Computer Vision for High Energy Laser Alignment Systems - Postdoctoral Researcher

LLNL•Livermore, CA

14d•Hybrid

About The Position

We have an opening for a highly qualified and motivated Postdoctoral Researcher to join the National Ignition Facility (NIF) Automated Alignment team. This team develops, sustains, and improves the operational software that automatically aligns NIF laser systems prior to experiments. The role is primarily focused on computer vision and image processing, with software engineering and machine learning serving as important secondary skill sets to improve robustness, performance, and maintainability. You will work closely with multidisciplinary teams of scientists and engineers working on innovative solutions that improve performance, supporting NIF Operations, maintaining and improving legacy capabilities, and analyzing and troubleshooting off-normal conditions in an operational environment. This position is in the Computational Engineering Division (CED), within the Engineering Directorate. This position offers a hybrid schedule, blending in-person and virtual presence. You will have the flexibility to work from home one or more days per week, when consistent with team and operational needs.

Requirements
