic, digital, operational, and maintenance.

•  Develop credible installation and retrieval concepts using heavy-lift vessels, lowering systems, guide wires, and subsea intervention equipment.

•  Work directly with our robotics and autonomy engineer to design for robotic serviceability: ROV and AUV access envelopes, docking and tooling interfaces, manipulator reach and clearances, inspection sightlines and sensor coverage, and recovery provisions. Because the plant is normally unmanned, robotic accessibility is a design requirement rather than a downstream check.

•  Prepare inputs for specialist analyses (structural, geotechnical, hydrodynamic, corrosion, installation, cable, connector) and support engagement with shipyards, marine contractors, and classification societies.

Qualifications

•  PhD in ocean, offshore, marine, naval, mechanical, structural, or civil engineering, or a closely related discipline.

•  4+ years in subsea systems, offshore structures, marine mechanical systems, offshore installation, or naval systems. Directly relevant graduate research may count toward part of this.

•  A solid foundation in at least one of: subsea systems engineering, offshore structural engineering, installation and lifting engineering, subsea connectors and intervention, marine mechanical engineering, naval architecture, or corrosion and materials — and genuine interest in working across the others.

•  Working knowledge of offshore environmental loading, fatigue, corrosion, installation constraints, and marine operations.

•  Ability to interpret drawings, models, load cases, specifications, and supplier documentation.

•  Strong technical writing and drawing-review skills.

Nice to Have

•  Advanced degree in a relevant engineering discipline.

•  Subsea production systems, offshore wind, subsea power infrastructure, subsea data centers, naval systems, or permanently submerged critical infrastructure.

•  Deep-water or long-duration subsea service, heavy-lift operations, module lowering, cable lay, ROV intervention, recovery operations, or marine warranty.

•  OrcaFlex, SACS, SESAM, MOSES, ANSYS, Abaqus, SolidWorks, Siemens NX, or equivalent; Python or MATLAB.

•  DNV, ABS, API, ASME, ISO, NORSOK, or USCG standards and classification frameworks.

•  Wet-mate connectors, subsea electrical distribution, pressure housings, cathodic protection, or subsea instrumentation.

•  Nuclear facilities, high-integrity pressure systems, or other highly regulated industries.
