QA Automation (JavaScript) Engineer

Powered by advanced AI, first-party data and world-class engineers, we’ve perfected the offerwall experience for monetizing and scaling app publishers with solutions like Playtime and Arcade – now the fastest growing rewarded advertising channel globally – driving incremental engagement, retention, and revenue. We are looking for a Mid-Level QA Automation Engineer to join our UI-heavy Catalog team who takes personal ownership of product quality, ensuring that every solution we deliver is stable, performant, and backed by clear documentation. Full-Stack Automation: Develop and maintain end-to-end test suites using Playwright (TypeScript) that cover both complex UI interactions and the underlying API logic.

API Rigor: Design and execute sophisticated API tests (integration and contract testing) to validate request/response payloads, status codes, and data consistency across our microservices.

Utilize AI tools to speed up test script authoring, generate synthetic test data, and implement self-healing UI tests.

Ensure the Offerwall renders perfectly in various web-views and mobile browsers, using visual regression tools to catch UI regressions.

Verify that frontend actions correctly reflect in our datastores (DynamoDB, Redis, MySQL) by querying databases directly within your test scripts.

Own the quality gate in our pipeline, ensuring that both UI and API tests provide fast, reliable feedback to the engineering team

You have 3+ years of experience in QA Automation, with professional-grade proficiency in Playwright and TypeScript/JavaScript.
