Required

Master's degree in Computer Science, Data Science, Applied Mathematics, or a related field

Strong Python development skills and familiarity with git, CLI tooling, VS Code

Proficiency with PyTorch and/or TensorFlow, along with other Python ML development packages; experience building, training, evaluating ML/DL models

Demonstrated ability to design statistical analyses and experiments (e.g., hypothesis tests, confidence intervals)

Experience implementing reproducible data/model pipelines and documenting assumptions, parameters, metrics, and results

Q Clearance: This position requires the ability to obtain and maintain a clearance from the Department of Energy. As such, this position is a Workplace Substance Abuse (WSAP) testing designated position. WSAP positions require passing a pre-placement drug test and participation in an ongoing random drug testing program

For employment at Oak Ridge National Laboratory (ORNL), a Real ID compliant form of identification will be required. Additionally, ORNL is subject to Department of Energy (DOE) access restrictions. All employees must also be able to obtain and maintain a federal Personal Identity Verification (PIV) card as mandated by Homeland Security Presidential Directive 12 (HSPD-12) and Department of Energy (DOE) Order 473.1A, which requires a favorable post-employment background investigation

To obtain this credential, new employees must successfully complete and pass a Federal Tier 1 background check investigation. This investigation includes a declaration of illegal drug activities, including use, supply, possession, or manufacture within the last year. This includes marijuana and cannabis derivatives, which are still considered illegal under federal law, regardless of state laws

If you have not resided in the U.S. for three consecutive years, you are not eligible for the PIV credential and instead will need to obtain a favorable Local Site Specific Only (LSSO) risk determination to maintain employment. Once you meet the three-year residency requirement, you will be required to obtain a PIV credential to maintain employment

Preferred

Experience with predictive modeling and generative AI/LLMs, including RAG systems

Familiarity with LLM inference servers (e.g., vLLM, Ollama)

Hands-on benchmarking/Test & Evaluation of AI systems

Data visualization and dashboarding (e.g., Streamlit)

Excellent written and oral communication skills

Motivated self-starter with the ability to work independently and to participate creatively in collaborative teams across the laboratory

Ability to function well in a fast-paced research environment, set priorities to accomplish multiple tasks within deadlines, and adapt to ever changing needs
