Job description

Hello Folks,
Please find the below requirement and let me know your interest?
Job Title: Python Integration Developer
Location: Hanover, MD — Hybrid (3 days/week onsite)
Experience Level: Mid–Senior
It’s a W2 Role
Job Summary
We are seeking an experienced Integration Developer with strong Python development skills to build and support enterprise integrations across cloud platforms and internal systems. This role focuses on API-based integrations, application-to-application orchestration, and event-driven messaging (JMS) with a strong emphasis on reliability, automated reprocessing, and production support readiness across Dev/SIT/UAT/Prod environments.
Key Responsibilities
Integration Development & Orchestration
  • 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.
Messaging / Event-Driven Integration
  • 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.
Operational Readiness & Support
  • 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.
Collaboration & Quality
  • Work closely with architects, product owners, QA, and DevOps to deliver reliable solutions.
  • Participate in code reviews and follow best practices for security, performance, maintainability, and documentation.
Required Skills & Qualifications
  • Strong hands-on experience with building APIs with Python using FLASK or FASTAPI Frameworks.
  • Strong experience building/consuming REST APIs and Orchestrations working with AWS/Azure services like Amazon API Gateway, Lamda, Step Function, Amazon S3, Amazon SQS, MQ, Event Bridge, MSK (Managed Streaming for Apache Kafka), CloudWatch.
  • 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.
  • Strong problem-solving, debugging, and root-cause analysis skills.
Preferred / Nice-to-Have
  • Experience with integration platforms such as MuleSoft, OIC, Boomi, or similar.
  • Experience integrating with ERP/HCM systems such as Oracle Fusion and PeopleSoft.
  • Experience with CI/CD pipelines and release promotion across environments.
  • Understanding of event-driven architectures and messaging systems beyond JMS (e.g., CDC, platform events).
  • Experience supporting production integrations, hypercare, and operational handoff practices (runbooks, monitoring, escalation readiness).
  • Bachelor’s degree in Computer Science, Engineering, or equivalent experience.
