The HPC Consulting team provides direct support to HPC customers to enhance the productivity of the user community by providing quality technical support for a wide range of workloads, including: * Large-Scale Modeling & Simulation (e.g., physics, engineering, climate) * Artificial Intelligence & Machine Learning (AI/ML) deployments * Emerging software for next-generation computing needs Team Responsibilities Our Consultants are a user-facing team who provide support and engage with LANL customers via documentation, consulting, and training. As HPC Consultants, we are a single point of contact for HPC systems and deliver customer-focused services, tools, and software. The Division's goal is to create an effective HPC environment in which scientists can be as productive as possible on world-class supercomputing systems. The HPC Division supports the Los Alamos National Laboratory (LANL) mission by managing a world-class supercomputing center. We support stockpile stewardship for NNSA/DOE and accelerate scientific discovery for scientists. We integrate and support some of the world's largest supercomputers during an exciting time in computing, with a focus on traditional large-scale simulations, data science, artificial intelligence, and machine learning. HPC Engineer 2 ($106,400-176,000) * Direct Customer Support: Provide expert guidance and consultation to scientists, engineers, and other HPC users to enhance their workflows and enable effective use of HPC systems through phone, email, ticketing systems, and in-person consultations. * Documentation and Training: Develop user guides, best practices, and training materials to help the user community get the most from the HPC environment. * System Efficiency: Work with HPC system administrators to identify issues and improve overall system performance and resource utilization. * Independent Problem Solving: Work independently to implement customer solutions to current problems and enhance the HPC user environment. * External Representation: Represent LANL HPC Consulting at workshops, meetings, and conferences with other HPC and NNSA/DOE sites. * HPC Application Support: Provide in-depth support for users of HPC systems, including installation, configuration, and troubleshooting of scientific and engineering applications. * Performance Optimization: Analyze and optimize the performance of parallel applications and workflows to ensure efficient use of HPC resources. * Code Profiling and Tuning: Collaborate with software developers and users to profile and tune applications for performance, memory usage, and scalability on HPC platforms. HPC Engineer 3 ($128,000-215,900) In addition to the duties outlined above, a successful HPC Engineer 3 candidate will be required to: * Advanced Application Support: Serve as the go-to technical resource for the most complex scientific and engineering application issues, including deep debugging of parallel codes, build failures, and cross-platform portability problems. * Performance Engineering: Conduct advanced profiling, tuning, and optimization of parallel applications across CPU and GPU architectures, identifying bottlenecks in memory, I/O, communication, and scalability. * Software Stack Expertise: Maintain deep working knowledge of compilers (NVIDIA HPC SDK, Intel, LLVM, GNU), scientific/math libraries, and environment management tools (Environment Modules, Spack, or similar) to support and troubleshoot the HPC software stack. * Parallel Programming Depth: Apply advanced knowledge of parallel programming models (MPI, OpenMP, threading, CUDA/HIP) to help users decompose problems, port applications, and resolve scaling issues. * Workflow & Container Support: Support advanced computational workflows, including containerized applications and container runtimes (Charliecloud, Singularity/Apptainer, Docker, and Podman), across HPC and hybrid environments. * Technical Representation: Represent LANL HPC Consulting at workshops, conferences, and technical meetings across the DOE Complex, sharing solutions and gathering emerging best practices. * Knowledge Transfer: Enhance the technical expertise of junior staff through informal mentoring and knowledge-sharing, focused on real problem-solving rather than formal supervision. ## Related Videos - [Python Data Visualization @ Deepnote (w/ PyViz overview)](https://www.wearedevelopers.com/videos/113-python-data-visualization-deepnote-w-pyviz-overview) - [Docker network without Docker](https://www.wearedevelopers.com/videos/1418-docker-network-without-docker) - [Shipping Faster with Less: Render on Cloud Hosting, AI Workloads, and the Future of DevOps](https://www.wearedevelopers.com/videos/1894-shipping-faster-with-less-render-on-cloud-hosting-ai-workloads-and-the-future-of-devops) - [Coffee with Developers - Stephen Jones - NVIDIA](https://www.wearedevelopers.com/videos/1303-coffee-with-developers-stephen-jones-nvidia) - [Docker exec without Docker](https://www.wearedevelopers.com/videos/1094-docker-exec-without-docker) - [Discover the open source trio you didn’t expect: .NET and PostgreSQL on Linux](https://www.wearedevelopers.com/videos/2042-discover-the-open-source-trio-you-didn-t-expect-net-and-postgresql-on-linux) ## Related Articles - [Top 6 Hackathons for Developers in 2023](https://www.wearedevelopers.com/magazine/263-top-6-hackathons-for-developers-in-2023) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [7 Cloud Computing Trends Coming in 2025 for Developers](https://www.wearedevelopers.com/magazine/412-7-cloud-computing-trends-coming-in-2025-for-developers) - [Best US AI Conferences for CTOs in 2026: Build vs. Buy, Vendor Evaluation, and Peer Intelligence](https://www.wearedevelopers.com/magazine/736-best-us-ai-conferences-for-ctos-in-2026-build-vs-buy-vendor-evaluation-and-peer-intelligence) - [How to Become an AI Engineer](https://www.wearedevelopers.com/magazine/331-how-to-become-an-ai-engineer) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers)
