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 2019 Best Places to Work by Glassdoor!

We have an opening for a postdoctoral researcher in the area of laser physics, laser materials processing and material science with emphasis on laser-matter interactions in metals and metals-based additive manufacturing. You will develop new diagnostics to study laser-matter interaction across several applications such as laser micro-machining, additive manufacturing technologies, and laser-induced shocks in materials and contribute to MSDs capabilities in laser-matter interaction science which includes the development of new laser system requirements for emerging applications. This position is in the Laser Material Interaction Science Group in the Materials Science Division. Essential Duties- Conduct fundamental research in laser-matter interaction science, laser-materials processing and related microscale characterization.- Develop laser-based approaches for studying and processing materials.- Perform complex measurements, analysis, and modification of optical systems.- Engineer, construct, and modify optical apparatus for materials characterization.- Contribute to and actively participate in the conception, design and execution of research to address defined problems.- Pursue independent but complementary research interests and interact with a broad spectrum of scientists internally and externally to the Laboratory.- Collaborate with scientists in a multidisciplinary team environment to accomplish research goals.- Document research; publish papers in peer-reviewed journals, and present results within the DOE community and at conferences.- Perform other duties as assigned.
Qualifications- Recent Ph.D. Physics, Material Science, Chemistry, Mechanical Engineering, Chemical Engineering or related field.- Experience in laser technology and optics, and in optical diagnostics including, e.g. interferometry, pump-probe spectroscopy, and high-speed imaging.- Knowledge of thermal and optical properties of materials, e.g. metal alloys, wide gap semiconductors and VisNIR optical materials.- Knowledge of shock physics and high strain rate phenomena and of high-power laser propagation and related nonlinear optical effects.- Experience with fundamentals of laser-matter interactions and with CW and pulsed (fast/ultrafast) laser systems.- Ability as an innovative experimentalist with a broad range of experience in experimental design, techniques, and execution.- Proficient interpersonal skills necessary to interact with a diverse set of scientists, engineers, and other technical and administrative staff with the ability to work independently as well as in multidisciplinary research teams.- Proficient fundamental written and verbal communication skills with demonstrated capabilities in delivering presentations and preparing written reports.Desired Qualifications- Experience in using class 4 lasers, optics layout and engineering.- Experience in computer programming for data analysis (e.g. Python, Matlab, Mathematica, C/C++), or with computer software for instrumentation design and control (e.g. LabView, Zemax).- A solid mathematical background and knowledge of optical transport theory.

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, wewill initiate a Federal background investigation to determine if youmeet 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 two year Postdoctoral appointment with the possibility of extension to a maximum of three years. Eligible candidates are recent PhDs within five years of the month of the degree award at time of hire date.
