Apprentice Nuclear Engineering Technology information

What is an Apprentice Nuclear Engineering Technologist?

An Apprentice Nuclear Engineering Technologist is an entry-level professional who assists in the operation, maintenance, and troubleshooting of nuclear power plant systems and equipment. They work under the supervision of experienced technologists and engineers to learn about reactor operations, safety protocols, and regulatory compliance. Apprentices receive both classroom instruction and hands-on training to prepare for more advanced roles in the nuclear energy industry. This position is often a pathway to becoming a fully qualified Nuclear Engineering Technologist.

What are the key skills and qualifications needed to thrive as an Apprentice Nuclear Engineering Technologist, and why are they important?

To thrive as an Apprentice Nuclear Engineering Technologist, you need a solid understanding of physics, mathematics, and engineering principles, often backed by a relevant associate degree or vocational training. Familiarity with industry-specific tools such as radiation detection equipment, simulation software, and compliance with safety protocols is essential. Strong attention to detail, teamwork, and effective communication skills are crucial for ensuring safety and collaboration. These abilities and qualifications are vital to maintain operational integrity, adhere to strict regulatory standards, and support efficient nuclear facility operations.

What types of hands-on training and mentorship can an Apprentice Nuclear Engineering Technology expect during their apprenticeship?

As an Apprentice Nuclear Engineering Technology, you can expect to participate in structured on-the-job training alongside experienced engineers and technicians. You’ll work under the supervision of certified professionals, learning to operate, troubleshoot, and maintain nuclear plant systems and equipment. The apprenticeship typically includes both classroom instruction and practical assignments, allowing you to apply theoretical knowledge in real-world scenarios. Mentorship is a key component, as senior staff members offer guidance, feedback, and support to help you build technical skills and develop a strong safety mindset.

What is the difference between Apprentice Nuclear Engineering Technology vs Nuclear Engineering Technician?

AspectApprentice Nuclear Engineering TechnologyNuclear Engineering Technician
CredentialsTypically enrolled in or recently completed an associate degree or technical programUsually holds an associate degree in nuclear technology or related field
Work EnvironmentOn-the-job training, supervised, often in training facilities or plantsFull-time work in nuclear power plants, laboratories, or maintenance
Job RoleLearning and assisting with nuclear systems, gaining practical experiencePerforming technical tasks, monitoring systems, and supporting operations

While Apprentice Nuclear Engineering Technology focuses on training and gaining experience, Nuclear Engineering Technicians are fully qualified professionals performing technical duties in nuclear facilities. The apprenticeship prepares individuals for a career as a technician, with a focus on learning and development.

Supported by leading investors, Xcimer is uniquely positioned to deliver limitless, clean, fusion power to combat climate change. Join us in powering a better world with inertial fusion!
 
This is a full-time, onsite role based at our headquarters in Denver, CO.
 
As the Director of Nuclear Engineering, you will lead and grow Xcimer’s Nuclear Engineering discipline, ensuring the company applies rigorous nuclear engineering practices across all programs, facilities, and lifecycle phases. You will serve as a technical authority within Xcimer’s matrix engineering organization, partnering closely with Program leadership and peer Department Heads to establish standards, mentor engineers, and ensure high-quality technical execution. We are looking for a technical leader to apply their expertise in nuclear engineering, systems thinking, and organizational leadership to positively impact the future of energy!
Responsibilities
  • Build, lead, and grow the Nuclear Engineering Department, including hiring, onboarding, mentoring, and performance development of engineering staff.
  • Develop career paths and technical leadership pipelines for nuclear engineers while fostering a culture of technical rigor, collaboration, safety, and continuous improvement.
  • Establish, document, and maintain nuclear engineering standards, methods, and best practices across concept development, design, testing, and operations.
  • Define and maintain the nuclear design basis for Xcimer facilities and programs, ensuring assumptions, analyses, and requirements support performance, safety, and regulatory objectives.
  • Partner with Program Directors and Managers to ensure nuclear engineering activities are appropriately scoped, resourced, prioritized, and scheduled.
  • Identify nuclear engineering risks early and collaborate cross-functionally to develop and implement mitigation strategies.
  • Ensure disciplined execution of core nuclear engineering activities, including radiation transport and shielding analysis, activation analysis, source term definition, uncertainty analysis, and support for radiological safety and hazards analysis.
  • Collaborate closely with Systems Engineering, Facilities, Test, Operations, ES&H, and peer engineering departments to integrate nuclear engineering considerations into system architectures, facility designs, and operational procedures.
  • Define and execute a long-term roadmap for nuclear engineering capability growth, including external partnerships with national laboratories, academic institutions, and industry collaborators.
  • Represent Xcimer in technical forums and within the broader nuclear engineering community to build technical credibility and attract top-tier talent.
Qualifications
  • Education: Advanced degree in Nuclear Engineering or closely related technical field; PhD strongly preferred.
  • Experience: 15+ years of experience in nuclear engineering, including senior technical leadership responsibilities.
  • Demonstrated experience building, mentoring, and leading high-performing technical teams.
  • Strong foundation in radiation physics, nuclear engineering fundamentals, and analytical methods.
  • Experience with deterministic and Monte Carlo neutron/photon transport methods.
  • Experience using nuclear engineering analysis tools such as MCNP, OpenMC, or equivalent software.
  • Experience planning and managing technical work, including schedules, budgets, and performance metrics.
  • Experience operating effectively within matrix organizations and multidisciplinary technical environments.
  • Excellent written and verbal communication skills with the ability to communicate complex technical concepts to both technical and non-technical audiences.
  • Must be a U.S. citizen or national, U.S. permanent resident (current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum.
 
Desired
  • Experience within fusion energy, high-radiation facilities, or other advanced energy systems.
