Are you interested in joining some of the brightest talent in the world to strengthen the United States’ security? Come join Lawrence Livermore National Laboratory (LLNL) where our employees apply their expertise to create solutions for BIG ideas that make our world a better place.

We are committed to a diverse and equitable workforce with an inclusive culture that values and celebrates the diversity of our people, talents, ideas, experiences, and perspectives. This is essential to innovation and creativity for continued success of the Laboratory’s mission.

Job Description

We have an opening for an Optoelectronics Engineer for the Master Oscillator Room (MOR) in the National Ignition Facility (NIF) to be part of the team responsible for maintaining optimal performance of all MOR systems, integrating new capabilities, and troubleshooting off-normal events.  You will be researching, designing, analyzing, modeling, testing, and fielding innovative laser technologies, systems and diagnostics.  This position is in the Laser Systems Engineering and Operations (LSEO) Division, within the Engineering Directorate.

This position 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.

In this role, you will

  • Apply fundamental knowledge to operations, maintenance, and upgrades to MOR systems.  Contribute to the development and design of well-defined, limited complexity system enhancements to increase system reliability and maintainability.
  • Participate in experiments involving laser pulse characterization, energy/power/spectral measurements, RF photonics and circuits, sensors and instrumentation, and systems engineering.
  • Perform periodic maintenance activities in the MOR.  Responsibilities include performing evaluation, calibration (offline and online), troubleshooting and supporting off-normal occurrences including off-hours on-call support, data analysis & archiving, developing test reports and presenting analyses under general direction.
  • Acquire and analyze large sets of data of limited complexity using computer-based data acquisition and controls.
  • Generate, maintain, and update control software for various MOR chasses containing embedded controllers using well-defined processes and procedures.
  • Build, repair, and troubleshoot optoelectronic systems of limited complexity including fiber amplifiers, arbitrary waveform generators, phase modulators and failsafe systems.
  • Interface with immediate supervisors, project leads, scientists, engineers, and technicians in the group to complete various projects, contributing and functioning as part of the team.
  • Contribute to the research, design, and testing of unique laser technologies, systems, and diagnostics to support the evolving missions for the National Ignition Facility and Photon Sciences (NIF & PS) Directorate, working under general direction.
  • Perform other duties as assigned.

Additional job responsibilities, at the SES.2 level

  • Apply comprehensive knowledge of engineering principles in the development of moderately complex to complex MOR sub-system designs.  Activities include collaborating with stakeholders to develop requirements, informally leading and participating in design reviews, designing and building hardware prototypes, and executing instrumentation performance evaluation, installation, commissioning, and documentation.
  • Perform moderately complex to complex analysis of MOR performance at a system level and present data to a peer review team with recommendations to enhance system performance while working under limited direction.
  • Provide engineering solutions to resolve moderately complex to complex technical and programmatic issues.


  • Ability to obtain and maintain a U.S. DOE Q-level security clearance which requires U.S. citizenship.
  • Bachelor’s degree in Electrical Engineering, Optical Engineering, Physics or the equivalent combination of education and relevant experience.
  • Fundamental knowledge of and experience working with limited complexity fiber optic technologies including modulators, attenuators, detectors, single-mode and specialized fibers, and measurement techniques.
  • Experience working with and fundamental knowledge of embedded controllers, RF electronics and circuits, and opto-electronic systems that are well-defined.
  • Experience using laboratory test equipment including oscilloscopes, signal generators, optical spectrum analyzers, energy and power meters.
  • Experience collecting, analyzing, interpreting data; writing test plans, documenting test results, and generating reports of limited complexity.
  • Fundamental knowledge of analytical software such as MATLAB, IDL or Python.
  • Basic decision making and analytical skills necessary to anticipate, analyze, and provide solutions to technical problems, while adhering to well-defined practices and procedures and working under general direction.
  • Sufficient verbal and written communication skills to effectively collaborate in a team environment and present and explain technical information.

Additional qualifications at the SES.2 level
