Contextual Data Transformation: Architect and execute complex data mappings and business logic transformations to support the migration from the legacy platform.
-
API-Led Connectivity: Drive modern infrastructure updates by transitioning legacy, file-based batch transfers into real-time, API-based integrations.
-
Streaming & Messaging: Integrate and process high-volume, asynchronous, real-time datasets utilizing Apache Kafka.
-
Database Engineering: Construct and tune complex PL/SQL queries to safely retrieve, transform, and validate data integrity throughout the conversion lifecycle.
-
Containerized Orchestration: Support deployments and maintain enterprise middleware nodes inside a Red Hat OpenShift environment.
-
Automation: Develop and maintain robust Unix/Linux shell scripts for background automation and operational support.
Required Skills & Experience
-
IBM ACE Mastery: 5+ years of dedicated, hands-on development experience with IBM App Connect Enterprise (ACE).
-
Conversion Logic: Direct, proven experience handling complex middleware system conversions involving heavy contextual data transformation.
-
Modern Infrastructure: Solid hands-on experience working within containerized Red Hat OpenShift environments.
-
Data Streaming: Strong proficiency with Kafka integration for real-time messaging pipelines.
-
Database Expertise: Advanced SQL and PL/SQL development skills, specifically for data retrieval, structural transformation, and rigorous validation.
-
API Development: Deep background building, testing, and consuming secure RESTful APIs.
-
Scripting: Clean proficiency in Unix/Linux shell scripting for system automation.
