About the role

• Compile and convey the configuration and development prerequisites that third‑party systems must deliver for System Integration Testing readiness, liaising directly with their owners.
• Execute a concise suite of HTTP based API smoke tests (REST, SOAP, RPC etc.), troubleshoot anomalies, and escalate unresolved gaps to third‑party counterparts and the Solution Architect.

• Maintain clear traceability: update Jira and Confluence records for change requests and for SIT preparations.
• Drive continuous improvement by converting lessons learned into reusable templates — covering change‑request assessments, SIT readiness checklists, and smoke‑test scripts — so future integrations follow streamlined, standardised practices.
