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 multiple openings for a Postdoctoral Researcher to conduct basic and applied research in Reinforcement Learning for optimal sequential decision-making under uncertainty, on real-world problems in healthcare, cyber security, and national security applications. These positions are in the Computational Engineering Division (CED), within the Engineering Directorate.

Essential Duties
- Conduct research in reinforcement learning to enable development of new state-of-the-art algorithms for Laboratory problem domains.
- Design, implement, and analyze techniques in reinforcement learning.
- Explore techniques for controlling simulations using approaches such as deep reinforcement learning, bandit optimization, evolutionary algorithms, model-based methods, and stochastic control.
- 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 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 PhD in Computer Science, Computational Engineering, Applied Statistics, Applied Mathematics, Operation Research, or related field.
- Knowledge and experience in reinforcement learning, active learning, or stochastic control algorithms.
- Proficiency in one or more of the following machine learning areas: deep learning, unsupervised feature learning, multimodal learning, and probabilistic graphical models.
- Experience in the broad application of two or more higher-level programming languages such as Python, Java, Matlab, R or C/C++.
- Experience with one or more deep learning libraries such as TensorFlow, Keras, Caffe or Theano, and experience with one or more deep reinforcement learning libraries such as rllab, keras-rl or OpenAI Gym.
- Demonstrated ability to develop independent research projects as demonstrated through publication of peer-reviewed literature.
- Demonstrated proficient verbal and written communication skills to collaborate effectively in a team environment and present and explain technical information.
- Demonstrated initiative and interpersonal skills and ability to work in a collaborative, multidisciplinary team environment.

Desired Qualifications
- Strong math background and experience with mathematical formulations of complex systems. Domain knowledge in biological sciences or cyber security.
- Experience with a variety of deep reinforcement learning algorithms including experience with variational Bayesian methods, nonparametric Bayesian methods, and multi-agent systems.
- Experience with utilizing simulation to model and analyze complex systems and experience with parallel computing and/or GPU computing.

Pre-Employment Drug Test: External applicant(s) selected for this position will be required to pass a post-offer, pre-employment drug test.
 

Security Clearance: This position requires either no security clearance, or a Department of Energy (DOE) L-level or Q-level clearance depending on the location of the assignment.

If you are selected and a security clearance is required, 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. 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.
