Job summary

Momentum Power in New York, NY is seeking a nuclear engineer to develop reactor and nuclear-island systems, working across disciplines rather than in a single area. You will contribute to reactor-system configurations and document the basis for engineering decisions.

The ideal candidate has a PhD in nuclear engineering and 4+ years of design or analysis experience, with strong technical writing and the ability to build and document calculations.

Qualifications

• PhD in nuclear engineering or closely related discipline.
• 4+ years in nuclear design, analysis, operations, research, or systems engineering.
• Foundation in at least one area (reactor TH, reactor physics/core design, nuclear safety, fuel, plant dynamics/controls, or nuclear systems engineering).
• Experience building and documenting engineering calculations or models with explicit assumptions.
• Ability to distinguish preliminary engineering judgment from licensing-quality evidence.
• Strong technical writing and review skills.

Responsibilities

• Develop reactor-system configurations: core, pressure vessel, containment, and related subsystems.
• Translate mission requirements into engineering criteria and document decision basis.
• Perform first-principles calculations, reduced-order models, and trade studies.
• Support operating states, accident scenarios, safety functions, and acceptance criteria.
• Prepare inputs for consultants, laboratories, and suppliers; review deliverables.
• Support design-maturity gates, licensing interfaces, and safety-case documentation.
• Develop and document nuclear-system interfaces with subsea structures and remote operations.
