The Role
\n
You will work across software engineering, infrastructure and production operations to improve the reliability, performance and scalability of a global trading platform. This is a development-first reliability role: you will write production-quality automation and tooling, improve observability, streamline deployments and help eliminate classes of operational failure.
\n
You will collaborate closely with trading-system engineers, quant researchers, infrastructure engineers and platform teams in a fast-moving, low-latency environment.

- Design, build and maintain automation, deployment and configuration tooling for trading and research infrastructure.
- Develop internal platforms and services using Python and/or Go.
- Build and improve CI/CD pipelines, release workflows, environment management and deployment automation.
- Operate and enhance Linux-based production environments across on-premises data centres and cloud infrastructure.
- Build observability solutions including metrics, logging, tracing, alerting, dashboards and automated remediation.
- Investigate and resolve complex production incidents, performing deep technical root-cause analysis.
- Improve system resilience through redundancy, failover design, capacity planning and proactive performance tuning.
- Use Infrastructure as Code to provision and manage infrastructure, including Terraform and/or Ansible.
- Support containerised workloads and Kubernetes-based platforms where appropriate.
- Work with networking, storage and compute teams to optimise low-latency, high-throughput systems.
- Participate in an on-call rotation and drive improvements through post-incident reviews and automation.
- Partner with engineering teams to establish best practices for reliability, testing, deployment and operational excellence.
