• Production Support & Monitoring: Monitor integration workflows in production, respond to support tickets, and perform troubleshooting. This role may require 24/7 on‑call support for production‑critical issues, ensuring rapid incident response and resolution.
• Cross‑Functional Collaboration: Partner with stakeholders (IT, operations, finance, external vendors) to gather requirements, manage expectations, and drive integration roadmaps.
• Mentoring & Documentation: Mentor less‑senior engineers, maintain up‑to‑date integration documentation and runbooks, and develop training materials.
