Job Description

We have an opening for a Precision Mechanical Engineer to support projects in the National Ignition Facility and Photon Science Directorate (NIF & PS). You will provide solutions to a wide variety of research and development precision engineering projects and involved deliverables, through hardware design and developing advanced structural, thermal, and/or fluid analytical tools. You will be part of a multidisciplinary team responsible for ensuring the sustainment of NIF’s mission-critical capability of finishing crystal optics using precision diamond turning systems, alignment systems, or damage inspection systems. This position is in the Laser Systems Engineering & Operations (LSEO) Division within the Engineering Directorate.

This position will be filled at either the SES.2 or SES.3 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

  • Work under limited direction with moderate responsibility, use comprehensive knowledge, and exercise independent judgment to determine methods and recommend improvements within established frameworks and contribute to the fulfillment of project and organizational goals.
  • Provide solutions to design and characterize precision machine tool subsystems, test prototypes, and perform diagnostics, including assessing tolerance stack-ups, formulating error budgets, and applying measured error compensation systems.
  • Modify and update existing analytical solutions to moderately complex to complex problems that require modeling, statistical analysis, and creative application of established techniques and methods.
  • Perform literature reviews of relevant techniques and methods within diamond turning, precision machining, or optical sensor technology.
  • Participate in providing solutions to the development and implementation of hands-on engineering R&D test plans, analyzing experimental results, and authoring and presenting reports while working under limited direction.
  • Generate moderately complex to complex detailed designs of subsystems in support of optics processing equipment, including precision cleaning, coating, transport and handling, and metrology systems.
  • Contribute to the development and execution, and provide engineering support, for assembly, installation, commissioning, maintenance, and calibration procedures for subsystems.
  • Participate in precision machine assembly laboratory activities including component assembly, spare inventory, and metrology tool calibrations.
  • Contribute to the development of optomechanical measurement and alignment systems with scientific camera technology.
  • Collaborate with project teams consisting of engineers, designers, technicians, scientists, and coordinators, while working independently within established frameworks.
  • Perform other duties as assigned.

Additional job responsibilities, at the SES.3 level 

  • Function independently with minimal direction, taking significant responsibility and using advanced knowledge and judgment to establish objectives, prioritize parallel tasks, allocate resources, and collaborate in the development of innovative methods/technology to guide the completion of projects and contribute to the development of organizational goals.
  • Propose, implement, and guide relevant hands-on laboratory R&D experiments in support of sustaining and furthering crystal finishing or alignment systems capabilities while providing technical leadership and project management to a
