About The Position

Lawrence Livermore National Laboratory (LLNL) is seeking Data Science Engineers to join the Computational Engineering Division (CED) within the Engineering Directorate, supporting Global Security’s Energy and Homeland Security (E) program. The role involves designing, building, and deploying novel data science capabilities to enhance the reliability and adversarial resilience of critical infrastructure, specifically for cybersecurity and power systems applications. Successful candidates will write code, create analytical tools and visualizations, diagnose complex systems, and discover innovative approaches to challenging problems. These positions may offer a hybrid schedule, allowing for a blend of in-person and virtual presence, with flexibility to work from home one or more days per week. The roles will be filled at either the SES.2 or SES.3 level, depending on the candidate's knowledge and experience.
