·         Strong troubleshooting experience across enterprise applications, APIs, data, configurations, and system integrations.

Roles and Responsibilities

In this role, you will test the product through the user’s lens by conducting user-centered quality assurance testing across new and existing functionality using real-world workflows. You will serve as the first line of technical investigation for escalated Tier 2 and Tier 3 support requests, reviewing application and integration logs to diagnose whether issues stem from configuration, user workflow, data, integrations, or product defects. When direct resolution is not possible, you will deliver complete defect documentation to Engineering—including reproduction steps, logs, and business impact—and translate user feedback into structured user stories, technical requirements, and feature requests. Additionally, you will partner with Product and Engineering to clarify scope, coordinate user acceptance testing in staging environments prior to release, monitor post-deployment performance, support release planning, and build trusted, solutions-oriented relationships with users and clients.

·         Experience investigating and resolving complex data-related questions across integrated applications and systems.
