Role
Who you are
- Extensive experience administering and growing infrastructure in fast-paced engineering environments
- Deep knowledge of Red Hat Enterprise Linux (RHEL) administration, security hardening, lifecycle management, and troubleshooting
- Hands-on experience configuring, scaling, tuning, and troubleshooting job schedulers (e.g. Slurm) and distributed compute environments
- A strong understanding of network file storage protocols and network optimisation for computational workloads
- Proficiency with container environments and virtualisation infrastructure
- High proficiency with infrastructure automation tools (Ansible, Python, Bash) and infrastructure-as-code practices
- Experience with backup and disaster recovery strategy and implementation
- Experience managing licensed EDA or similar specialist software tooling (e.g. Synopsys) is a strong plus
- Excellent communication skills, with the ability to support both technical and non-technical users and translate complex issues into clear guidance
- Women and other underrepresented groups may be less likely to apply for a role unless they meet all or nearly all of the requirements. If this applies to you, we still encourage you to apply - you may be a great fit, even if you don’t meet every single qualification. We’d love to hear from you
What the job involves
- Riverlane is looking for an experienced Linux administrator to own and grow its core computational infrastructure. This is a hands-on role combining day-to-day administration of the High-Performance Computing (HPC) environment with longer-term planning, automation, and improvement of the infrastructure estate
- You’ll be the primary owner of the HPC cluster and core Linux infrastructure, working closely with IT management and the wider Infrastructure Team to keep systems reliable today while building towards a more resilient, scalable environment for tomorrow
- Administer and maintain the HPC cluster, including compute nodes, storage systems, and networking
- Evaluate and evolve cluster topology, compute node configuration, and hardware resource utilisation as the estate grows
- Lead the deployment, configuration, and troubleshooting of HPC tooling, particularly Slurm—including queue structures and job scheduling policies
- Monitor system performance and ensure high availability of HPC resources using observability tools such as Prometheus; investigate anomalies and outages
- Assess and maintain the network file storage solution for throughput, scalability, and latency
- Maintain, patch, and troubleshoot core Linux infrastructure (RHEL)
- Act as an escalation point for complex technical issues raised by the Riverlane team
- Provide operational upkeep of core infrastructure, including servers, tooling, and licence managers
- Maintain Synopsys EDA tooling, including licence server management, environment configuration, and performance optimisation for electronic design automation workflows
- Provide sound technical support to users of the HPC environment
- Improve self-service capability for users, enabling routine tasks (e.g. restarting VNC sessions and resetting passwords) to be performed without engineering intervention
- Automate routine tasks using scripting and infrastructure-as-code tools (Bash, Python, Ansible)
- Collaborate with the Infrastructure Team to plan and implement improvements to HPC infrastructure
- Own work packages and deliver them within agreed sprint windows
- Build and maintain documentation for systems, processes, and configurations
- Communicate effectively with stakeholders on progress and delivered improvements
- Ensure security and compliance across the HPC estate, including security hardening and lifecycle management
- Maintain and develop the off-site backup strategy, ensuring data integrity, disaster recovery readiness, and compliance with data retention policies

Our take
Whilst quantum computing is known for its precision, the machines used are small and prone to errors. Quantum error correction is the term given to the use of algorithms to fix errors in quantum computing, which Riverlane delivers through its quantum error correction software called Dataflow.
Dataflow was built by what Riverlane describes as the "world’s largest dedicated quantum error correction team". The product consists of proprietary QEC chips, hardware and software that work together to correct billions of errors every second. This will help to deliver a vast improvement upon modern quantum computers which can only perform a few hundred quantum operations before an error occurs.
Riverlane has enjoyed substantial funding which will allow the company to set out on its long-term road map. With such comprehensive expertise and a product that will aid companies and researchers for years to come, Riverlane will no doubt play an integral part of the future of quantum computing.
