What is a reactor engineer?

Reactor Engineers are professionals who design, operate, and maintain nuclear reactors. They are responsible for ensuring the safe and efficient functioning of reactors used for power generation, research, or medical purposes. Their work involves monitoring reactor systems, conducting safety assessments, and developing procedures to prevent accidents. Reactor Engineers also analyze reactor performance data and collaborate with other engineers and scientists to optimize reactor operations.

What are the key skills and qualifications needed to thrive as a reactor engineer, and why are they important?

To thrive as a Reactor Engineer, you need a solid background in nuclear engineering, reactor physics, and safety protocols, typically supported by a degree in nuclear engineering or a related field. Familiarity with simulation software, reactor monitoring systems, and safety certification such as Fundamentals of Engineering (FE) or Professional Engineering (PE) is often required. Strong analytical thinking, attention to detail, and effective communication skills help you solve complex technical problems and work within multidisciplinary teams. These skills ensure the safe, efficient, and regulatory-compliant operation of nuclear reactors, which is critical for both safety and energy production.

What are some common challenges faced by reactor engineers during routine operations and how are they addressed?

Reactor Engineers often encounter challenges such as maintaining reactor stability, troubleshooting instrumentation issues, and ensuring compliance with strict safety protocols. These challenges are typically managed through continuous monitoring, collaboration with multidisciplinary teams (including safety, operations, and maintenance personnel), and adherence to established procedures. Proactive communication and regular training enable Reactor Engineers to respond effectively to unexpected events and maintain optimal reactor performance.

What is the difference between Reactor Engineer vs Nuclear Engineer?

AspectReactor EngineerNuclear Engineer
CredentialsBachelor's in Nuclear Engineering or related field; often requires licensing or certificationBachelor's or higher in Nuclear Engineering; may also require licensing
Work EnvironmentDesign, operate, and maintain nuclear reactors, often in power plants or research facilitiesResearch, develop, and improve nuclear systems, including reactors and radiation safety
Industry UsagePrimarily in power generation, naval propulsion, and research reactorsResearch institutions, government agencies, and industry R&D

Reactor Engineers focus on the operation and safety of nuclear reactors, ensuring they run efficiently and safely. Nuclear Engineers have a broader scope, including research, development, and design of nuclear systems. Both roles require similar educational backgrounds and certifications, but Reactor Engineers are more hands-on with reactor operation, while Nuclear Engineers often work on innovation and system improvements.

Reactor Core Mechanical Engineer

Ocean Atomics LLC

Bethesda, MD • On-site

$110K - $240K/yr

Full-time

Posted 29 days ago

Job description

The ocean is the largest undeveloped frontier on earth - and the next chapter of abundant energy will be written at sea. We're building the infrastructure to power it.
About Ocean Atomics (OA)
Ocean Atomics is an American company designing, licensing, and assembling a standardized nuclear electric power plant and the surrounding support systems for maritime applications. We will install these plants on any vessel built to our nuclear-ready standards, and will provide end-to-end sustainment in our planned nuclear lifecycle dockyard. We will help develop the licensed operators to unlock this new capability for your energy intensive application at sea. To move fast and to lead the creation of this new market, we are leveraging the compact, proven systems enabled by water-cooled reactors.
Our mission
Scale nuclear energy. Power generations.
Our vision
A maritime commons thriving with abundant, economical, modern, and safe nuclear-powered activity - built, serviced, and staffed by re-industrialized American shipyards and people.
Role Summary
We are seeking an experienced and highly motivated Reactor Core Mechanical Engineer to help us scale nuclear energy at sea. You will design and analyze the mechanical components and internals of the reactor core, with a focus on discerning and optimizing operation in dynamic marine environments. Flow-induced vibration, ship motions, and shock loading reshape structural integrity implications across the core's service life. Your analysis is what separates a reactor designed for a fixed terrestrial foundation from one engineered to operate reliably in maritime conditions.
This is a role we're hiring at multiple levels. The work is shared across levels; scope and accountability scales with experience.
The ideal candidate is genuinely curious about how to improve upon 60+ years of nuclear reactors at sea and is uniquely competent in tackling the core mechanical engineering challenges required to design, license, and produce a reactor system that allows commercial reactors to unlock the potential of the ocean.
What You'll Do
  • Design and analyze core mechanical components and internals for structural integrity, fatigue, and wear across operating, transient, and accident conditions including those unique to the maritime domain.
  • Evaluate flow-induced vibration of fuel assemblies, control elements, and internals, and develop design features to mitigate wear and dynamic effects in marine operational load profiles.
  • Assess the effects of ship motions and dynamic/shock loading on core mechanical performance and structural margins.
  • Coordinate with thermal-hydraulics, fuels, and structural teams to integrate mechanical design with flow, thermal, and neutronic requirements.
  • Document mechanical analyses, design basis, and qualification results, and support design reviews, testing campaigns, and regulatory documentation.

At more senior levels you will additionally:
  • Lead system-level decisions on core mechanical architecture and material selection.
  • Mentor newer engineers and review their analyses.
  • Interface directly with our regulatory team on NRC-facing documentation packages.
  • Drive cross-team trade studies across thermal-hydraulics, fuels, and structural domains.
What You Bring
Required
  • Bachelor's degree in mechanical or nuclear engineering required
  • Experience in mechanical design and structural analysis of reactor core components or internals.
  • Proficiency with finite element analysis and structural/vibration tools (e.g., ANSYS, ABAQUS, or equivalent).
  • Working knowledge of flow-induced vibration, fatigue, and dynamic/shock loading analysis.
  • Strong grounding in solid mechanics, materials behavior, and structural dynamics

Preferred
  • Background in naval architecture, marine engineering, or offshore energy.1
  • Experience with PWRs, first-of-a-kind reactor designs, or small modular reactor (SMR) programs.
  • Advanced degree in mechanical or nuclear engineering.

Don't meet every bullet? We'd still like to hear from you. If you're excited by the mission and most of this resonates, apply.
Export control notice
This role involves access to information subject to U.S. export control laws, including unclassified nuclear technology governed by the U.S. Department of Energy under 10 CFR Part 810. Depending on a candidate's status, access may require DOE authorization, which Ocean Atomics may apply for. Any offer is contingent on your ability to work in compliance with these requirements. We evaluate all applicants regardless of citizenship or national origin, except where required by law.
Why this matters
Every industry on Earth needs scalable, clean energy, and the ocean is the ideal place to unlock it. Joining Ocean Atomics means building real, lasting infrastructure - the kind that powers generations. The world needs abundant energy. Let's make it happen.
Ocean Atomics LLC is an equal opportunity employer.
We are committed to a workplace free of discrimination and do not discriminate on the basis of race, color, religion, sex, sexual orientation, gender identity, national origin, age, disability, genetic information, veteran status, or any other characteristic protected by applicable law. We are committed to providing reasonable accommodations; if you need an accommodation during the application process, contact info@oceanatomics.com.
