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. This is on-site, full-time work 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 RAMI (Reliability, Availability, Maintainability, and Inspectability) analysis to assess and improve the performance of complex systems through design and operation. 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. Additional job responsibilities, at the SES.3 level Lead and/or provide technical guidance and direction in the development of project reliability plans for significant R&D projects, while applying advanced level engineering knowledge and innovation to create mechanical solutions and resolve complex problems, ensuring safety and DOE compliance. Utilize Reliability-Centered Maintenance (RCM) to identify and analyze potential equipment failures and determine appropriate maintenance strategies. Lead the development and implementation of a comprehensive, predictive maintenance plan for all equipment within the Superblock and across multiple sites. Lead the development and implementation of key performance metrics in equipment operability, maintainability, and reliability. Lead corrective actions in response to off-normal events within the scope of equipment maintenance and repair. Evaluate and influence development priorities, providing recommendations to project leadership as necessary. Qualifications Ability to secure and maintain a U.S. DOE Q-level security clearance which requires U.S. citizenship. Bachelor’s degree in engineering, engineering technology, or related technical discipline or the equivalent combination of education and related experience. Demonstrated mechanical aptitude as evidenced by past engineering or moderately complex repair projects. Comprehensive knowledge of and experience with calculations, specifications, drawings, and design criteria for mechanical systems. Experience with scientific instruments and related systems, and understanding of how these instruments function. Ability to identify, develop and communicate recommendations regarding equipment maintenance and implement them successfully. Experience working in a highly configuration managed environment. Additional qualifications at the SES.3 level Independent thinking and ability to understand advanced technical documentation for solving complex problems. Significant experience in the design or maintenance of facility-related mechanical systems such as ventilation, fire protection, liquid nitrogen/argon systems, chilled water systems, or boiler systems. Advanced leadership skills and experience directing teams in a highly regulated environment. Experience delivering multiple projects on budget and schedule. Ability to reprioritize programmatic direction as needed and communicate effectively with stakeholders. Strong verbal and written communication and negotiation skills. Qualifications We Desire Active security clearance. Experience maintaining scientific instruments (high-vacuum, high-temperature, X-ray, laser systems, calorimeters, etc.). Facility engineering and nuclear industry code compliance expertise. Qualification as a Cognizant System Engineer in a nuclear facility. Familiarity with Nuclear Materials Control & Accountability, Hazardous Waste Management, and Nuclear Facility Quality Assurance.
