Requisition Id 15574

Overview:

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. Our team is made up of over 7,000 dedicated and innovative individuals! Our goal is to create an environment where a variety of perspectives and backgrounds are valued, ensuring ORNL is known as a top choice for employment. These principles are essential for supporting our broader mission to drive scientific breakthroughs and translate them into solutions for energy, environmental, and security challenges facing the nation.

We invite applications for a Principal Engineer for Geospatial Computing Infrastructure. This dynamic and visionary leader will launch and build a next-generation Geospatial Data & Computing Center to support ORNL’s geospatial high-performance computing (HPC) research portfolio within the Geospatial Science and Human Security Division. ORNL is the nation’s geospatial research laboratory. Our scientists and engineers are breaking new ground in geospatial science and technologies, advancing the state-of-the-art and scaling science for global impacts. From designing advanced sensing platforms and autonomous systems, to characterizing global population risk with increasing spatiotemporal clarity, to designing GeoAI models for supercomputer-scale applications, geospatial science at ORNL is establishing new horizons for global geospatial intelligence and human security. The Geospatial Science and Human Security Division is part of the National Security Sciences Directorate, where we translate and apply the latest advancements in ORNL and US scientific leadership to support the nation’s national and energy security needs.

Over the past decade ORNL has earned a strong reputation for delivering novel geospatial capabilities grounded in HPC, and this new role offers the opportunity to transform the foundations of these capabilities into a distinct center with its own mission of delivering leading-edge geospatial compute and data services, driving innovation at the intersection of computing and geospatial science, and advancing research outcomes across sponsors, disciplines and institutional partners. The successful candidate will have the strategic mindset, technical breadth, and leadership skills to stand up a mission-driven organization, guide its evolution, manage its operations, and cultivate a world-class team. This role is both operational (managing and optimizing assets and services today) and visionary in charting the future of geospatial compute, orchestrating large-scale investments and partnerships, and positioning ORNL as the national leader in geospatial HPC, data infrastructure, and emerging computing paradigms (edge compute, neuromorphic, quantum).

In this capacity you will be responsible for the formation of a Geospatial Data Center (GDC) built initially from current assets, then grown into a clearly demarcated resource with a growing team to support the work. Your responsibilities will include helping to define the strategic direction and the business model (service delivery + research + partnerships), establishing operating practices, building the team, and engaging sponsors and users. You will be the face of the center internally and externally, aligning with ORNL and National Security Sciences leadership and programs, and ensuring that the center becomes a trusted advisor, partner, and innovation hub in the geospatial and HPC community.

Develop geospatial validation frameworks for model outputs (e.g., comparisons to reference datasets, spatial cross-validation, summary dashboards, and automated report generation).
Support documentation, metadata development, and version tracking for data products and model releases; contribute to technical summaries, figures, and reports/publications as appropriate.
Participate in code reviews, model reviews, and data readiness reviews to ensure analytical defensibility, transparency, and fitness-for-use in operational and decision-support contexts.
Collaborate with research staff to integrate new data sources, indicators, and modeling approaches into existing workflows; communicate clearly across technical and domain teams.

Basic Qualifications

Bachelor’s degree and 3+ year’s experience in Geography, GIScience, Computer Science, Data Science, Statistics, Engineering, or a related field with a strong quantitative and software development emphasis.
Demonstrated experience with geospatial analysis using Python in a production or research to production environment leveraging common geospatial libraries (e.g., geopandas, rasterio, shapely, pyproj) and/or enterprise GIS tooling (e.g., PostGIS).
Strong software engineering fundamentals: Git-based workflows, testing, code review, and writing maintainable, well-documented code.
Experience preparing and validating raster and vector datasets (data cleaning, transformation, projection/CRS management, and quality control).
Working knowledge of machine learning and statistical modeling concepts (e.g., regression, classification, clustering, model evaluation).
Ability to work effectively in a team-based, production-oriented research environment and communicate technical results to diverse stakeholders.

Preferred Qualifications

Master’s degree in a relevant discipline or equivalent applied experience in geospatial data science, MLOps, or applied machine learning.
Experience with modern MLOps tooling and practices (e.g., MLflow or equivalent experiment tracking, model registries, containerization, reproducible environments).
Experience building data pipelines and workflow orchestration (e.g., Airflow, Prefect, Dagster, Make/Snakemake) and working in Linux/HPC environments.
Experience with large, multi-resolution geospatial datasets and performance-oriented processing (tiling, chunking, parallelization; Dask/Spark a plus).
Experience using or building agentic/LLM-enabled workflows for data discovery, extraction, and normalization, with attention to provenance, reproducibility, and quality.
Familiarity with uncertainty, data limitations, and bias in population and demographic modeling and in applied geospatial decision-support contexts.
Active or eligible U.S. security clearance or ability to obtain one.

Special Requirements:

Q clearance with SCI: This position requires the ability to obtain and maintain a Secret Compartmented Information (SCI) clearance from the Department of Energy.

Would you like to have a lasting and significant impact on a key user facility in the nation’s scientific infrastructure and strengthen U.S. scientific competitiveness? The Neutron Upgrades Project Office (NUPO) at ORNL is seeking a talented and enthusiastic Project Manager to spearhead the planning and execution of the Beryllium Reflector Replacement project at the High Flux Isotope Reactor (HFIR), a premier source of neutrons for the U.S. scientific community.

HFIR provides one of the highest steady-state neutron fluxes of any research reactor in the world. The thermal and cold neutrons produced by HFIR are used for research into the fundamental properties of materials, including biological and engineered materials, enabling researchers to make scientific discoveries and address some of the biggest challenges facing society today, such as the clean energy transition. ORNL is preparing to replace HFIR’s permanent beryllium reflector, along with other key reactor core components, to sustain and enhance HFIR’s operational performance. In conjunction with redesigning the cold neutron guide network, plans are under way to extend HFIR’s cold guide hall by more than 5,500 square feet. The cold guide hall features instruments that use cold neutrons with lower energies to unlock information about complex soft matter, such as proteins and polymers, and analyze materials with magnetic properties. Extending this guide hall will allow for reconfiguring and optimizing the facility’s cold neutron instruments to significantly improve their performance, develop new capabilities, and provide space to build new instruments. This exciting project will enable the HFIR to provide the Office of Science neutron scattering, isotopes production, materials irradiation, and other scientific missions essential to our national interests well into the future.
