General Atomics Electromagnetic Systems (GA-EMS) designs and manufactures first-of-a-kind electromagnetic and electric power generation systems. GA-EMS? expanding portfolio of specialized products and integrated system solutions support critical fleet, space systems and satellites, missile defense, power and energy, and process and monitoring applications for defense, industrial, and commercial customers worldwide.

We recognize and appreciate the value and contributions of individuals with diverse backgrounds and experiences and welcome all qualified individuals to apply.

We currently have an exciting position for an experienced Nuclear Engineer to support our Nuclear Technologies and Materials (NTM) division in San Diego, CA. Under general direction with limited review, this position is responsible for developing and analyzing nuclear reactor designs including develop innovative advanced core design technical and engineering solutions to meet complex requirements for the GA-EMS Fast Modular Reactor, nuclear thermal propulsion and space power applications.


  • Independently perform difficult/complex engineering and design work with instructions as to the general expected results.
  • Provide practical solutions to technical engineering problems in nuclear reactor design, manufacturing and operation to support licensing, construction, startup and commissioning phases.
  • Document findings and communicate reports and technical presentations at engineering meetings and participate in program reviews.
  • Provide support and guidance to other moderately experienced staff members working on reactor engineering including neutronics and thermal/fluids analyses, nuclear systems evaluations and core/assembly analysis.
  • Support future NTM engineering needs required to accomplish technical goals.
  • Address technical issues requiring creative approaches to resolving unusual or complex engineering problems with accuracy, completeness, and timeliness.
  • May assume technical and engineering responsibility for the success of key projects.
  • Be the focal point for technical communication with the Company management and may represent the Company as a technical contact to customers and/or government regulatory agencies.
