Experience building application-to-application integration orchestration solutions.
Solid understanding of JSON, XML, and transformation patterns.
Experience with middleware/integration concepts (message-driven design, orchestration, idempotency, retries, correlation IDs).
Experience implementing complex orchestrations with automatic re-processing (retry/replay, failure handling, re-queue patterns).
Familiarity with authentication and security patterns: OAuth2, API keys, token-based auth.
Experience with logging, monitoring, error handling, and operational troubleshooting.

Responsibilities

Design, develop, and support enterprise integrations using Python (services, orchestration components, automation utilities).
Build and consume RESTful APIs for system-to-system communication.
Develop data transformation, validation, enrichment, and orchestration logic using JSON/XML payloads.
Build application-to-application integration orchestrations, including resilient workflows and dependency coordination across systems.
Implement and support event-driven and batch integrations using JMS (queues/topics), including message processing and recovery patterns.
Implement automated reprocessing patterns (retry, replay, dead-letter / suspended queue handling) to reduce manual intervention and improve stability.
Troubleshoot, debug, and resolve integration issues across Dev, SIT, UAT, and Production environments.
Implement strong logging, monitoring, and alerting practices; ensure integrations are supportable in production with clear runbooks and operational checks.
Participate in release execution and deployment readiness activities (checklists, verification, rollback awareness), partnering with DevOps/ops teams as needed.
Work closely with architects, product owners, QA, and DevOps to deliver reliable solutions.
