Join us and make YOUR mark on the World!

Come join Lawrence Livermore National Laboratory (LLNL) where we apply science and technology to make the world a safer place; now one of 2020 Best Places to Work by Glassdoor!

We have an opening for an experienced 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 diverse team responsible for ensuring the sustainment of NIF’s mission-critical capability of finishing crystal optics using precision diamond turning 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.

Essential Duties
- Design and characterize precision machine tool subsystems, test prototypes and 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 broadly defined established techniques and methods.
- Perform literature reviews of relevant techniques and methods within diamond turning and precision machining.
- Develop and execute hands-on engineering R&D test plans, analyze experimental results, and author and present reports under limited direction.
- Generate detailed moderately complex to complex designs of subsystems in support of optics processing equipment, including precision cleaning, coating, transport & handling, and metrology systems.
- Develop and execute 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.
- Work in collaboration with project teams consisting of engineers, designers, technicians, scientists, and coordinators, independently, under limited direction.Perform other duties as assigned.

In Addition, at the SES.3 Level
- Propose and oversee relevant hands-on laboratory R&D experiments in support of sustaining and furthering crystal finishing capabilities while providing technical leadership and project management to a diverse team of engineers, scientists, designers, and technicians in support of repairs and upgrades to equipment.
- Develop and implement new analytical solutions to a diverse range of moderate to complex problems that require modeling, statistical analysis, and creative application of established techniques and methods.
- Lead formal and informal design reviews; exercise independent judgment in determining methods, techniques, and evaluation criteria.

- Bachelor's degree in Mechanical Engineering, Controls Engineering, Precision Engineering, Manufacturing Engineering, or related discipline or the equivalent combination of education and previous relevant experience.
- Comprehensive knowledge and proficiency with precision machine structural design, assembly, real-time error compensation systems, or control design processes.
- Broad experience and comprehensive knowledge and application of moderately complex to complex engineering analysis using structural, fluid, or thermal computer codes.
- Comprehensive knowledge and proficiency with material selection, manufacturing methods, or metrology for precision tooling and hardware.
- Proficiency with materials and fabrication R&D, with an emphasis in diamond turning systems.
- Comprehensive knowledge of and broad experience with moderately complex to complex engineering hardware design, fabrication, or testing processes.
- Proficient verbal and written communication skills necessary to effectively collaborate in a team environment and present and explain technical information.

In Addition, at the SES.3 Level
- Significant hands-on experience with the design, commissioning, operation, or maintenance of complex precision mechanical systems.
- Advanced knowledge and application of complex data analysis techniques, advanced statistics, and/or modeling.
- Advanced verbal and written communication skills necessary to effectively collaborate in a team environment, present and explain technical information, and provide advice to management.

Desired Qualifications
- Master’s degree in Mechanical Engineering, Precision Engineering, Manufacturing Engineering, or related field.
- Extensive experience designing and working with precision diamond turning machines for meter-class optical substrates.
- Experience with precision metrology and characterization, live error compensation and metrology frames, controls engineering, or optical engineering.

Pre-Employment Drug Test:  External applicant(s) selected for this position will be required to pass a post-offer, pre-employment drug test.  This includes testing for use of marijuana as Federal Law applies to us as a Federal Contractor.

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.  Q-level clearance requires U.S. citizenship.  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.  For additional information, please see DOE Order 472.2

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