DevOps Engineer in City of London

Role: DevOps

Location: London

Salary: Up to £250k

We’re looking for a DevOps / Platform Engineer to build, operate, and evolve the infrastructure and tooling used by trading teams and quantitative researchers. The role sits at the intersection of low‑latency colocation networks , containerised applications , and observable, automated infrastructure , with a strong focus on reliability, performance, and self‑service tooling.

Key responsibilities

• Design, deploy, and operate containerised services and internal tools used by trading desks and quants (Python‑based backend services, APIs, data pipelines).
• Maintain and optimise low‑latency systems in colocation environments, collaborating with trading and infrastructure teams on performance and resilience.
• Build and extend network automation workflows to configure and manage trading infrastructure (routers, switches, security, and connectivity).
• Define and implement observability for services and infrastructure using metrics, logging, and alerting (e.g., Prometheus, Grafana, and related tooling).

Key requirements

• Strong backend development experience with Python , including experience building APIs (e.g., FastAPI or similar frameworks).
• Experience with Prometheus ‑style observability: metrics, alerting, and dashboards; familiarity with Grafana is a plus.
• Hands‑on experience with ClickHouse or similar high‑performance data stores is a strong advantage.
• Practical experience with network automation ; Ansible or similar configuration‑management tools are beneficial.
• Experience running and maintaining container orchestration platforms, ideally Nomad ; Kubernetes experience is also acceptable.
• Solid networking knowledge , particularly with Arista EOS and data‑centre networking concepts.
• Some front‑end experience with React or similar frameworks is considered a minor plus.
• Familiarity with Git, CI/CD pipelines, and infrastructure‑as‑code practices (e.g., GitOps, declarative config).
