Senior Storage Engineer (City of London)

I'm working on behalf of a leading global quantitative investment firm that’s seeking a Senior Storage Engineer to join their world-class infrastructure team. This role sits at the core of their high-performance research and trading operations, supporting one of the most advanced compute environments in finance.

You’ll play a pivotal role in engineering and scaling large-scale storage platforms for high-performance computing (HPC) and AI/ML research. This is a fantastic opportunity for a technically outstanding engineer looking to work in a collaborative, low-ego environment where infrastructure is truly seen as a strategic asset.

What You’ll Do:

• Design, build, and support high-performance storage systems (e.g., NFS, S3, CEPH, GPFS, Lustre, VAST, WEKA, DDN)
• Collaborate closely with Quant Researchers and AI/ML teams to translate their workloads into scalable storage infrastructure
• Optimize performance across Linux kernel , storage , and networking stacks
• Drive benchmarking, tuning, and capacity planning for large-scale, data-intensive workloads
• Implement and maintain DevOps tooling (Terraform, Ansible, GitLab CI/CD, Jenkins)
• Lead PoCs for new storage technologies and present results to technical leadership
• Support observability via Grafana, Prometheus, Splunk , and related platforms
• Contribute to containerization efforts with Docker and Kubernetes (preferred)

What We’re Looking For:

• 8+ years of experience in storage systems administration and infrastructure/platform engineering
• Deep knowledge of storage protocols (Posix FS, NFS, CIFS, S3) and high-performance network architectures (ROCE, Infiniband, kernel bypass)
• Strong understanding of Linux performance tuning , particularly in HPC or ML/AI contexts
• Programming/scripting experience in Python , Golang , or similar languages
• Familiarity with modern observability and monitoring tools (Grafana, Prometheus, Splunk)
• Experience supporting AI/ML modelling environments is highly desirable
• Knowledge of container and orchestration technologies (Docker, Kubernetes) is a plus
• Proactive, collaborative, and passionate about building world-class infrastructure

This is a rare chance to join a firm that treats infrastructure as a first-class citizen. If you thrive in high-performance environments and want to work alongside some of the brightest minds in quantitative finance and research, let’s connect.
