AI Infrastructure and Advanced Computing Scientist; Scientist

Position: AI Infrastructure and Advanced Computing Scientist (Scientist 3/4)
** What You Will Do*
* ** This position is open for external candidates only to apply.*
* Help shape the AI and advanced-computing capabilities that enable scientific discovery and national-security missions. The Applied Computer Science Group (CAI-1) is seeking a Scientist 3/4 to provide technical leadership across emerging-computing testbeds, institutional AI infrastructure, and applied-AI projects.

In this role, you will combine hands-on technical work with cross-organizational leadership. You will evaluate new computing technologies, develop secure and scalable AI services, and help Laboratory teams turn promising AI concepts into useful, sustainable capabilities.

You will:

+ Lead the integration and evaluation of emerging computing architectures, accelerators, and software stacks for scientific simulation, data analysis, and AI.

+ Architect and mature AI services that span model serving, retrieval and agentic workflows, GPU resources, orchestration, observability, and on-premises or cloud environments.

+   Develop reproducible experiments and benchmarks to assess performance, scalability, reliability, usability, cost, and mission suitability.

+   Partner with researchers, computing operations, cybersecurity organizations, and vendors to define requirements, resolve technical risks, and move prototypes into reliable use.

+   Strengthen applied-AI delivery through technical consultation, project triage, reusable components, documentation, training, mentoring, and effective handoff to mission teams.

This position may be filled at either the Scientist 3 or Scientist 4 level, depending on the selected candidate's qualifications.

** Scientist 3 - $128,000-$215,900*
* At the Scientist 3 level, you will lead major technical efforts and multidisciplinary project teams.

** Scientist 4 - $153,600-$266,500*
* At the Scientist 4 level, you will serve as a Laboratory-level technical authority, establish strategy and architecture across organizations, and build institutional capabilities and programs.
