Senior QA Engineer

Що робити

Build and own the automated regression suite in Playwright, covering the funnels that carry the most spend first rather than chasing coverage percentages.
Set up synthetic monitoring against live funnels: a scripted user walks the flow on a schedule, and a failed step pages someone instead of waiting to be noticed.
Wire the suite into CI so it gates every landing and product release, and keep it fast enough that nobody is tempted to skip it.
Own API-level testing of the tracker, the postback endpoints and the Conversion API integrations, where a browser test cannot reach.
Take mobile: store builds, deeplink behaviour after install, and attribution through the mobile measurement partner, confirming an install and a subscription land on the right campaign.

4 or more years in QA, with at least 2 spent building and maintaining an automated suite that other people relied on.
Strong automation practice in Playwright, Cypress or Selenium, with JavaScript or TypeScript at a level where you write the framework rather than only the tests.
API testing experience: request construction, authentication, response validation, and testing integrations you do not control.
CI experience: you have put a suite into a pipeline and dealt with what happens when it starts blocking releases.
The judgment to decide what should be automated and what should not. Automating a rarely changing flow while a payment step stays manual is the mistake we are trying to avoid.

Mobile testing and experience with an MMP such as AppsFlyer, Adjust or Branch.
Experience with subscription or recurring billing products.
Familiarity with trackers, conversion postbacks and server-side event delivery.
SQL beyond the basics, enough to validate data rather than only read it.
Load or performance testing, particularly on landing pages under traffic spikes.
