Manage and optimise monitoring infrastructure using industry-standard tools, ensuring comprehensive visibility across all systems
Plan, communicate, and execute maintenance windows on production systems with minimal disruption to service availability
Triage platform and infrastructural issues with decisiveness and analytical rigour; engage with third-party vendors and support teams as required
Deploy new systems and updates in a staged, risk-managed manner, ensuring safe and incremental rollouts
Survey and adopt best practices in infrastructure and platform management to maintain secure, scalable, and fault-tolerant systems
