Technical Leadership & Governance Produce and maintain knowledge bases, technical documentation, and operational resources. Validate and remediate solution compliance in line with organisational and regulatory requirements. Identify risks, issues, and dependencies and contribute to the design of secure, scalable infrastructure and platforms.
