• Contextual Data Transformation: Execute complex data mappings, conversions, and transformations migrating data from legacy platforms to modern architectures.

• API-Led Connectivity & Modernization: Transition legacy file-based transfers into modern, secure RESTful APIs and microservices contracts.

• Streaming & Event Messaging: Integrate and process high-volume datasets using Kafka for real-time asynchronous event flows.

• Database & SQL Optimization: Write and optimize PL/SQL / SQL queries to extract, transform, and validate transactional data integrity across migration streams.

• Containerization & Shell Automation: Deploy and support middleware nodes within OpenShift containerized environments; author Unix/Linux Shell scripts for CI/CD automation and pipeline maintenance.

Required Qualifications

• IBM ACE & MQ Expertise: Proven hands-on development experience with IBM App Connect Enterprise (ACE), IBM Integration Bus (IIB), ESQL, and IBM MQ.

• Banking / Payments Domain Knowledge: Direct background working with core Deposits, Banking Payments, or ACH (Automated Clearing House) transaction workflows.

• APIs & Modern Infrastructure: Hands-on experience creating RESTful APIs and operating within containerized environments (OpenShift).

• Scripting: Proficiency in writing and maintaining Unix/Linux shell scripts for operational automation.

• Terms: Must be eligible for direct W2 employment (Strictly No C2C / No Third Parties).

Why Apply?
