Job Summary
We are seeking an experienced Integration Support Engineer with 2+ years of experience in enterprise integration and production support. This role will act as the complete owner of the customer support board — managing, triaging, and resolving support tickets end to end while coordinating with engineering, product, and implementation teams. The ideal candidate has strong hands-on experience with Boomi or another iPaaS platform, deep working knowledge of databases and REST APIs, and a track record of rigorous testing and validation. Experience with Intapp Integration Builder is a plus.
Work Hours: 6:00 PM – 5:00 AM, with flexible breaks during the shift.
Key Responsibilities
• Own the customer support board end to end — triaging incoming tickets, managing priority and status, and driving each issue through to resolution.
• Serve as the frontline point of contact for customers on integration issues, providing clear, timely communication throughout the life of a ticket.
• Debug and troubleshoot integrations built on Boomi or other iPaaS platforms, performing root-cause analysis and resolving incidents within SLAs.
• Write, optimize, and troubleshoot SQL queries against production and staging databases for data validation, reconciliation, and issue investigation.
• Work extensively with REST/SOAP APIs, FTP/SFTP, and data formats such as JSON and XML to diagnose and resolve integration failures.
• Test and validate reported issues, including reproducing defects, verifying fixes, and confirming resolution before closing tickets.
• Participate in integration design and enhancement work, contributing to the build and improvement of existing integration processes.
• Take up new development and change requests, following SDLC practices — design, build, test, and deploy — to release changes safely to production.
• Work across internal teams — engineering, product, and implementation — to triage incoming issues, determine ownership, and coordinate resolution.
• Collaborate closely with engineering, product, and implementation teams to resolve both technical issues (database, integration, and server-side) and business/process issues.
• Stay flexible and continuously build cross-functional knowledge, since resolving tickets often requires learning new systems and business workflows on the fly.
• Maintain technical documentation, support guides, and troubleshooting procedures.
Qualifications:
• Bachelor's degree in Computer Science, IT, or a related field.
• 2+ years of experience in integration engineering, integration support, or a similar role.
• Hands-on experience with Boomi or another iPaaS platform.
• Strong, demonstrable skills in SQL and database troubleshooting — this role requires day-to-day, hands-on database work.
• Strong REST/SOAP API knowledge, including testing, debugging, and validating API-based integrations.
• Solid experience with structured testing and validation practices for integration issues.
• Good understanding of integration patterns, cloud technologies, and production support.
• Strong analytical, communication, and stakeholder-management skills.
• Ability to work flexibly across engineering, product, and implementation stakeholders, and to quickly learn new systems and domains.
• Willingness and ability to work the required shift: 6:00 PM – 5:00 AM.
Preferred Skills
• Boomi or relevant iPaaS certification.
• Experience with Intapp Integration Builder.
• Knowledge of Azure Functions, Logic Apps, and other Azure services.
• Experience with monitoring, logging, and integration observability.
