Integration Architect/API Architect 

Tasks 

• Advise clients on selecting and deploying integration and API management platforms (e.g., Kong, Apigee, MuleSoft, Gravitee) and define end-to-end integration architectures (API-first, microservices, cloud-native, event-driven)


• Design and implement event-driven and asynchronous integrations using technologies such as Kafka / Pub/Sub / EventBridge, including A2A automation via lightweight APIs and workflow engines


• Modernize legacy integrations (SFTP, ETL, monolithic brokers) into scalable, resilient API/event-based solutions, delivering migration approaches and target-state designs


• Operate and improve platforms in hybrid/cloud environments, ensuring security, reliability, scalability, and implementing CI/CD + GitOps, observability, and SLA/SLO standards


• Establish API governance and best practices, track global API/integration KPIs (usage, performance, adoption, cost), and leverage AI/agentic tools (incl. MCP) to automate discovery, documentation, testing, and contract validation
