IDnow is seeking a highly skilled IT Integration Engineer with strong software development capabilities and emerging expertise in AI-driven integration. In this role, you will architect, implement, and optimise integrations across cloud platforms, data systems, and application environments. You will also design and operationalise AI workflows—leveraging automation, machine learning services, and intelligent data pipelines—to enhance business processes and system interoperability. You will work closely with cross‑functional teams to implement automation, build reliable integration processes, integrate data services, and deliver robust infrastructure-as-code solutions.

Key Responsibilities

• Design and maintain scalable integrations across enterprise systems, SaaS platforms, and internal applications.
• Build and enhance GitLab based CI/CD pipelines to support application integration and infrastructure automation.
• Use Terraform (or other Infrastructure as Code tools) to design and provision cloud infrastructure—primarily on AWS.
• Develop automation scripts and workflows to reduce manual operational overhead and improve reliability.
• Integrate machine learning and approved AI‑based services into operational workflows and data pipelines.
• Implement data integration pipelines using APIs, event‑driven architectures, and messaging systems.
• Develop and maintain AI‑driven middleware using Node.js and/or Python to enhance decisioning, routing, or workflow logic.
• Manage, deploy, and troubleshoot MCP (Node.js‑based) servers used for programmatic control, middleware, or message processing.
• Collaborate with software engineers, data teams, and cloud engineers to deliver end‑to‑end integration solutions.
• Ensure integrations are secure, well‑documented, and compliant with organisational standards.
• Write clean, modular, well‑tested code following engineering best practices.
• Participate in code reviews, architectural discussions, and continuous improvement efforts.
• Monitor, tune, and optimise system performance and reliability across integration layers.

Preferred Experience

• 3-5 years in an IT Integration, DevOps, or Software Engineering role.
• Strong hands‑on experience with GitLab, including pipeline creation, runners, artifacts, and CI/CD orchestration.
• Proficiency with Infrastructure as Code, particularly Terraform, and experience deploying resources in AWS.
• Solid experience in automation using scripting languages such as Python, Bash, or JavaScript/Node.js.
• Experience building and maintaining data integrations (APIs, webhooks, ETL, messaging queues, or event‑driven systems).
• Working knowledge of MCP (Node.js) servers, including configuration, extension development, and deployment.
• Solid understanding of AI/ML concepts, model APIs, prompt engineering, and integrating LLMs into backend services.
• Strong backend development experience (Node.js, Python, or similar).
• Knowledge of networking, identity/access management, and security best practices.
• Familiarity with containerisation (Docker) and orchestration (Kubernetes) is a plus.
• Excellent communication, documentation, and cross‑team collaboration skills.
