• Coordinate all scheduled maintenance activities including platform upgrades, security patches, and configuration changes, ensuring changes are properly assessed, tested, approved, and documented prior to implementation

• Investigate API-related issues including HTTP errors, authentication failures, network connectivity problems, and performance degradation by analysing application logs, monitoring dashboards, and diagnostic data

• Support API onboarding, access provisioning, integration testing, and configuration changes in collaboration with application owners, infrastructure teams, and cloud service providers

• Ensure the platform is operated in compliance with applicable government ICT security policies; coordinate vulnerability assessments, penetration testing, certificate renewals, and remediation activities

• Prepare periodic operational reports on platform availability, incident trends, service performance, and vendor deliverables, and recommend improvements to monitoring, processes, and documentation
