About The Position

Great minds meet great challenges. Ready to build what’s next? At PNNL, Data Scientists work at the intersection of scientific discovery and advanced machine learning, contributing across our major science and technology directorates. Each directorate addresses distinct mission-driven challenges, providing opportunities to develop novel algorithms, advance computational methods, and apply data-centric approaches to complex real-world scientific and national challenges. We’re looking for passionate Data Scientists who are driven by curiosity, rigor, and impact - individuals who excel in collaborative, interdisciplinary environments and are motivated to push the boundaries of what data and machine learning can achieve. Whether developing scalable models, designing new learning paradigms, deploying AI systems in operational settings, or translating data into actionable scientific insight, you will play a key role in advancing research and enabling high-impact decisions across domains. We’re hosting a virtual hiring event, giving you the opportunity to connect directly with our hiring teams and explore how your skills align with our work. Event Details: Our virtual hiring event will take place during the week of April 27, 2026. All applications are reviewed based on job-related skills, qualifications, and experience. Selected candidates may be invited to participate in virtual technical interviews during this timeframe and will be contacted directly with scheduling details. Apply your skills to meaningful work across our mission driven focus areas: National Security Directorate (NSD) Build resilient, secure software and data systems that support high-consequence missions—where performance, reliability, and security are critical. Physical and Computational Sciences Directorate (PCSD) Engineer platforms that accelerate scientific computing and discovery—connecting large-scale computing with data-rich scientific workflows (aligned with DOE’s integrated AI platform vision). There is a strong preference for on‑site/hybrid presence at one of our PNNL campuses, including Richland, WA or Seattle, WA based on the position.
