Technical Support Engineer (L2)

We’re looking for a Technical Support Engineer to serve as a front-line technical partner for our customers. In this role, you’ll handle incoming technical issues, perform triage and deep investigation, debug problems across APIs, databases, integrations, and application behavior, and work closely with Engineering when escalation is required.This is a hands-on role for someone who has already worked in technical or product support and enjoys digging into how systems work, not just passing tickets along. You’ll own issues end-to-end, communicate clearly with customers and internal teams, and over time have opportunities to contribute small fixes under engineering practices.

Not sure if you have enough experience to meet the challenge, but still willing to learn and join our team? Send us your application and we will be happy to talk about the possibilities. Think big!
