Job Description

The organisation has accumulated a fragmented tooling estate with significant underutilisation - tools purchased but never properly deployed or embedded. This role will assess the current tooling landscape, define a target-state tooling strategy, and lead the implementation of automation and observability capabilities that will underpin both the transformation programme and the ongoing operational run state.

Key responsibilities
  • Audit the current network and infrastructure tooling estate, identifying duplication, gaps, and unlicensed/underutilised products
  • Define a target-state tooling strategy covering: network management, observability/monitoring, automation/orchestration, IPAM, and CMDB
  • Design and implement network automation workflows for standard operational tasks (port changes, firewall rule changes, VLAN provisioning)
  • Build out network observability capabilities to provide deterministic visibility across the converged network environment
  • Work with the architecture team to define and implement a CMDB strategy, enabling accurate asset and service dependency data
  • Develop automation to support the transformation programme itself - migration tooling, configuration validation, and audit capabilities
  • Evaluate and rationalise managed service tooling used by the NTT-managed network
  • Provide tooling input into the change management process, enabling automated risk classification and impact assessment
Requirements Technical requirements
  • Network automation: Python, Ansible, or similar automation frameworks

  • Knowledge of ServiceNow integration with network management tooling
  • Familiarity with cloud-native observability tools
  • Scripting for reporting and cost analysis
Soft skills
  • Pragmatic and delivery-focused - able to identify quick wins alongside longer-term capability builds
  • Able to work across infrastructure, operations, and architecture teams
  • Strong documentation skills
  • Capable of training and upskilling operational team members on new tooling
