Science and Technology on a Mission!

For more than 60 years, the Lawrence Livermore National Laboratory (LLNL) has applied science and technology to make the world a safer place.

We have an opening for a Mechanical Engineer with an emphasis in Cryogenic Engineering. You will upgrade and maintain operation status of the Cryogenic Target Positioner (CryoTARPOS) for the Target and Diagnostic Delivery System (TADDS) group supporting the National Ignition Facility & Photon Science (NIF&PS) Directorate. The NIF utilizes complex cryogenic systems and plans to develop additional systems in support of future missions. You will provide technical solutions in support of operations, maintenance, and problem solving related to cryogenic systems using large capacity 4K Gifford-McMahon cryocoolers. This position is in the Laser Systems Engineering and 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.

Essential Duties
- Provide mechanical engineering solutions to resolve moderately complex technical and programmatic issues, maintenance, operations, and commissioning activities, to maintain operational status of NIF facility subsystems.
- Independently define and prepare operating procedures and maintain laboratory safety standards. Direct, follow, and adhere to written, operational, and safety procedures in the course of completing job assignments.
- Perform independent technical analysis to provide solutions for a diverse range of moderate to complex issues.
- Select methods, techniques, and evaluation criteria to obtain results based on analysis of multiple, largely identifiable factors.
- Resolve technical issues impacting the daily operation of the National Ignition Facility by providing troubleshooting guidance and implementing innovative technology designs.
- Identify upgrades to improve system efficiency and reliability, interact with designers to develop designs, and explore a variety of approaches within generally established methods and recommend improvements/processes as appropriate.
- Communicate and coordinate Cryogenic and Target Systems and Large Positioners activities with the supervisory staff in the NIF Control Room. Be knowledgeable of all routine operating procedures, assisting Cryo technician staff as required.
- Present work through formal and informal reports and presentations.
- Perform other duties as assigned.
In Addition at the SES.3 Level
- Collaborate with a team of engineers, staff, and technicians responsible for commissioning and maintaining operational status of NIF facility sub-systems, including cryogenic systems, gas supply systems, vacuum systems, and related control systems.  Special emphasis on problem resolution.
- Conduct research into new innovative designs for cryogenic positioner systems and design/conduct experiments to characterize components.
- Direct technicians to design, build, or modify specialized process equipment.

Qualifications
- Master’s (MS) degree in Mechanical Engineering or the equivalent combination of education and related experience, and a demonstrated ability to perform independent work.
- Comprehensive knowledge of and experience in mechanical and cryogenic system design, fluid mechanics and structural analysis techniques.
- Experience utilizing sound engineering principles to provide practical solutions to moderately complex problems involving thermal connectivity, temperature control, and precision movements.
- Experience providing technical insight, oversight, and direction as it relates to solving problems in the NIF facility that involve moderately complex mechanical and cryogenic systems.
- Experience operating PC and/or Macintosh computers to collect, analyze, and document scientific results from analysis and offline testing.
- Experience working effectively in a dynamic multidisciplinary environment, which includes working with scientists, engineers, technicians, and designers.
- Demonstrated proficient verbal and written communication skills necessary to communicate effectively with technical support personnel on requirements, design, safety, construction, or modification of process or pilot-scale equipment or systems, and to effectively collaborate in a team environment and present and explain technical information.
- Ability to pass NIF Radiological Worker II qualification. Ability to work in confined or restricted movement areas, Beryllium and radiologically contaminated areas, and areas where respirator use may be required.
In Addition at the SES.3 Level
- Significant experience utilizing sound engineering principles to provide practical solutions to complex problems.
- Significant experience providing technical insight, oversight, and direction as it relates to solving problems in the field that involve complex mechanical systems.
- Advanced verbal and written communication skills necessary to communicate effectively with technical support personnel on requirements, design, safety, construction, or modification of process or pilot-scale equipment or systems, and to effectively collaborate in a team environment and present and explain technical information and provide advice to management.

Desired Qualifications
- PhD in Mechanical, Electrical, or Facility Engineering.
- Experience working within a nuclear, military, or highly technical laboratory environment.

Pre-Employment Drug Test:  External applicant(s) selected for this position will be required to pass a post-offer, pre-employment drug test.
 

Security Clearance:  This position requires a Department of Energy (DOE) Q-level clearance.

If you are selected, we will initiate a Federal background investigation to determine if you meet eligibility requirements for access to classified information or matter. In addition, all L or Q cleared employees are subject to random drug testing.  If you hold multiple citizenships (U.S. and another country), you may be required to renounce your non-U.S. citizenship before a DOE L or Q clearance will be processed/granted.

 

Note:   This is a Career Indefinite position. Lab employees and external candidates may be considered for this position.
