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 to conduct basic and applied research in the continuum simulation and modeling of liquid drop-on-demand printing processes. You will work independently to both apply and extend commercial/opensource/LLNL software tools to develop physics-based simulation code in focus areas including volume-of-fluid and Arbitrary Lagrangian Eulerian (ALE) simulations of droplet printing processes. This position is in the Computational Engineering Division (CED) of the Engineering Directorate.Essential Duties
- Conduct modeling and simulation of droplet jetting processes, including droplet break-up, morphology, flight dynamics, heat transfer, and solidification.
- Employ and extend continuum (i.e., finite volume or finite element) commercial, open-source, and/or LLNL simulation codes to implement models and perform droplet simulations.
- Develop computational models and perform analyses of applications involving coupled structural, fluid, thermal, and/or chemical phenomena.
- Work with engineers and scientists to identify and solve challenging simulation and modeling problems.
- Pursue independent (but complementary) research interests and interact with a broad spectrum of scientists internal and external to the Laboratory.
- Collaborate with others in a multidisciplinary team environment to accomplish research goals.
- 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.Qualifications
- Recent Ph.D. in engineering, mathematics, computational science, or a related field.
- Experience developing or modifying simulations using continuum (finite-element/ finite-volume) approaches for flow physics problems.
- Knowledge of finite element methods or finite volume methods in both theory and application.
- Experience programming in C/C++, FORTRAN, Python or similar languages.
- Knowledge of analysis, modeling and simulation tools.
- Proficient verbal and written communication skills to collaborate effectively in a team environment and present and explain technical information.Desired Qualifications
- Experience developing continuum simulations for modeling two-phase systems using volume-of-fluid or Arbitrary Lagrangian-Eulerian (ALE) approaches.
- Experience with coupled fluid flow and heat-transfer simulation, including simulation of liquid solidification processes.
- Experience with massively parallel computing and significant experience in C and C++ programming.

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 one 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.
