Working at NLR

NLR is located at the foothills of the Rocky Mountains in Golden, Colorado is the nation's primary laboratory for energy systems research and development.

Join the National Laboratory of the Rockies (NLR), where world-class scientists, engineers, and experts are accelerating energy innovation through breakthrough research and systems integration. From our mission to our collaborative culture, NLR stands out in the research community for its commitment to an affordable and secure energy future. Spanning foundational science to applied systems engineering and analysis, we focus on solving complex challenges to deliver advanced, secure, reliable, and cost-effective energy solutions. Our work helps strengthen U.S. industries, support job creation, and promote national economic growth.

At NLR, you'll find a mission-driven environment supported by state-of-the-art facilities, multidisciplinary research teams, and strong collaborations with industry, academia, and other national laboratories. We offer robust professional development opportunities, and a competitive benefits package designed to support your career and well-being.

Job Description

The National Laboratory of the Rockies (NLR) is seeking an accomplished full-time software engineer with experience in AI, optimization, applied mathematics, and high-performance computing within the Computational Science Center (CSC) with a focus on advancing energy innovation by supporting world class research and leadership in computational science.

In the CSC, we integrate discovery science, engineering, and mission delivery to translate breakthrough research into operational capabilities, with core strengths in high‑performance computing, AI/ML, modeling and simulation, and visualization. We steward state‑of‑the‑art supercomputing and data facilities, secure research environments (including classified spaces), and specialized testbeds that enable end‑to‑end development and red‑team evaluation. NLR collaborates across DOE program offices and with the defense and intelligence communities, other federal agencies, universities, and industry through public–private partnerships and technology transition pathways, while fostering a culture of scientific excellence, operational rigor, and responsible research.

In this position you will design, develop, and rigorously test software applications and components, utilizing best practices and cutting-edge technologies to pave the way for innovative, collaborative, and hybrid computing solutions supporting NLR’s mission critical research projects.

Candidates will work across the full research-to-implementation stack including designing and evaluating AI models, translating findings into production-ready systems, and occasionally diving into the quantitative underpinnings that make intelligent systems behave reliably in constrained, real-world settings. This isn't a role where AI and optimization live in separate silos. Candidates are expected to reason across both.

Strong software engineering fundamentals are the foundation. Beyond that, candidates should have meaningful experience with modern AI/ML such as deep learning, probabilistic modeling, large-scale inference, foundation models, and applied AI in a specific domain. Candidates understand the difference between a benchmark result and a deployed system, and know how to close that gap.

On the optimization side, candidates are expected to be comfortable with formulating and reasoning about constrained optimization problems. Candidates should possess a willingness to go deep when the work demands it.

Candidates should have a strong technical background, good work ethic, experience in leadership and mentorship, and be comfortable to quickly learn and apply new technologies, as the role will include self-starting and performing technical tasks independently. The role also requires collaboration and effective communication with peers, mentors, and team members. The successful candidate will not shy away from tackling challenges, but rather, demonstrate eagerness to engineer creative solutions. In this vein, the candidate should have a high degree of curiosity, excitement to work on a team, and ability to adapt to needs of different projects and challenges by gaining and utilizing new skills in support of research goals.
