Senior Network Developer | Tech-Led Systematic Hedge Fund
London | Market-Leading Compensation & Benefits
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
