Nuclear Systems Design Engineer in New York

n

• PhD in nuclear engineering or a closely related discipline.

\n

• 4+ years in nuclear design, analysis, operations, research, or systems engineering. Directly relevant graduate research may count toward part of this.

\n

• A solid foundation in at least one of: reactor thermal-hydraulics, reactor physics or core design, nuclear safety analysis, fuel performance, plant dynamics and controls, or nuclear systems engineering - and genuine interest in working across the others.

\n

• Experience building and documenting engineering calculations or models, including assumptions, methods, and limitations.

\n

• Ability to distinguish preliminary engineering judgment from validated analysis and licensing-quality evidence.

\n

• Strong technical writing and review skills., * Advanced degree in nuclear engineering or a related field.

\n

• Boiling-water reactors, natural-circulation systems, SMRs, advanced reactors, or marine nuclear systems.

\n

• TRACE, RELAP5, PARCS, MELCOR, SCALE, MCNP, Serpent, OpenMC, FRAPCON, SNAP, or equivalent; Python or MATLAB.

\n

• Familiarity with 10 CFR Part 50, 52, or 53 licensing, risk-informed design, PRA, or nuclear QA.

\n

• Experience developing system requirements, interface-control documents, or V&V plans.

\n

• Experience coordinating consultants, laboratories, universities, or major equipment suppliers.

You will develop reactor and nuclear-island systems and analyses, working across disciplines rather than inside a single one. We are looking for someone with a solid foundation in one nuclear-engineering area and the appetite to work across reactor physics, thermal-hydraulics, safety, fuel, mechanical systems, controls, and licensing interfaces.

\n

\n

• Contribute to development and evaluation of reactor-system configurations: core, reactor pressure vessel, primary systems, containment, decay-heat removal, emergency cooling, I&C, and supporting nuclear-island systems.

\n

• Help translate mission requirements, subsea deployment constraints, and regulatory strategy into engineering requirements and design criteria, and document the basis for decisions.

\n

• Perform first-principles calculations, reduced-order models, and trade studies; build plant models using system-analysis and reactor-physics tools.

\n

• Support definition of operating states, initiating events, accident scenarios, safety functions, and acceptance criteria.

\n

• Prepare technical inputs for consultants, laboratories, and suppliers, and support review of their deliverables.

\n

• Support design-maturity gates, NRC pre-application activities, licensing-basis development, and safety-case documentation.

\n

• Develop and document nuclear-system interfaces with subsea structures, installation and retrieval, electrical export, and remote operations.

\n

\n, Base salary, meaningful equity, and full benefits, including 401(k), medical/dental/vision, paid time off, company holidays, and parental leave, subject to company plans and policies. Compensation reflects role scope, relevant experience, technical depth, and expected impact.

\n

Compensation Range: $100,000 - $120,000 base salary, plus stock options, commensurate with experience.
