About the role

Key responsibilities & impact

Test new features across web, mobile, and API layers in close collaboration with product and engineering during active development.
Write, maintain, and execute test cases and test plans for new and existing features.
Run regression testing cycles ahead of releases and confirm each build meets quality standards before it ships.
Perform exploratory testing to find issues that scripted test cases miss.
Test backend and API behavior, including request/response validation, error handling, and data integrity.
Validate wallet, balance, and financial transaction flows.
Identify, document, and track defects with clear reproduction steps, evidence, and severity assessments, and verify fixes.
Work with the mobile QA engineer and automation engineer to identify regression cases worth automating and contribute to automated test coverage as time allows.
Flag quality risks, gaps in coverage, and process improvements to the QA Lead.
Report to the QA Lead and partner with mobile QA, automation engineering, product, and engineering.

Requirements

What you’ll need

3 to 5 years of hands-on QA experience on web and/or mobile software products.
Strong manual testing skills: 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.
Interest in betting and prediction markets (markets, odds, events, settlements). Direct sportsbook or betting experience is a strong plus.
Comfort using AI tools (e.g., ChatGPT, Copilot, Claude) to speed up test design and bug triage.
Clear written communication, and the ability to prioritize when several teams need testing at once.
Comfortable in a fast-moving Agile environment with regular releases, and working remotely with a day that overlaps ET or CT business hours.
