Experience with MLIP frameworks such as HIP-NN, MACE, NequIP, Allegro, ANI, and UMA . Experience with atomistic simulation software such as LAMMPS, ASE, GROMACS, OpenMM, TorchSim , or related MD simulation packages. Experience with MLIP-based molecular dynamics , including system preparation, simulation execution, trajectory analysis, and evaluation of model stability and accuracy. Experience with active learning , uncertainty quantification, configuration selection, automated dataset generation, or related methodologies. Experience developing and managing automated and parallel scientific workflows , including task execution systems, dependency management, and pipeline execution on distributed computing resources. Experience with HPC systems , including running and managing applications on multi-node, GPU-accelerated systems. Experience with HPC resource and workload management systems such as Slurm , using workflow methodologies and/or tools such as Parallel, Flux or Parsl . Familiarity with concepts of parallelism, scalability, and efficient utilization of computational resources. Experience with GPU accelerators and computing ecosystems such as CUDA and/or AMD ROCm/HIP. Experience with performance profiling and optimization of scientific applications, particularly molecular dynamics and machine learning applications. Familiarity with electronic structure and quantum chemistry methods , such as density functional theory (DFT), and their use in generating reference data for MLIPs. Experience with modern scientific software engineering practices, including Git, automated testing, software environments, continuous integration, documentation, and collaborative development . Familiarity with parallelization and high-performance programming techniques such as MPI, OpenMP, multiprocessing, or distributed computing in Python . Track record of publishing research results in peer-reviewed scientific journals and presenting research at scientific conferences. 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. Special Requirements: Applicants cannot have received their Ph.D. more than five years prior to the date of application and must complete all degree requirements before starting their appointment. The appointment length will be up to 24 months with the potential for extension. Initial appointments and extensions are subject to performance and availability of funding. 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. For foreign national candidates: 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. Please submit three letters of reference when applying to this position. You may upload these directly to your application or have them sent to [email protected] with the position title and number referenced in the subject line. Instructions to upload documents to your candidate profile: Login to your account via jobs.ornl.gov View Profile Under the My Documents section, select Add a Document About ORNL: As a U.S. Department of Energy (DOE) Office of Science national laboratory, ORNL has an impressive 80-year legacy of addressing the nation’s most pressing challenges.
