The role

We're hiring a Network Automation Engineer to help transform how networking is delivered across our global infrastructure.

You'll sit at the intersection of networking and software engineering, building the automation frameworks, APIs and tooling that make our network scalable, self-service and production-ready. This is a hands-on role where you'll design and ship systems that power large-scale compute and research environments.

Key responsibilities of the role include:

• Building and evolving automation frameworks for network provisioning and lifecycle management
• Developing infrastructure-as-code solutions using Python, Ansible, Terraform and Jinja2
• Integrating network automation into CI/CD pipelines for reliable, repeatable deployments
• Creating APIs and self-service tooling for engineering teams
• Implementing observability and telemetry solutions for performance and reliability
• Partnering with Network, Platform and Security teams to deliver resilient, scalable systems
• Contributing to incident response and production reliability

This is an opportunity to redefine how modern networks are managed through clean engineering, automation-first thinking and systems built to scale.

Do you have experience in Terraform?, The ideal candidate will have the following skills and experience:

• Confident with Python and solid engineering fundamentals across testing, version control and CI/CD
• Deep understanding of networking fundamentals, including routing, switching, firewalls and protocols
• Experience with infrastructure-as-code and automation tools such as Ansible, Terraform and Jinja2
• Familiarity with Docker and Kubernetes
• Exposure to monitoring, observability or telemetry in distributed systems
• Pragmatic problem solver who can operate in ambiguity and take ownership
• Comfortable working in collaborative, fast-paced engineering teams

The following skills are desirable, but not essential:

• Experience with event-driven architectures, such as Kafka and RabbitMQ
• API design or platform engineering experience
• Knowledge of service discovery, secrets management or policy-as-code
• Understanding of large-scale data centre networking, for example with Cisco, Arista, segment routing or multitenancy
• Contributions to open-source networking or automation projects

• Highly competitive compensation plus annual discretionary bonus
• Lunch provided (via Just Eat for Business) and dedicated barista bar
• 30 days' annual leave
• 9% company pension contributions
• Informal dress code and excellent work/life balance
• Comprehensive healthcare and life assurance
• Cycle-to-work scheme
