Original job description

Description TFE, Inc. is seeking multiple levels of Nuclear Commissioning Engineers.

Founded in 1989, TFE, Inc. provides professional, technical, and administrative personnel and services in the U.S. nuclear energy complex and other commercial ventures. At TFE we know our employees are the key to our success. We value their ideas and opinions and want to help them grow in knowledge, skills, and abilities. TFE provides competitive pay, generous PTO, paid holidays, and a top-notch employee assistance program. Our benefit offerings include an excellent 401k plan, medical, dental, vision, short-term and long-term disability, life insurance, and other ancillary benefits.

Nuclear Commissioning Engineers bridge the gap between construction and full-scale operations. You will be responsible for planning, executing, and documenting the testing and commissioning of complex nuclear systems, process equipment, and safety-critical components. The ideal candidate will ensure that all systems are safely transitioned into service in strict compliance with engineering specifications, safety standards, and regulatory requirements.

Key Responsibilities

Test Planning & Execution: Develop, review, and execute detailed commissioning plans, pre-operational test procedures, and startup protocols for nuclear facility systems.
System Turnover Management: Manage the system turnover process from construction to operations, including preparing, tracking, and closing out punch-lists and final documentation packages.
Testing & Validation: Oversee and document cold and hot functional testing, Factory Acceptance Testing (FAT), and Site Acceptance Testing (SAT).
Regulatory Compliance: Ensure all commissioning activities adhere to strict nuclear safety culture guidelines, Quality Assurance programs (e.g., ASME NQA-1), and applicable federal regulations (NRC / DOE).
Issue Resolution: Identify, document, and troubleshoot system anomalies, design discrepancies, and non-conformances. Coordinate root-cause analysis and corrective actions.
Cross-Functional Collaboration: Serve as a primary interface between construction contractors, design engineering, plant operations, quality control, and regulatory reviewers.

Requirements

Required Qualifications

Education: Bachelor’s degree in Nuclear, Mechanical, Electrical, or Chemical Engineering, or a related technical discipline. Equivalent combination of education and extensive nuclear experience may be considered.
Experience: Nuclear power generation, government nuclear facilities, or heavily regulated high-hazard industrial environments. Minimum requirements by level: Junior (3-5 years), Mid-level (5-10 years), Lead (10+years) and SMEs (15+ years)
Technical Expertise: Demonstrated experience in nuclear system testing, startup operations, or component commissioning.
Blueprint Proficiency: Strong ability to read, interpret, and work from complex P&IDs, electrical one-lines, logic diagrams, and instrument loop drawings.
Safety Culture: Deep understanding of nuclear safety standards, Conduct of Operations, and work control processes.

Preferred Qualifications

Previous experience working within [DOE (Department of Energy) / NRC (Nuclear Regulatory Commission)] regulated facilities.
Familiarity with ASME NQA-1 Quality Assurance requirements.
Professional Engineer (PE) license or specific system certifications.
Ability to obtain DOE Q Clearance / Active Secret, etc.

Working Conditions & Physical Demands

Must be able to access all areas of a nuclear/industrial site, which may include climbing stairs, ladders, and walking on uneven surfaces.
May require wearing personal protective equipment (PPE), including respirators or anti-contamination clothing when necessary.
