Senior HPC System Administrator

About Us:

Established in 2002, General Fusion is a global leader in the race to commercialize clean fusion energy. We are pursuing a uniquely practical approach, Magnetized Target Fusion, and aim to provide zero-carbon fusion power to the grid in the early to mid-2030s. Today at our state-of-the-art labs in Richmond, BC, we’re operating a groundbreaking fusion demonstration machine called Lawson Machine 26 (LM26), designed to achieve transformational technical milestones and accelerate General Fusion’s technology to commercialization. Our path to market is funded by a global syndicate of leading energy venture capital firms, industry leaders, and technology pioneers. Learn more at www.generalfusion.com.

Position Overview:

General Fusion research relies heavily on experimental data and computer simulation to design and operate its experimental devices. We’re seeking a versatile technical lead to support the infrastructure that empowers our scientists, including managing our High-Performance Computing (HPC) environment, and contributing to our research data infrastructure.

As the HPC Administrator, you will ensure our computer cluster is stable, optimized, and serve the needs of the science teams. The system runs Rocky Linux and comprises 70 computer nodes and 1PB of storage. This role will help shape the computational research infrastructure at a scientific R&D startup. You'll have opportunities to propose architectural changes, reduce complexity, and build out systems that directly accelerate scientific discovery. If you're energized by working at the intersection of infrastructure, data, and scientific computing, this role is for you.

Responsibilities:

· Act as the primary source of HPC expertise within General Fusion

· Cluster administration, including maintaining the OS and software environment, resource provisioning and allocation, managing the job scheduler (SLURM), user account management, and monitoring system health and performance

· Provide training and support for HPC users

· Collaborate with IT on networking and physical infrastructure; ensure alignment with IT policies, security standards, and corporate governance requirements, including applicable SOX controls

· Design high-performance data architectures for storage, retrieval and analysis of complex research datasets; contribute to data versioning, result reuse, and metadata cataloging systems

· Proactive monitoring of system health and performance, across both compute nodes and data pipelines

· Seek opportunities to consolidate tooling and reduce operational overhead

· Act as a bridge between traditional HPC computing and modern data platform patterns, helping integrate simulation data with experimental data systems

· Maintain and improve technical documentation

· Contribute to strategic planning and decision-making to help drive the evolution of General Fusion’s data systems

Requirements:

· Degree in Computer Science, Computer Engineering, Engineering Physics or related field

· 5+ years professional experience in an applied R&D environment, working in scientific computing and/or research data infrastructure.

· 2+ years of experience managing HPC clusters, with a solid understanding of Infini

Band, MPI/parallel computing concepts, storage architectures, and workload scheduling (SLURM)

· Experience across the modern Linux systems lifecycle, including OS administration (e.g. Rocky, Ubuntu, RHEL), container orchestration (Apptainer/Singularity, Docker), and declarative infrastructure to ensure environment reproducibility

· Proficiency in low-level resource management (CPU/memory/IO) and system-level performance tuning

· Experience implementing alerting, logging, and monitoring tools to track system health and performance (Prometheus, Grafana, or similar)

· Excellent verbal and written communication skills; experience writing technical documentation

· Proactive and collaborative, you’re comfortable taking ownership, proposing solutions, and can act as a bridge between development, IT, and research teams

Preferred:

· Experience in a multidisciplinary research or R&D environment, with a background in physics, math, or advanced analytics

· Experience in platform or data engineering, specifically building systems that serve technical users

· Good understanding of standard protocols like NFS, SMB, LDAP, DHCP and NTP

· Database experience, including NoSQL (MongoDB)

· Experience with big data tools and frameworks, such as modern 'lakehouse' patterns (e.g. Spark, Iceberg, Polars), high-performance analytical formats (Parquet, HDF5), and distributed OLAP engines (e.g. Click

House, DuckDB)

· Experience with data versioning systems (e.g. DVC, LakeFS) and reproducible research best practices

The typical hiring range for this position is $126,000 – $154,000. General Fusion considers many factors when determining total compensation, including job-specific or highly specialized knowledge, skills and experience, proficiency, job location and internal equity.

What We Offer:

· Flexible hours

· Four weeks’ vacation

· Comprehensive benefits package

· RRSP Contribution – No Employee Match Needed!

· Support for professional development

· Great company culture – social events, food trucks, bike rides, Sun Run, etc.
