Job description

Senior Python Developer (Networking) | Tech-Led Systematic Hedge Fund

A leading, technology-driven systematic hedge fund is seeking a Senior Python or Go Developer to work within their Networking division. 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 or 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
• Complex technical challenges rarely found outside elite trading environments
• Market-leading compensation and benefits

If you enjoy solving infrastructure problems through software and want to operate in a truly engineering-led environment, we’d welcome a confidential conversation.
