Job Description

We have an opening for a Mechanical/Precision Engineer to join our Precision Systems & Manufacturing Group. You will apply mechanical engineering and metrology principles to contribute to and/or lead projects ranging from novel research initiatives to supporting stockpile stewardship programs. These efforts will include the planning and execution of strategies for characterizing hardware, design and development of novel metrology tools and techniques, quantification of uncertainty in new and existing measurement technologies, and beyond. You will become familiar with the ongoing priorities of the programs being supported to assist in developing proposals for future technology development that aids in the success of program objectives. Projects may involve requirements that are beyond commercially available capabilities and solutions may require modifications to commercial tools or development of advanced tools, sensors, and fabrication methods. When available technology is inadequate to meet current or future program needs, forward thinking will be essential for envisioning directions for technology development.  This position is in the Materials Engineering Division (MED) within the Engineering Directorate.

This position will be filled at either level depending on your qualifications. Additional job responsibilities (outlined below) will be assigned if you are selected at the higher level.

In this role you will 

  • Assist in the development, implementation, and qualification of unique metrology and instrumentation applications.
  • Provide engineering solutions for the manufacturing and inspection processes used in the fabrication of precision components, including tooling design, procedure development, and uncertainty analysis.
  • Perform inspection operations of limited complexity and interpret specifications and mechanical drawings.
  • Perform engineering calculations to support design, fabrication, and/or metrology operations.
  • Analyze and interpret metrology data and the methods used to collect it.
  • Work independently under general direction and collaboratively as part of a team.
  • Present technical approaches, project plans, and documentation to peers and program managers.
  • Perform other duties as assigned.

Additional job responsibilities, at the SES.2 level

  • Solve moderately complex to complex technical issues related to metrology and manufacturing operations.
  • Utilize rigorous error budgets, kinematic (exact) constraint, and other precision engineering principles to qualify processes, provide quantified design enhancements as needed to meet capability requirements, and oversee the fabrication and implementation of these designs.
  • Develop and present research and development proposals.
  • Plan and execute on strategies to quantify the performance of new and existing manufacturing and metrology technologies while working under limited direction.


  • Ability to secure and maintain a U.S. DOE Q-level security clearance which requires U.S. citizenship.
  • Bachelor’s degree in Mechanical Engineering, Precision Engineering, or the equivalent combination of education and related experience.
  • Experience in the application of uncertainty analysis and error budgeting, with the ability to apply these to both new and existing processes/equipment.
  • Fundamental knowledge of metrology principles and technologies, as well as their related application spaces.
  • Working engineering knowledge associated with machining and inspection operations and experience interpreting specifications and technical drawings.
  • Ability to work independently and collaboratively as part of a team with effective organizational and interpersonal skills.
  • Sufficient verbal and written communication skills necessary to effectively collaborate in a team environment and present and explain technical information and provide advice to management.
  • Experience with responsibility for research, design, analysis, prototyping, and early fabrication/assembly/test.
  • Experience analyzing accuracy and resolution limits in metrology tools and manufacturing equipment.

Additional Qualifications at the SES.2 Level

  • Master’s Degree in Mechanical Engineering, Precision Engineering, or the equivalent combination of education and related experience.
  • Comprehensive knowledge of metrology principles and technologies, with demonstrated ability to apply these to both new and existing moderately complex processes/equipment.
  • Experience and comprehensive knowledge in the design and evaluation of metrology systems and processes.
  • Proficient communication, facilitation, and collaboration skills necessary to effectively present, explain, influence, and advise management and/or external sponsors.
  • Experience leading or contributing to design reviews.
