This position resides in the Target Engineering Group in the Neutron Technologies Division, Neutron Sciences Directorate at Oak Ridge National Laboratory (ORNL). Our group is responsible for activities supporting both new designs (e.g, Proton Power Upgrade Project, Heavy Water Recombination) and modifications to existing technical component utility systems which support neutron production and neutron beam instrument systems. This position reports to the Target Engineering Group Leader in the Target Development, Engineering and Operations Section. Major Duties/Responsibilities: * Support fabrication, commissioning, operation, troubleshooting and maintenance of the unique complex water and gas utility systems. * Maintain the process design basis documents for the system (e.g., P&IDs, PFDs, mechanical drawings, calculations, operating procedures, applicable parts of the documented hazard and accident analyses, vendor submittals) and act as the design authority for assigned systems. * Work with Operations and Maintenance staff to ensure reliable operations of all Target Systems. * Support the Reliability Program by providing system and component information to the Reliability Engineer as required (e.g. system health reports, critical spares, etc.). * Specify and procure system spare components and ensure integration into the asset management program. * Produce accurate and concise technical reports and represent SNS at conferences and/or workshops as appropriate. * Prepare presentations for and respond to recommendations from technical design reviews and advisory committees. * Evaluate system performance, identify operational trends and support corrections to off-normal operations and accurately communicate technical status and performance to ORNL management. * Act as the Technical Approver (TA) for procurement of new, replacement or upgraded system equipment. * Ensure consistency between the design basis and requirements, the system documentation and the physical configuration. * Develop and approve design changes to systems per NTD procedures. * Develop and maintain long-term plans for system maintenance and upgrades. * Enhance the technical/professional skills of others through active mentoring and training. * Comply with ORNL environment, safety, health, radiation control, and quality program requirements. * Deliver ORNL's mission by aligning behaviors, priorities, and interactions with our core values of Impact, Integrity, Teamwork, Safety, and Service. Promote equal opportunity by fostering a respectful workplace - in how we treat one another, work together, and measure success. ## Related Videos - [Model Based Systems Engineering in an Agile Product Development Process](https://www.wearedevelopers.com/videos/68-model-based-systems-engineering-in-an-agile-product-development-process) - [From Messy Queries to Scalable Systems - How Data Engineering actually works](https://www.wearedevelopers.com/videos/100203-from-messy-queries-to-scalable-systems-how-data-engineering-actually-works) - [101 brilliant things of C++](https://www.wearedevelopers.com/videos/181-101-brilliant-things-of-c) - [How I saved 200K/yr in direct costs writing 0 code lines in K8s](https://www.wearedevelopers.com/videos/1055-how-i-saved-200k-yr-in-direct-costs-writing-0-code-lines-in-k8s) - [Tackling Complexity With Functional Programming And Kotlin](https://www.wearedevelopers.com/videos/705-tackling-complexity-with-functional-programming-and-kotlin) - [Automated Driving - Why is it so hard to introduce](https://www.wearedevelopers.com/videos/628-automated-driving-why-is-it-so-hard-to-introduce) ## Related Articles - [Is Software Engineering Hard?](https://www.wearedevelopers.com/magazine/448-is-software-engineering-hard) - [Data Engineer Salary UK](https://www.wearedevelopers.com/magazine/253-data-engineer-salary-uk) - [The Ultimate Software Engineer Career Path Guide for 2023](https://www.wearedevelopers.com/magazine/146-the-ultimate-software-engineer-career-path-guide-for-2023) - [Software Engineer Career: Things You Should Know](https://www.wearedevelopers.com/magazine/143-software-engineer-career-things-you-should-know) - [What is Software Engineering?](https://www.wearedevelopers.com/magazine/289-what-is-software-engineering) - [Top Characteristics of a Software Engineer](https://www.wearedevelopers.com/magazine/166-top-characteristics-of-a-software-engineer)
