At Endex, you will help customers get answers fast by taking ownership of technical investigations across support requests. This onsite role in Denver, CO supports a team that partners closely with engineering to resolve product and integration problems, reduce repeat incidents, and turn recurring issues into clearer runbooks and better diagnostics.

What you’ll do

Diagnose production issues by using logs, request traces, API responses, and reproducible examples to isolate failures across the product and its integrations.
Drive technical resolution through workaround validation, coordination with engineering on fixes, and confirmation that the customer’s workflow is working again.
Resolve what you can using supported fixes, then validate outcomes with the customer team.
Support incident response by providing technical context and timely investigation updates.
Prevent repeated incidents by writing runbooks and root-cause summaries, improving diagnostic tooling, and bringing recurring defects back to product engineering.

What you bring

Debugging ability to reason through logs, API behavior, and system dependencies.
Coding fundamentals to read code and build small tools or reproductions when needed.
Clear documentation that leaves investigation notes another engineer can pick up.
