Make sound technical decisions and clearly communicate their impact, risks, and dependencies
Lead technical activities and incident reviews through influence, without relying on formal line‐management authority
Provide specialist guidance to colleagues and partner teams
Identify and manage risks proactively rather than waiting for incidents, assignments, or escalations
Influence architecture, engineering, and operational decisions beyond the immediate team
Mentor colleagues and promote the reuse of effective tools, patterns, and practices
Remain accountable for the quality and long‐term sustainability of solutions delivered
Key Responsibilities
Technical Ownership and Architecture
Act as the subject‐matter expert for assigned network infrastructure services and components
Maintain a clear and current understanding of component dependencies, service boundaries, data flows, and operational risks
Contribute to the simplification, standardization, and modernization of the technology architecture
Identify, prioritize and reduce technical debt before it affects service stability, security or delivery
Assess the impact of proposed changes on dependent services, controls, capacity, and operational processes
Contribute to platform strategies covering demand, capacity, reusability, and solution design insights
Identify opportunities to retire, consolidate, or simplify components where this reduces cost, risk, or operational complexity
Use proofs of concept, testing, data, and external research to validate technical decisions and challenge assumptions
Service Reliability and Operational Excellence
Take ownership of the reliability and operational health of assigned infrastructure services
Contribute to the achievement of agreed Service Level Agreements and Service Level Objectives
Lead or coordinate monitoring improvements, incident investigation, and problem resolution for assigned services
Identify recurring failure patterns and implement sustainable corrective actions
Ensure that operational documentation, dependency information, support procedures, and recovery documentation remain accurate and usable
Consider service health, customer impact, risk, controls, and lifecycle management from an IT Service Owner perspective
Improve service availability, performance, capacity, security, and resilience through evidence‐based engineering
Escalate material risks, control gaps, capacity constraints, and unresolved dependencies through the appropriate governance channels
Automation and Engineering Delivery
Develop and maintain automation for infrastructure build, configuration,



testing, deployment, and operational support
Promote small, low‐risk and frequent changes through effective continuous delivery practices
Reduce variation between environments and improve the predictability, quality, and auditability of infrastructure changes
Develop reusable tools, automation patterns, and engineering practices for wider adoption across the team and partner teams
Improve development and operational efficiency by eliminating avoidable manual activity
Apply appropriate engineering and scripting approaches to solve problems effectively, regardless of the preferred programming language or technology platform
Ensure that automation is maintainable, appropriately documented and aligned with security and control requirements
Resilience, Risk and Recovery
Own or lead resilience assessments, recovery planning, and disaster recovery exercises for assigned services
Lead role‐swap activities to validate that critical operational knowledge is distributed across the team
Confirm that recovery procedures are practical, tested and supported by appropriate evidence
Translate lessons from production incidents and Post‐Incident Reviews into prioritized and trackable improvements
Contribute to technology risk management, control effectiveness, vendor management, and service continuity activities
Identify single points of failure, unsupported dependencies, and other resilience weaknesses
Ensure that agreed remediation actions are implemented, evidenced, and closed within the required timeframe
Leadership, Collaboration and Continuous Improvement
Provide technical leadership during team, component, and production incident reviews
Demonstrate clear ownership and accountability for assigned services, decisions, and remedial actions
Provide subject‐matter expertise and practical guidance across teams
Build trusted relationships with Infrastructure Engineering, Architecture, IT Service Owners, Risk, Service Management, vendors, and other stakeholders
Lead improvement initiatives that require collaboration across organizational boundaries
Mentor colleagues, share knowledge and encourage inclusive participation in technical discussions
Promote a culture of learning, operational discipline, constructive challenge, and continuous improvement
Identify and pursue opportunities that improve customer outcomes, service resilience, engineering efficiency, and colleague experience
