About the role

As a Technical Support Engineer, you are the technical backbone of our customer support organization. You independently own complex issues across application, integration, and infrastructure layers, from first contact through root cause and resolution. You're the critical bridge between frontline support and engineering, trusted by customers and colleagues alike to diagnose fast, communicate clearly, and close cases right. This is not a script-following role. You'll work with real enterprise environments, live production data, and customers who depend on your expertise every day.

- Diagnose OS-level and setting failures, coordinate with infrastructure and security teams as needed

- Manage the full case lifecycle with clear customer communication, timely updates, and root cause documentation





- Serve as escalation point for Tier 1 and collaborate with Tier 3 and Engineering on complex issues

- Mentor junior team members, contribute to the knowledge base, and participate in on-call rotations
