About The Position

The Quality Assurance Engineer is a generalist responsible for supporting quality across the platform. The role validates new features, runs regression cycles, tests APIs and backend behavior, and helps determine when releases are ready to ship. The engineer provides coverage where needed across web, mobile, and API testing, and works on both feature testing and release cycles. The position reports to the QA Lead and partners closely with the mobile QA and automation engineers and with product. Candidates based in the Eastern or Central time zones are preferred to provide overlap with the engineering team.

Requirements

3 to 5 years of hands-on QA experience on web and/or mobile software products.
Strong manual testing skills, including writing clear test cases and test plans, running regression suites, and exploratory testing.
Experience testing APIs with Postman or similar tools, and working knowledge of SQL for validating data.
Experience with Jira and a test management tool such as TestRail.
Experience testing financial, payments, or wallet flows, or other products where errors have real monetary impact.
Clear written communication and the ability to prioritize when several teams need testing at once.
Comfort working in a fast-moving Agile environment with regular releases and remotely with a day that overlaps Eastern or Central time business hours.
Comfort using AI tools such as ChatGPT, Copilot, or Claude to speed up test design and bug triage.
