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 openings for Chemical Engineers who will be integral members of an interdisciplinary team responsible for conducting and supporting research on the Diode-Pumped Alkali Laser (DPAL) and other laser activities. You will lead the development and application of integrated system models to assess and quantify design trade space against system performance requirements in support of the NIF&PS Principal Directorate within the Department of Defense Technologies (DoDT) Program.  This position is inthe NIF Optics and Target Materials group of the Materials Science Division.

This position will be filled at either the SES.3 or SES.4 level depending on your qualifications. Additional job responsibilities (outlined below) will be assigned if you are selected at the higher level.

Essential Duties
- Provide advanced scientific support to the DPAL program, while collaborating with scientists, engineers, and high-level technical personnel.
- Provide process and systems engineering support, with a strong emphasis on materials chemistry and laser-matter interactions.
- Leverage systems engineering best practices to guide systems design and risk mitigation activities, including determination and documentation of technical objectives, Concept of Operations (ConOps), requirements, interfaces, and risk mitigation plans which require in-depth analysis of multiple tangible and intangible factors.
- Collaborate with scientists and engineers on DPAL system and subsystem activation, testing, and troubleshooting.
- Develop and present written analyses and verbal briefings that capture and communicate research results as well as periodic progress reports.
- Collaborate with others in a multidisciplinary team environment to accomplish program goals.
- Perform other duties as assigned.
In Addition at the SES.4 Level
- Develop and implement broader systems engineering strategy for laser projects or programs, integrating laser physics, electrical, mechanical and other efforts toward accomplishing program goals.
- Influence broad project vision, strategy and technical direction acting as a technical leader on projects/programs, while serving as a subject matter expert related to chemistry and laser-matter interactions.
- Develop new ideas and redefine requirements that impact organizational operations or directions.

- PhD in Chemical Engineering or related field, or the equivalent combination of education and related experience.
- Advanced problem-solving and decision-making skills to anticipate, identify, and provide solutions to highly unusual, complex, and/or sensitive problems that require in-depth analysis and extremely innovative approaches.
- Significant experience with system and subsystem activation, testing, and troubleshooting.
- Advanced knowledge with both analog and discrete instrumentation, data acquisition and signal processing/conditioning.
- Relevant experience with electronic measurement diagnostics including: high purity gas analyzers, custom-built gas phase detectors based on real-time deconvolution of spectral absorption, standard mass flow meters, mass flow controllers, temperature controllers, capacitance manometers, pressure controllers, IR measurement of temperature, and/or real-time spectrometers for monitoring diode performance.
- Significant experience with analysis, modeling, and simulation of flowing systems involving simultaneous heat and mass transfer.
- Advanced written and verbal communication skills necessary to deliver presentations and prepare written reports, explain technical information, and provide advice to management.
- Advanced interpersonal skills necessary to interact with a diverse set of scientists, engineers, and other technical and administrative staff.
In Addition at the SES.4 Level
- Expert knowledge of and significant experience with documentation standards including drawings, procedures, statements of work and test plans.
- Extensive experience with system level design, architecting, and project management, and/or experience as a Lead Systems Engineer/Architect for systems involving complex and multi-disciplinary elements, and significant experience preparing, leading and participating in design reviews.
- Expert communications skills with ability to influence senior management and help direct project direction.

Desired Qualifications
- Knowledge of formal methods of experimental design and analysis and experience with common simulation tools (e.g., ANSYS/CFX/FLUENT, COMSOL, Matlab/Simulink).
- Experience in the field of laser/matter interactions (e.g., laser absorption, heating, ablation) and in design and operation of pilot-scale experimental facilities, serviced by high-purity fluid (gas and liquid) support systems and < Class 100 process and assembly facilities.
- Familiarity and/or experience with basic laser and LED architectures and operating principles, near and far field measurement techniques of the laser (multi-pass), and of diagnostic beams (single pass), beam quality, wavefront measurement and correction using adaptive optics, power meters, fast power diodes.

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.

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