Senior Network Automation Engineer (NetDevOps)
London | Tech-Led Systematic Hedge Fund | Market-Leading Compensation
A leading, technology-driven systematic hedge fund is seeking a Senior Network Automation Engineer to help scale and modernise a cutting-edge on-premise datacentre and research platform. This is a highly technical role focused on building the automation, tooling, and guardrails that power safe, repeatable outcomes across high-performance infrastructure.
You’ll operate at the intersection of networking and software engineering, playing a key role in transforming network intent into production-grade automation within a fast-moving, engineering-led environment.
The Role
You will design and evolve the network automation ecosystem that underpins the firm’s datacentre fabrics, enabling scalable, resilient infrastructure through code-driven practices.
Key responsibilities include:
- Architecting and enhancing the network automation framework, including source of truth, templating, validation, and change control
- Building idempotent automation to provision and operate datacentre networks at scale
- Capturing network intent as code with strong peer review and quality controls
- Integrating with vendor APIs and SDKs (e.g. Arista EOS) to streamline operations
- Instrumenting networks with telemetry, alerting, and SLO-driven remediation
- Partnering with network and platform engineers to convert design into automated workflows
- Delivering incremental, well-tested improvements that prioritise safety and reliability
- Championing NetDevOps best practices and knowledge sharing across the team
- Monitoring industry trends and identifying opportunities for practical adoption
What We’re Looking For
- Advanced Python skills with experience building production-grade tools and services
- Go experience preferred for high-performance tooling
- Strong Ansible expertise and familiarity with structured data models (YAML/JSON)
- Solid Git workflows including branching, pull requests, and versioning
- Observability experience (Prometheus, Grafana, logging, tracing)
- Familiarity with source-of-truth platforms such as NetBox or Nautobot
- Strong Linux networking knowledge (DNS, DHCP, iptables) and Bash scripting
- Experience with workflow orchestration tools (e.g. Temporal)
- Network validation and testing frameworks such as pyATS or NAPALM
- Containers and orchestration (Docker, Kubernetes)
- Secure configuration and secrets management (Vault, PKI best practices)
- Exposure to datacentre fabrics, QoS, and high-performance networking is advantageous
Why Join?
- Work within a technology-first hedge fund that invests heavily in infrastructure
- Direct impact on a rapidly expanding, high-performance research and trading platform
- Collaborative, low-ego engineering culture
- Complex technical challenges rarely found outside elite trading environments
- Market-leading compensation and benefits
