Company Description

Join us and make YOUR mark on the World!

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 a Senior Engineer with a background in Electrical Engineering or Applied Physics.  This position offers an exciting opportunity to combine new technology to support big physics experiments.  You will be responsible for the design, development, testing, fielding, and ongoing management of new and existing Target Diagnostic Systems within the Target Area Science and Engineering (TASE) Detector Group, supporting the National Ignition Facility and Photon Science Directorate (NIF&PS).  Technology areas include x-ray streak cameras, high-speed microchannel plate gated imagers, x-ray radiation detection, optical, and nuclear partial detection for imaging and spectroscopy, pulse dilation technology, Active Pixel Sensors (APS aka CMOS image sensor), CCD optical sensors, and radiation effects on electrical components and systems.  This position will include scope for new diagnostic development, upgrades to fielded systems, system integration, technical project management, and systems engineering duties.  You may be required to travel domestically, up to 10%-time, to partner facilities. 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,

  • Design, test, and analyze next generation, highly complex, diagnostics and detectors in support of the National Ignition Facility missions.
  • Develop detector hardware for highly complex state-of-the-art HED experiments.
  • Provide solutions to highly complex problems that require in-depth analysis and use of methods that frequently are not well defined and may be intangible.
  • Analyze and model/simulate the performance of highly complex detector system components under dynamic loads and/or challenging background noise conditions.
  • Provide technical leadership for teams of scientists and engineers working on a variety of x-ray diagnostic and detector R&D efforts; use independent judgement to devise solution methods and techniques, and evaluation criteria under consultative direction.
  • Set broad research and project vision; align Engineering’s detector capabilities with issues of critical importance to the Laboratory’s mission.
  • Present and disseminate research results at scientific conferences and in peer-reviewed publications, in open and classified environments, internal and external to LLNL.
  • Adhere to the highest standards of personnel and facility safety while leading the execution of high-energy, multi-hazard system demonstrations and experiments. 
  • Perform other duties as assigned.

Additional job responsibilities, at the SES.5 level

  • Develop innovative and creative solutions to highly complex, sensitive, unusual, and challenging problems, whose solutions represent breakthroughs in diagnostics involving methods that typically are not well defined; using extensive expertise leading efforts to advance  state-of-the-art technologies.
  • Provide extensive scientific and technical direction for projects and champion strategic technical decisions made by senior management and external customers.
  • Serve as a mentor and expert across the organization in the areas of detectors and diagnostics and serve as a representative to laboratory senior management as well as external sponsors and stakeholders with the ability to influence and advise. 


  • Ability to obtain and maintain a U.S. DOE Q-level security clearance which requires U.S. citizenship.
  • Master’s degree in electrical engineering, physics, or a related field, or the equivalent combination of education and relevant previous experience.
  • Subject matter expert-level knowledge of highly advanced concepts related to x-ray streak cameras, pulse dilation technology, high-speed microchannel plate gated imagers, x-ray radiation detection and related design principles.
  • Subject matter expertise in design, test, and analysis of pulsed power and/or electromagnetic devices and components.
  • Substantial experience and track record of success in a leadership role directing technical teams on highly complex and challenging problems in pulsed power or applied electromagnetics.
  • Highly advanced problem-solving and decision-making skills to anticipate, identify, and independently recommend appropriate actions and solutions to highly complex engineering problems that may require in-depth analysis of intangible factors.
  • Expert communication, facilitation, and collaboration skills; Ability to present and explain highly complex technical phenomena to senior management and/or external sponsors.
  • Ability to effectively manage multiple parallel tasks, often requiring the resolution of conflicting work requirements and prioritization of tasks toward predetermined long‐range targets.

Additional qualifications at the SES.5 level

  • PhD in electrical engineering, physics, or a related field; or the equivalent combination of education and relevant previous experience.
  • Nationally recognized expert in X-ray Diagnostic technology and applications in HED facilities.
  • Extensive experience and ability in a specific area of science related to X-ray Diagnostic hardware design, analysis, or simulation, involving factors that may not be well defined and require creative innovation.
