Senior Fuel Handling System Design Engineer

Position Overview

System One is seeking a highly motivated Senior Fuel Handling System Design Engineer to support advanced nuclear reactor projects for a leading clean energy client. This role will focus on the design of mechanical fuel handling and process systems , supporting plant system development from requirements definition through final design.

The successful candidate will act as a mechanical system design engineer , integrating and coordinating with multi-disciplinary engineering teams to deliver robust, safety-focused fuel handling solutions in a regulated nuclear environment.

Key Responsibilities

• Design nuclear fuel handling systems and sub-systems from requirements development through final design.
• Coordinate review of supporting analyses (thermal, seismic, structural, pipe stress, heat transfer, etc.) and integrate results into plant design deliverables.
• Create Finite Element Analysis (FEA) and Computational Fluid Dynamics (CFD) models to support conceptual and detailed system designs.
• Provide design direction related to thermal and fluid system requirements.
• Identify and apply appropriate design codes and standards (ASME, ANS, ASTM, IEEE, NFPA, etc.).
• Provide technical direction and guidance to engineers on applicable nuclear and non-nuclear design standards.
• Analyze and allocate regulatory criteria and standards to complex mechanical and process system designs.
• Support planning efforts and maintain schedule adherence for system design activities.
• Develop and manage drawing packages, including P&IDs, 3D models, and system interface drawings.
• Interface with mechanical, I&C, civil, and nuclear disciplines to define system design and performance criteria.
• Provide technical oversight of supplier projects and support technical review of supplier deliverables.
• Establish and maintain system requirements and engineering specification documents.
• Propose and support system qualification testing programs, including test execution, evaluation, and reporting.
• Generate complete design packages including calculations, design reports, drawings, and specifications.
• Develop and review technical documents such as System Design Descriptions, Interface Control Documents, and Engineering Design Specifications.
• Support licensing activities, including Safety Analysis Reports.
• Participate in and support system and subsystem design reviews.

Required Qualifications

• Bachelor’s degree in Mechanical Engineering or related discipline from an accredited university.
• Five (5) or more years of direct experience in mechanical system design.
• Demonstrated experience designing complex mechanical systems, structures, or equipment.
• Previous experience with nuclear reactors, nuclear fuel handling process systems, or similar high-performance system or equipment design is required .
• Experience working to quality standards such as ASME NQA-1 or ISO 9001 .
• Strong attention to detail and commitment to technical excellence.
• Ability to lead and coordinate engineering efforts with minimal direction.
• Ability to manage projects with competing objectives and complex design constraints.
• Ability to work on multiple simultaneous tasks requiring a multi-disciplinary approach.

Preferred Qualifications

• Experience in high temperature and multi-discipline integration highly desired.
• Experience with thermal, fluid, and mechanical system integration.
• Strong understanding of nuclear design codes and regulatory requirements.
• Excellent technical writing, communication, and presentation skills.
• Strong communication skills and ability to collaborate across engineering disciplines.
• The successful candidate will possess a high degree of trust and integrity , communicate openly, display respect, and demonstrate a desire to foster teamwork.
• Actual position starting level and title will be determined based on assessment of qualifications.

Physical & Work Requirements

• Ability to sit or stand for extended periods.
• Fine motor skills (grasping, gripping, keyboard use).
• Occasional bending, stooping, and lifting (up to 25 pounds).
• Prolonged repetitive work.
• Visual and audio-focused tasks.
• Standard office and engineering work environments (>8 hours/day).
• Travel requirement: 0–5%.
