Role Objectives
- Strategic Technical Leadership
- End-to-End Traceability: Trace transaction flows from the API Gateway (API Connect) through the Enterprise Service Bus (ACE) to the backend Microservices (Spring Boot).
- Root Cause Analysis (RCA): Lead deep-dive investigations into middleware failures, including message losses in MQ, synchronization errors in ACE, or JVM crashes in Spring Boot.
- Platform Governance: Ensure the stability of integration components running on Red Hat OpenShift, focusing on optimal resource (CPU/Memory) allocation and pod scaling.
- Security Enforcement: Manage and troubleshoot security protocols such as Mutual TLS (mTLS), OAuth2, and JWE/JWS within the integration layer.
Technical Responsibilities
- IBM Cloud Pak for Integration (CP4I)
- App Connect Enterprise (ACE): Troubleshoot message flows, ESQL logic errors, and adapter connectivity issues (SAP, Database, File).
- IBM MQ: Manage queue managers, resolve channel retries, and investigate dead-letter queues or message persistence issues.
- API Connect: Resolve issues related to API definitions, security policies, and Gateway (DataPower) latency.
- Backend Microservices (Spring Boot)
- Performance Tuning: Analyze JVM thread dumps and heap dumps to resolve memory leaks or high CPU utilization in microservices.
- Connectivity Debugging: Troubleshoot Spring Boot integration with databases (JPA/Hibernate) and external messaging systems (JMS/Kafka).
- Log Aggregation: Utilize ELK/Splunk to correlate logs across multiple microservices to identify points of failure in a distributed architecture.
Technical Skill Set
- Integration Platforms: Mastery of IBM CP4I (specifically ACE, MQ, and API Connect).
- Development Frameworks: Advanced knowledge of Java and Spring Boot (Spring Integration, Spring Cloud).
- Containerization: Expert-level proficiency in Red Hat OpenShift and Kubernetes.
- Protocols & Standards: Expert understanding of REST, SOAP, JSON, XML, AMQP, and MQTT.
- Monitoring Tools: Hands-on experience with IBM Instana, Dynatrace, or Prometheus/Grafana.
Qualifications
- Experience: 5+ years in Middleware or Integration Support.
- Location: Currently residing in KSA.
- Complex Problem Solving: Ability to debug asynchronous communication patterns and distributed transactions.
- Education: Bachelor’s degree in Computer Science, Software Engineering, or a related field.
- Certifications (Preferred): IBM Cloud Pak for Integration Specialist, Red Hat Certified Specialist in OpenShift Administration.
Key Performance Indicators (KPIs)
- Integration Uptime: Achieving 99.99% availability for critical middleware components.
- L2 Resolution Rate: Maximizing the number of integration issues resolved without escalation to L3 Engineering.
- MTTR: Reducing the time taken to identify and fix failures in the message delivery pipeline.
