Job Description

We have multiple openings for Nuclear Systems Reliability Engineers to apply advanced technical knowledge in support of ongoing projects in the Superblock, a DOE Hazard Category 2 nuclear facility. You will often be involved in supporting significant R&D projects, utilizing your knowledge and experience to assist in creating innovative solutions. You will additionally apply mechanical engineering skills and judgement to maintain moderate to complex mechanical systems and programmatic equipment. These positions are in Defense Technologies Engineering Division (DTED), within the Engineering Directorate.

These positions will be filled at either level based on knowledge and related experience as assessed by the hiring team. Additional job responsibilities (outlined below) will be assigned if hired at the higher level.

These positions require full-time on-site presence due to the nature of the work.

You will 

  • Collaborate with team members to support and contribute to the analysis and testing of programmatic and nuclear facility equipment, including equipment vibration assessment, thermography, equipment operational data trending, deriving post-maintenance testing plans, writing testing procedures, and performing safety calculations.
  • Provide support and contribute to significant R&D projects, while also applying comprehensive engineering knowledge and experience to assist in creating mechanical solutions that are safe and compliant with DOE orders and specifications.
  • Work in conjunction with team members to provide engineering technical support for the troubleshooting, repair, modification, and operation of mechanical systems and programmatic equipment.
  • Contribute to and participate in the development of a predictive reliability program with the goal of ensuring operational readiness and minimizing downtime for critical systems, which include scientific tools & diagnostics, containment ventilation, cryogenic liquids, compressed gases, gloveboxes, and fire suppression systems.
  • Perform independent technical tasks and apply comprehensive engineering experience, knowledge, and judgment to successfully resolve a diverse range of moderately complex mechanical system problems and issues.
  • Assist in the development and implementation of a comprehensive preventative maintenance plan that encompasses all facility and programmatic equipment within the Superblock.
  • Participate in the implementation of a reliability-centered maintenance approach to maintenance activities to determine the optimal maintenance activity for each system and contribute to recommendations on system health and improvement through predictive maintenance.
  • Prepare detailed condition assessment reports for engineering and facility management on overall system health and develop performance metrics for moderately complex condition-based and/or predictive maintenance.
  • Perform Reliability, Availability, Maintainability, and Inspectability (RAMI) analysis, which is an engineering framework to assess and improve the overall performance and effectiveness of complex systems throughout their design and operational phases.
  • Communicate and interface frequently with assigned engineers to ensure compliance with programmatic requirements.
  • Select methods, techniques, and evaluation criteria to obtain results based on analysis of multiple, largely identifiable factors.Perform other duties as assigned.
