You will also support the onboarding of applications, monitor platform performance and availability, troubleshoot integration issues, and manage platform maintenance activities such as patching and upgrades. Working closely with internal and external stakeholders, you will provide technical guidance on integration design, promote consistent standards and best practices, and support security reviews, audits, vulnerability remediation, and project delivery.

A good understanding of API Gateway concepts, application security, access control, secure file transfer, and event-driven architecture is important, together with experience operating in enterprise or cloud environments.

Experience with technologies such as MuleSoft, Azure API Management, Kafka, or similar integration and messaging platforms would be advantageous. Exposure to identity and access management (IAM) solutions and established integration standards is also beneficial. Strong troubleshooting, problem-solving, and stakeholder communication skills are required for success in this role.
