• Proven experience designing and implementing integration solutions connecting disparate systems, applications, and data sources across on-premises and cloud environments
• Strong understanding of integration patterns and architectural styles (e.g., point-to-point, hub-and-spoke, event-driven, pub/sub, ESB, iPaaS)
• Hands-on experience with API design and development, including RESTful services, SOAP, and/or GraphQL
• Working knowledge of API security standards and protocols (OAuth2, JWT, SAML, API keys) and best practices for versioning, throttling, and error handling
• Experience with enterprise integration platforms/tools (e.g., MuleSoft, Apigee, Kong, Workato, BizTalk, Boomi, or equivalent)
• Experience with at least one major cloud platform (Azure, AWS, or GCP), including cloud-native architecture and deployment practices
• Solid understanding of data mapping, transformation, and orchestration techniques across heterogeneous systems
• Experience managing the full software development lifecycle (SDLC), including CI/CD pipelines, testing strategies, and deployment across multiple environments (Dev, Test, UAT, Production)
• Strong analytical and troubleshooting skills, with the ability to diagnose and resolve complex integration and performance issues
• Excellent communication skills, with the ability to translate business requirements into technical solutions and explain them to both technical and non-technical stakeholders
• Demonstrated ability to create clear technical documentation, including architecture diagrams, specifications, and data mapping references
• Experience leading or mentoring junior developers, with a collaborative approach to working across cross-functional teams
