A Global SaaS company is expanding its Sydney-based Technical Support function and is seeking an Integration-focused Support Engineer to join the team on a 12-month contract, with a strong view to permanent conversion.
This role sits within the Integrations Support team, working directly with customers to troubleshoot and resolve issues where third-party applications connect into the platform.

  • Investigating problems across SQL queries, Linux systems, logs, and service behaviour.
  • Supporting customers experiencing email and Outlook integration issues (SMTP, O365, Exchange).
  • Reproducing defects, performing root-cause analysis, and escalating complex cases to engineering teams.
  • Managing customer communication throughout the lifecycle of an investigation, ensuring clear and timely updates.
  • Working within ITIL-aligned incident and problem management processes.
What We’re Looking For
  • Experience in Application Support, Technical Support, Platform Support or Integration Support.
  • Strong troubleshooting capability with JavaScript, SQL, and Linux.
  • Familiarity with REST APIs and tools such as Postman.
  • Understanding of authentication protocols (OAuth, SAML, OIDC, SSO).
  • Exposure to email technologies such as SMTP, IMAP, Exchange Online or O365.
  • Excellent communication skills and a calm, customer-focused approach to problem solving.
  • Experience in SaaS or large enterprise environments is highly desirable.
  • ITIL/ITSM exposure beneficial.
