Introduction

IBM’s greatest invention is the IBMer. We believe that through the application of intelligence, reason and science, we can improve business, society and the human condition, bringing the power of open hybrid cloud and AI strategies to life for our clients and partners around the world.

Restlessly reinventing since 1911, IBM is one of the world’s largest technology and consulting organisations. Our teams support public and private sector clients to modernise complex enterprise platforms using cloud, data, integration and automation technologies.

IBM Australia is seeking an experienced Integration Architect to design and deliver enterprise‑scale integration solutions on AWS, supporting major transformation, cloud migration and platform modernisation programs across asset‑intensive and regulated industries.

Role Overview

As an Integration Architect, you will lead the architecture, design and delivery of enterprise integration solutions across cloud, hybrid and on‑premise environments. Your focus will be on enabling secure, scalable, API‑led and event‑driven integration between enterprise platforms, cloud‑native applications, SaaS products and operational systems.

You will work across AWS cloud environments, supporting integrations involving ERP, asset management platforms, GIS, IoT/telemetry systems, data platforms and external partners. The role operates at both a strategic architecture and hands‑on delivery level, contributing to national‑scale public and private sector programs.

Cloud Migration, Modernisation & Enablement

• Support enterprise migration programs by defining integration architectures for re‑host, re‑platform and re‑architect initiatives

• Simplify and modernise integration landscapes using cloud‑native patterns

• Establish CI/CD pipelines for integration workloads, enabling automated build, test and deployment

• Embed DevSecOps practices across integration solutions

• Drive observability, logging and operational health across integration platforms

Governance, Security & Standards

• Define integration governance frameworks, standards and design guardrails
