STS Lead Instrument Engineer

Date: Jan 13, 2023

Location: Oak Ridge, TN, US, 37830

Company: Oak Ridge National Laboratory

Requisition Id 9704 


We are seeking a Lead Instrument Engineer. The position resides in the Instrument Systems Engineering (ISE) Group within the Second Target Station (STS) Project at Oak Ridge National Laboratory (ORNL).


As a Lead Instrument Engineer, you will be responsible for the entire engineering design of one or more neutron scattering instruments (or beamlines). Each instrument is a scientific experiment station with unique requirements and incorporates custom configurations of neutron optics & choppers, detectors & support structures, positioning devices, vacuum and/or pressure vessels, sample environments, neutron & biological shielding, and others, many of which are first-of-a-kind or one-of-a-kind. As a Lead Instrument Engineer, you will participate in the design process but will also coordinate the work of other engineers and designers to ensure the instrument’s scientific objectives are met within the cost, schedule, and scope expectations of the STS Project. You will work alongside a Lead Instrument Scientist who is responsible for the physics design of the instrument and for specifying the science requirements. You will be responsible for overseeing the procurement and fabrication of components and beamline subsystems and will also work with installation supervisors during instrument construction. A Lead Instrument Engineer will also be a Control Account Manager responsible for the budget and schedule of your instrument. A Lead Instrument Engineer typically has a strong background in machine design and/or systems engineering.


Domestic and International travel is infrequent but will be required.


Major Duties and Responsibilities

  • Serve as a Lead Engineer for new instrument developments
  • Provide direction to other engineers and designers to ensure engineering standards are met and customer expectations are satisfied
  • Develop requirements and engineering concepts from scientific specifications
  • Lead multidisciplinary activities to ensure project requirements are met
  • Perform and document engineering calculations to ensure safety and component performance
  • Lead and participate in engineering and project reviews and respond to recommendations
  • Accurately and reliably communicate technical status and performance to instrument lead engineers and/or STS management
  • Perform work efficiently to ensure project deadlines are achieved
  • Ensure safety and quality by following STS standards and procedures
  • Maintain a solid commitment to implementing and perpetuating ORNL values and ethics


Basic Qualifications:

  • A BS degree in Mechanical Engineering, Nuclear Engineering, Civil Engineering, Engineering Science with 8 or more years of experience in relevant engineering design work. A master’s degree with 5 years of relevant experience will also be considered.
  • Three or more years’ experience in leading large engineering projects
  • Demonstrated ability to quickly grasp, prioritize and analyze complex technical problems
  • Experience working within or leading multi-disciplinary technical teams
  • Experience in 3-D Computer Aided Design (CAD)
  • Excellent written and oral communication skills


Preferred Qualifications:

  • Previous experience as a lead engineer for a neutron scattering instrument development or for a large-scale project in industry
  • Motivated self-starter with the ability to work independently and to participate creatively in collaborative teams across the laboratory
  • Ability to function well in a fast-paced research environment and to set priorities to accomplish multiple tasks within deadlines
  • Working level proficiency in Creo CAD software and Windchill Project Lifecycle Management software
  • Proficiency in Finite Element Analysis
  • Familiarity with multiple manufacturing processes and their associated design considerations
  • Familiarity with the ASME Boiler and Pressure Vessel Code
  • Experience with weldment designs and AWS drawing symbology


About the Second Target Station Project:

The Second Target Station (STS) is a >$2Billion Department of Energy project to be constructed at the ORNL Spallation Neutron Source (SNS) over the next decade. The STS will provide wholly new capabilities for the study of a broad range of materials with neutron scattering and support thousands of users from the physical, materials, and applied sciences as well as industry. The science capabilities provided by the instrument suite at the STS will complement those of the two existing neutron scattering user facilities at ORNL: the First Target Station (FTS) of the SNS and the High Flux Isotope Reactor (HFIR). The STS will deliver the highest peak brightness cold neutrons in the world, which together with advances in neutron optics, instrumentation, and detectors, will ensure U.S. leadership in neutron scattering for decades to come. STS will be capable of supporting 22 individual neutron scattering instruments (beamlines), each of which transports neutrons from the source to a shielded end station that houses a user-provided sample along with a suite of detectors. Please see for more information.


This position will remain open for a minimum of 5 days after which it will close when a qualified candidate is identified and/or hired.

We accept Word (.doc, .docx), Adobe (unsecured .pdf), Rich Text Format (.rtf), and HTML (.htm, .html) up to 5MB in size. Resumes from third party vendors will not be accepted; these resumes will be deleted and the candidates submitted will not be considered for employment.
