The platform scope includes DNS, routing control infrastructure, authentication and identity services, network observability, monitoring, and related network-management capabilities. The role combines people leadership, service ownership, and technical governance, accountable for team capability, technology roadmaps, platform lifecycle, operational performance, security, resilience, automation, and managed-service outcomes. Manages a team of approximately four Linux specialists and managed-service resources supporting a distributed estate of hundreds of Linux systems.
Responsibilities
- Lead, recruit, mentor, and develop Linux engineers and managed-service resources.
- Set clear accountabilities, priorities, and objectives.

- Maintain sufficient technical depth to lead engineering decisions and support major incidents.
- Allocate resources across operational, project, and lifecycle demand.
- Ensure effective knowledge sharing across UK and India locations.
- 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.
- Prioritize investment and demand across Network Engineering, Security, Infrastructure, Architecture, and Operations.
- Govern managed-service and supplier performance.
- Drive standardization and automation using Ansible, scripting, and infrastructure-as-code principles.
- Ensure monitoring, logging, security controls, backup, and support documentation are included in platform builds.
- 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.
- Ensure effective problem, change, capacity, availability, and continuity management.
- Own the platform security roadmap, control outcomes, risk posture, and governance of security exceptions.
- Ensure secure-by-design practices, threat modeling, and appropriate segregation of administrative access.
- Oversee vulnerability remediation, privileged access, secrets, keys, certificates, centralized 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.
- Partner with Network Engineering, Security, Infrastructure, Architecture, Operations, and application teams.
- Ensure technical designs, service documentation, support models, runbooks, and audit evidence are maintained.
- Communicate technical risk, performance, investment needs, and roadmap progress clearly.
- Participate in the Infrastructure Operations on-call rota.
- Provide leadership for priority incidents.
