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 a Postdoctoral Researcher to advance the science of high-power laser diode devices. You will develop characterization tools and methods for semiconductor and optoelectronic devices to enable breakthrough performance in device power, brightness, efficiency, or other required characteristics. You will be part of technical team that develops advanced diode laser technologies for integration into next-generation laser systems. This position is within the Laser Systems Engineering and Operations (LSEO) division within the Engineering Directorate. 
Essential Duties
- Conduct advanced research into novel approaches for enhancing laser diode technology.
- Design and execute hypothesis-driven experiments on diode lasers and associated optical and electronic components.
- Design, build, and commission new diagnostics for kW-class semiconductor diode laser packages, including but not limited to optical and mechanical alignment, signal processing, and data acquisition.
- Develop novel tools for material defect characterization and execute experiments to determine the role of defects in diode laser performance.
- Analyze and interpret optical, electrical, and thermal performance data, including the development and use of models when necessary, to draw conclusions and plan experiments.
- Pursue independent (but complementary) research interests and interact with a broad spectrum of scientists internally and externally to the Laboratory.
- Publish research results in peer-reviewed scientific or technical journals, and present results at external conferences, seminars, and/or technical meetings.
- Perform other duties as assigned.
- PhD degree in physics, electrical engineering, materials science, or a related field.
- Significant experience in the design and operation of optical and optoelectronic instrumentation.
- Ability to write and operate software (e.g., Python, MATLAB, LabView) for hardware control, data collection, and data analysis of experimental systems.
- Strong fundamental knowledge of solid-state physics and the principles underlying light-emitting semiconductors
- Ability to perform as an innovative experimentalist with a broad range of experience in experimental design, techniques, and execution, including developing innovative solutions to scientific and technical problems.
- Experience developing independent research projects, including publication of peer-reviewed literature.
- Proficient verbal and written communication and interpersonal skills to collaborate effectively in a multidisciplinary team environment and present and explain technical information.
- Effective initiative and interpersonal skills and ability to work in a collaborative, multidisciplinary team environment.
Desired Qualifications
- Significant working experience with and theoretical understanding of high-power semiconductor laser diode devices.

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 one year Postdoctoral appointment with the possibility of extension to a maximum of three years.  Eligible candidates are those who have been awarded a PhD at time of hire date.
