Distinguished Engineer, Reactor Systems (Nuclear)

Location: Remote in the United States or onsite at an existing hirify.global U.S. location. Remote travel is expected at approximately 20%; onsite travel may be approximately 10%. The role may involve work at manufacturing, assembly, testing, supplier, fabrication, construction, and installation sites.

Company

hirify.global develops fluoride-salt-cooled, high-temperature nuclear reactor technology to support the transition to clean energy.

What you will do

• Set the long-term technical vision, reactor system architecture, engineering strategy, and design philosophy.
• Provide technical authority across reactor system design, integration, analysis, testing, qualification, and deployment.
• Lead resolution of complex issues involving reactor vessels, internals, auxiliary systems, nuclear design, thermal hydraulics, safety analysis, instrumentation and controls, manufacturing, licensing, and operations.
• Guide system requirements, design bases, interface definitions, verification plans, technical documentation, and design integration reviews.
• Evaluate technical tradeoffs involving safety, manufacturing, operability, licensing, economics, and commercialization.
• Mentor engineers and represent Reactor Systems in technical reviews, audits, readiness reviews, and executive-level briefings.

Requirements

• Bachelor’s or advanced degree in Mechanical Engineering, Nuclear Engineering, or a related technical discipline.
• 20+ years of progressively increasing technical leadership experience in nuclear reactor design, reactor systems engineering, advanced technology development, complex mechanical systems, high-temperature systems, or similarly regulated engineering environments.
• Experience leading major technical scopes across complex engineering programs, preferably in nuclear, energy, chemical, oil and gas, or power generation systems.
• Experience with configuration management, design control, or product lifecycle management under ASME NQA-1, ISO 9001, or an equivalent quality program.
• Knowledge of ASME, ANSI, ASTM, ASME Boiler and Pressure Vessel Code, and related engineering standards; experience with FEA, CFD, thermal-fluid, structural, and system-level analysis.
• Work authorization may be subject to U.S. Department of Energy 10 CFR Part 810 export-control requirements.

Nice to have

• Recognized technical authority with contributions through publications, patents, standards development, invited presentations, or equivalent achievements.
• Experience with advanced reactor technology, molten salt systems, high-temperature design, reactor internals, and safety-significant mechanical components.
• Familiarity with 3D CAD tools such as SolidWorks or AVEVA.

Culture & Benefits

• Full-time employment with competitive compensation packages.
• Medical, dental, and vision benefits for employees and dependents.
• Paid vacation.
• 401(k), pre-tax health insurance, dependent care, and commuter benefits through an FSA.
• Work in office, manufacturing, testing, and construction environments as required, with occasional schedule flexibility and extended hours for critical milestones.
