What Employers Look For
The qualifications that appear most often in reactor engineer jobs.
- Bachelor's or master's degree in nuclear engineering or closely related field
- Proficiency with reactor physics or thermal-hydraulics codes such as MCNP, RELAP, or SCALE
- Experience with NRC licensing, safety analysis reports, or design-basis calculations
- Active or eligibility for a Department of Energy or Department of Defense security clearance
- Knowledge of nuclear fuel cycle, core design, or reactor operations principles
- Familiarity with 10 CFR regulatory requirements and nuclear quality assurance standards
Tips for Your Reactor Engineer Job Search
Tailor your resume to reactor type
Light-water reactor experience and advanced reactor design are distinct skill sets to hiring managers. Specify the reactor type, neutron spectrum, and core design tools you've worked with so screeners can immediately place your background against the opening.
Lead with your clearance status
Many reactor engineer roles at national labs and defense contractors require a security clearance. Put your clearance level and current status near the top of your resume so recruiters don't have to hunt for it and your application clears the first filter.
Apply early to roles that fit
Migrate Mate lists reactor engineer openings from across the United States in one place, so you can find roles that match and apply directly to each listing.
Highlight simulation and analysis tools
Proficiency with MCNP, RELAP, SCALE, or TRACE is often what separates candidates on paper. Name the specific codes, the analyses you ran, and the physical phenomena you modeled rather than listing software generically.
Prepare for design-basis scenario questions
Technical interviews almost always include loss-of-coolant accident scenarios or reactivity management questions. Walk through your analytical approach aloud, reference the safety criteria you applied, and explain how your conclusions fed into licensing or design decisions.
Research the facility's regulatory history
Before your interview, review the plant's or lab's recent NRC inspection reports and any corrective action trends. Referencing a specific technical challenge the site has navigated signals genuine operational awareness and sets you apart from candidates who only studied the job description.
Reactor Engineer Jobs: Frequently Asked Questions
Which companies are hiring the most reactor engineers?
The companies hiring the most reactor engineers right now include Kairos Power, Naval Nuclear Laboratory, and Lydian, with the largest share of openings in California, New York, and Massachusetts, based on current listings on Migrate Mate as of November 2026. Demand is concentrated at nuclear utilities, national laboratories, and advanced reactor developers scaling toward deployment.
How many reactor engineer jobs are remote?
About 45% of reactor engineer openings are fully remote or hybrid as of November 2026, reflecting the hands-on and security-sensitive nature of most reactor work. Roles most likely to allow remote arrangements include reactor physics modeling, fuel cycle analysis, and licensing support that does not require on-site access to plant systems or classified facilities.
How do you become a reactor engineer?
You typically start with a bachelor's degree in nuclear engineering, although mechanical, electrical, or physics degrees with relevant coursework are accepted by many employers. From there, gaining proficiency in industry-standard neutronics or thermal-hydraulics codes is essential. Many engineers enter through internships at national laboratories, nuclear utilities, or reactor vendors, where they build hands-on analysis and licensing experience before moving into full engineering roles.
How do you get hired as a reactor engineer with little experience?
Focus on demonstrating analytical competency with codes like MCNP or RELAP through coursework projects or thesis work, since employers weigh simulation ability heavily at the entry level. Internships at national laboratories or nuclear utility training programs are the most direct path. Applying for roles explicitly labeled junior, associate, or engineer-in-training improves your chances, and obtaining a Fundamentals of Engineering credential can strengthen an early application.
What does the reactor engineer interview process look like?
Most reactor engineer interview processes begin with a recruiter screen focused on clearance eligibility and core technical background. A technical phone or video interview follows, typically covering reactor physics concepts, safety analysis methodology, or a specific code you listed on your resume. Final rounds usually involve a panel with engineering leads who walk through a design-basis or accident scenario in depth, sometimes asking you to review a simplified problem on the spot before discussing your approach.
Where can I find and apply to reactor engineer jobs?
You can find and apply to reactor engineer jobs on Migrate Mate, which lists current openings from employers across the United States. Search the listings to find roles that match your experience, specialization, and location preference, then apply directly to each one that fits.
