Job description

Responsibilities

• We’re looking for a Staff Network Systems Engineer to help drive the transition of our global network infrastructure from manually managed and inconsistent configurations to a standardised, version-controlled and increasingly automated operating model
• This hands-on staff-level individual contributor will establish Infrastructure as Code practices, reusable automation, automated validation and safe delivery pipelines
• The role will reduce configuration drift, make changes repeatable and auditable, and help the wider team adopt modern software-engineering practices
• Working across network engineering, security, architecture and platform teams, you’ll help frame and influence technical direction, create practical standards and guardrails, and remain actively involved in enterprise network engineering and operational delivery
• Assess the network estate, toolchain and operational workflows; identify sources of configuration variance, manual effort and change risk; and help define a phased modernisation roadmap
• Establish the Infrastructure as Code operating model, including the authoritative source of truth, configuration standards, source control, peer review, testing, release governance and secure handling of credentials
• Build reusable automation using object-oriented or comparable programming languages such as Python and Go (Golang), together with Terraform, Ansible, APIs and configuration-management tooling
• Develop CI/CD pipelines with automated linting, testing, intended-state validation, drift detection, policy checks, approvals, controlled rollout and reliable rollback patterns
• Partner with engineering, architecture and security teams to translate network intent into version-controlled implementations and influence reference architectures, standards, lifecycle plans and service roadmaps
• Lead the safe migration of existing services into the automated model while remaining hands-on during complex delivery, business-as-usual operations, critical changes, troubleshooting and major incidents
• Participate in technical authority and design-review forums, mentor engineers, and ensure automation becomes a sustainable team capability rather than knowledge held by a single specialist
• This is a staff-level role combining hands-on engineering with technical leadership across a global network environment. You’ll build production automation, guide others and remain engaged with operational delivery
• The objective is to establish an engineering system the team can operate and improve over time while maintaining secure, resilient and supportable network services
• Success will be demonstrated through:
• Increased coverage of network infrastructure managed through version-controlled automation
• Reduced configuration drift, manual intervention, operational toil and dependency on individual subject-matter experts
• Shorter and more predictable change lead times, with improved auditability, validation and rollback confidence
• Lower change-failure rates, maintained service reliability and faster recovery from configuration-related incidents
• Sustained adoption of automation standards, modules and delivery practices across the wider engineering team
