The ideal candidate brings a strong quality mindset to SaaS and enterprise environments, with the ability to comprehend how configurations, transactional processes, integrations, and downstream data flows interact within a broader ecosystem. Responsibilities include independently translating complex requirements into structured test strategies, executing detailed functional testing via web-based interfaces, and validating integration points and data-parity results. The role requires strong analytical judgment, attention to detail, disciplined documentation practices, and effective collaboration with platform administrators, business stakeholders, and technical teams. This is a temporary 6-month opportunity requiring consistent overlap with Pacific Time business hours.
