Job description
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.
What You Need
Minimum Job Requirements:
• Technical expertise: Advanced knowledge in one or more relevant areas, such as AI/ML systems, high-performance computing, computer architecture, distributed systems, accelerated computing, cloud-native platforms, or scientific software infrastructure.
• Systems development and integration: Demonstrated experience developing, integrating, or evaluating complex computing systems in Linux environments, including multiple layers such as compute, storage, networking, containers, orchestration, schedulers, model runtimes, data services, or monitoring.
• Experimental evaluation: Experience designing reproducible computational experiments, analyzing performance or system behavior, and using results to guide architecture or technology decisions.
• Technical leadership: Demonstrated ability to lead complex technical projects, establish scope and priorities, coordinate multidisciplinary contributors, manage risks, and deliver results; experience mentoring staff or students.
• Collaboration and communication: Ability to work effectively across research, operational, security, and program organizations and communicate technical findings, tradeoffs, and recommendations through clear writing and presentations.
Additional Job Requirements for Scientist 4
• Institutional impact: Significant technical achievements that have advanced AI, computing, research, or mission capabilities at a Laboratory-wide or comparable institutional scale.
• Technical strategy: Demonstrated experience establishing architectures, standards, roadmaps, or investment direction for complex computing capabilities.
• Cross-organizational leadership: Success leading large, multidisciplinary, high-risk efforts and serving as an authority for consequential technical decisions.
• Capability development: Demonstrated success building teams, funded programs, or strategic partnerships and advising senior organizational or government leaders.
Education/Experience
Scientist 3: A master's degree in a relevant STEM discipline from an accredited institution and six years of relevant experience, or an equivalent combination of directly applicable education and experience.
Scientist 4: A master's degree in a relevant STEM discipline from an accredited institution and twelve years of relevant experience, or an equivalent combination of directly applicable education and experience.
Desired Qualifications:
• Experience with GPUs or other accelerators, heterogeneous computing, parallel programming, performance analysis, or AI frameworks.
• Experience with Kubernetes or OpenShift, containers, HPC workload managers, DevOps practices, and hybrid cloud/HPC environments.
• Experience with large-language-model inference, AI gateways, retrieval-augmented generation, vector databases, document intelligence, agentic systems, or AI-assisted software development.
• Experience establishing shared research-computing or AI services, supporting users, and coordinating cybersecurity, authorization, data-governance, or access requirements.
• Experience developing proposals, working with technology vendors or external collaborators, and translating evaluation results into technical plans or investments.
• Ph.D. in computer science, computational science, data science, applied mathematics, engineering, or a related field.
Work Location: The work location for this position is onsite and located in Los Alamos, NM. All work locations are at the discretion of management.
