Application Integration Architect

Role Overview

We are looking for an experienced Application Integration Architect to lead the design and delivery of scalable, high-performance integration solutions across enterprise systems. This role sits at the intersection of architecture, engineering, and business transformation—driving seamless interoperability between platforms while ensuring reliability, security, and performance.

You will work closely with cross-functional teams, including engineering, operations, vendors, and business stakeholders, to define and implement robust integration strategies aligned with enterprise architecture principles.

Key Responsibilities

Design and architect end-to-end integration solutions using modern integration patterns (e.g., event-driven, microservices, API-led connectivity). Translate complex business requirements into scalable technical architectures, specifications, and data flow designs. Develop and govern integration standards, frameworks, and best practices across the organisation. Ensure resilient, secure, and high-throughput data exchange between applications, services, and external platforms. Lead the integration of enterprise systems, including collaboration with third-party vendors and technology partners. Support the onboarding and deployment of new platforms, ensuring seamless integration into the existing ecosystem. Troubleshoot and resolve complex integration issues, including performance bottlenecks and data inconsistencies. Oversee and coordinate integration testing strategies (unit, system, end-to-end) in collaboration with QA and delivery teams. Produce and maintain comprehensive technical documentation, including architecture diagrams, API specifications, and data models. Monitor integration performance and implement optimisation strategies (e.g., caching, asynchronous processing, load balancing). Stay ahead of emerging technologies and continuously evolve the integration landscape.
