Nuclear Engineer Jobs in Pennsylvania: Frequently Asked Questions
How do you become a nuclear engineer in Pennsylvania?
To work as a nuclear engineer in Pennsylvania, you need at least a bachelor's degree in nuclear engineering or a closely related field from an accredited program. Pennsylvania does not require a discipline-specific nuclear license beyond the standard Professional Engineer credential, which is issued by the Pennsylvania State Registration Board for Professional Engineers, Land Surveyors and Geologists. Most employers in power generation and defense also require passing the Fundamentals of Engineering exam as a first step toward licensure.
How much do nuclear engineers make in Pennsylvania?
Nuclear engineers in Pennsylvania earn a median of about $133,250 a year, based on May 2025 Bureau of Labor Statistics wage data, ranging from around $83,250 for the lowest 10% to over $167,110 for the top 10%. Pay rises with experience, specialty, and employer.
Which companies hire nuclear engineers in Pennsylvania?
Employers hiring nuclear engineers in Pennsylvania right now include Sargent & Lundy, Hatch, and Naval Nuclear Laboratory, based on current listings on Migrate Mate as of August 2026. Pennsylvania's concentration of operating commercial reactors and defense contractors means hiring tends to be consistent, with large facilities in the Philadelphia suburbs, western Pennsylvania, and the Susquehanna Valley driving steady demand.
Which Pennsylvania cities have the most nuclear engineer jobs?
Pittsburgh, Reading, and Cranberry Township have the most nuclear engineer openings in Pennsylvania. Philadelphia and its suburbs anchor demand through Exelon's regional operations and a dense cluster of defense contractors, while Pittsburgh draws candidates toward Westinghouse Electric Company's global headquarters and the Naval Nuclear Laboratory's southwest Pennsylvania presence, making both metros reliable destinations regardless of seniority level.
Are there remote nuclear engineer jobs in Pennsylvania?
Yes, but they're rare. Nuclear engineering is predominantly hands-on work tied to reactors, test facilities, and regulated plant environments that require physical presence. About 100% of nuclear engineer openings tied to Pennsylvania are remote or hybrid as of August 2026, and those positions are mostly limited to modeling, simulation, licensing analysis, and regulatory documentation roles that don't require direct access to plant systems.
How can I get hired as a nuclear engineer in Pennsylvania with little or no experience?
The most realistic entry path is applying directly to new-graduate programs at Pennsylvania's major nuclear employers. Westinghouse Electric Company and Exelon both run structured early-career rotational and graduate development programs that place candidates without experience into supervised engineering roles. The Naval Nuclear Laboratory in Pittsburgh also recruits recent graduates through a formal new-professional program. Passing the Fundamentals of Engineering exam before graduation and completing a relevant internship at a Pennsylvania nuclear facility strengthens any entry-level application considerably.
Where can I find and apply to nuclear engineer jobs in Pennsylvania?
You can find and apply to nuclear engineer jobs in Pennsylvania on Migrate Mate, which lists current Pennsylvania openings across power generation, defense, and research sectors. Find roles that fit your experience and specialization and apply directly to the employers posting them.
