About AMPERA

AMPERA is redefining clean, energy with compact, ultra-safe nuclear systems that power AI, industry, and defense with zero emissions and unmatched reliability . Our modular micro-reactors combine the best of fusion and fission to deliver scalable, deployable, and inherently safe energy anywhere.

As a fast-growing company, AMPERA blends the agility of a startup with the ambition of a global energy innovator. Joining us means becoming part of a bold mission to revolutionize how the world generates power through advanced nuclear design, safety innovation, and next-generation manufacturing.

Position Overview

We are seeking highly skilled and motivated Senior Nuclear Engineers to join AMPERAs advanced reactor development team. These engineers will play a critical role in the design, analysis, and validation of AMPERAs compact micro-reactor systems working at the intersection of nuclear physics, thermal-hydraulics, fuel systems, and materials science .

This position offers an opportunity to work on first-of-a-kind technology that combines fusion-fission hybrid principles , advanced materials, and additive manufacturing to deliver the worlds safest, most efficient nuclear energy systems.

Key Responsibilities

• Lead reactor system design and performance analysis using modern computational tools (e.g., MCNP, SCALE, RELAP5, OpenMC, or equivalent).
• Develop, model, and validate neutron transport, heat transfer, and thermal-fluid interactions for micro-reactor cores.
• Collaborate with cross-functional teams on the integration of fuel systems, control systems, and structural design.
• Evaluate reactor safety through probabilistic risk assessment and transient simulation.
• Support regulatory and licensing documentation for compliance with NRC, DOE, or DoD standards.
• Provide technical leadership and mentorship to junior engineers within the nuclear design group.
• Contribute to experimental testing programs and prototype validation.

Qualifications

• M.S. or Ph.D. in Nuclear Engineering, Mechanical Engineering, or related field.
• 7+ years of experience in nuclear systems design, reactor analysis, or related R&D.
• Expertise in neutronics, reactor physics, and / or thermal-hydraulics modeling .
• Familiarity with safety codes and design standards (ASME, NRC, DOE, ANSI / ANS).
• Experience with small modular reactors (SMRs), micro-reactors, or advanced reactor concepts preferred.
• Strong problem-solving, leadership, and communication skills.
• U.S. citizenship or eligibility for security clearance may be required due to project sensitivity.

What We Offer

• Competitive compensation.
• Comprehensive benefits including healthcare, vision, dental, and 401(k).
• Opportunity to help design and deploy breakthrough nuclear systems that power the AI and defense industries.
• Collaborative, mission-driven work environment that fosters innovation and technical excellence.
• Career growth potential as AMPERA scales to global clean energy impact.
