Integration Developer

About the Role

The Integration Developer is responsible for designing, developing, testing, and maintaining system integrations, APIs, and middleware solutions that connect enterprise applications, databases, cloud platforms, and AI-enabled systems.

This role requires strong integration fundamentals, hands-on experience with MuleSoft and API-led delivery, and the ability to build secure, scalable, and maintainable integration solutions. The ideal candidate can translate business requirements into technical solutions, support integration delivery across enterprise systems, and leverage AI-assisted development tools where appropriate to improve productivity, quality, documentation, and speed of delivery.

Key Responsibilities

• Collaborate with business analysts, IT teams, architects, and stakeholders to understand integration requirements and define technical specifications.
• Design, develop, test, and maintain integration solutions using MuleSoft Anypoint Platform and related middleware technologies.
• Build and maintain APIs for internal and external consumers, ensuring they are secure, scalable, reusable, and performant.
• Implement API-led connectivity patterns, including experience, process, and system APIs where applicable.
• Develop data transformation logic using tools such as DataWeave, JSON, XML, and SQL.
• Implement and maintain data integration processes between on-premises and cloud-based systems, ensuring data consistency, reliability, and integrity.
• Troubleshoot and resolve integration issues across APIs, middleware, applications, and connected systems.
• Monitor integration points and support optimization of integration processes for performance, scalability, and reliability.
• Follow data governance, security, compliance, and secure development standards in integration design and implementation.
• Document integration processes, API specifications, architecture decisions, mappings, configurations, and support procedures.
• Participate in code reviews, contribute to team knowledge sharing, and support junior developers where applicable.
• Stay current with integration trends, MuleSoft platform capabilities, API best practices, and emerging AI-enabled development tools.
• Use AI-assisted development tools, where appropriate, to support API specification, flow generation, DataWeave mapping, testing, documentation, troubleshooting, and iterative development activities.
• Support integrations that allow AI agents or automation workflows to securely access enterprise systems, APIs, and data sources, while following governance and compliance requirements.
