Integrate AI and data capabilities into applications and internal tools.
Collaborate closely with AI engineers, data engineers, and product stakeholders to deliver cohesive end-to-end solutions.
Apply robust engineering practices across development, testing, deployment, monitoring, and observability.
Optimise applications for performance, reliability, scalability, and security.
Contribute to architectural decisions across application, platform, and integration layers.
Troubleshoot and resolve issues across the stack in live environments.
Document systems, patterns, and best practices to support maintainability and knowledge sharing.
