What you will do
Leadership and Team Management
Lead, recruit, mentor and develop Linux engineers and managed-service resources, building sustainable capability and succession.
Set clear accountabilities, priorities and objectives and foster a culture of ownership, collaboration, technical excellence and continuous improvement.
Maintain sufficient technical depth to lead engineering decisions, challenge designs and support major incidents, while developing Senior Engineers as the primary technical authorities for assigned platforms and services.
Allocate resources across operational, project and lifecycle demand and ensure effective knowledge sharing across UK and India locations.
Service Ownership, Strategy and Governance
Own the strategy, roadmap and service lifecycle for Linux-based network infrastructure and associated services.
Set platform standards, reference architectures, operating procedures and governance for technical exceptions.
Own service performance, availability, capacity, continuity, recoverability and operational readiness outcomes.
Manage platform currency, technical debt, upgrades, obsolescence and decommissioning plans.
Prioritise investment and demand across Network Engineering, Security, Infrastructure, Architecture and Operations.
Govern managed-service and supplier performance, including service quality, delivery commitments and improvement actions.
Engineering, Resilience and Operational Excellence
Drive standardisation and automation using Ansible, scripting and infrastructure-as-code principles to reduce manual effort and operational risk.
Ensure monitoring, logging, security controls, backup and support documentation are included as part of every platform build.
Define measurable objectives for availability, capacity, recoverability, vulnerability remediation, lifecycle risk and automation coverage.
Ensure critical services have tested backup, restoration, failover, continuity and disaster-recovery arrangements.
Lead major-incident response, risk escalation and stakeholder communications when required.
Ensure effective problem, change, capacity, availability and continuity management across the service portfolio.
Security, Compliance and Risk
Own the platform security roadmap, control outcomes, risk posture and governance of security exceptions.
Ensure secure-by-design practices, threat modelling and appropriate segregation of administrative access are applied.
Oversee vulnerability remediation, privileged access, secrets, keys, certificates, centralised audit logging and software repository security.
Ensure the team can support security incidents while preserving relevant operational and forensic evidence.
Ensure compliance evidence is complete, repeatable and available for audit and regulatory review.
Collaboration and Documentation
Partner with Network Engineering, Security, Infrastructure, Architecture, Operations and application teams to align platform priorities and dependencies.
Ensure technical designs, service documentation, support models, runbooks and audit evidence are maintained throughout the lifecycle.
Communicate technical risk, performance, investment needs and roadmap progress clearly to technical and senior leadership audiences.
Operational Support
Participate in the Infrastructure Operations on-call rota and provide leadership for priority incidents.
