About this Manual QA Engineer role at Vacancies
About your role: We are looking for a Manual QA Engineer. You'll own the quality of our high-load web products and directly affect product stability, monetization and release speed. The role covers APIs, databases, analytics events, payment flows and A/B experiments across multiple brands and platforms. You'll also be part of an AI-first QA process, using AI tools and agents for test design, test runs and bug investigation, and helping the team improve these workflows.
In this role, you will
Perform functional testing of new web features and verify bug fixes (UI, user flows, cross-browser, responsive)
Run smoke, sanity and regression testing before releases; perform post-release checks on production
Test analytics and CAPI events: parameters, deduplication, data validation (DevTools, BigQuery)
Run API checks and prepare test data (Postman, MongoDB)
Test business logic, A/B experiments and monetization flows (admin panel, feature flags)
Review requirements, plan testing and assess risks
Maintain test documentation (Qase, Jira)
Investigate bugs via console, network and service logs (Lens): client vs backend, root cause
Work within SCRUM and SDLC, improving testing speed and quality (incl. AI tools)
It's all about you
2-3 years of manual QA experience with web applications: UI, API, Web Push, Email
DevTools: Network (payload, status codes), Console, Application (cookies, Storage, service workers)
HTTP / REST: methods, status codes, headers, cookies; requests in Postman / curl
MongoDB (find, aggregate) and BigQuery (SQL): you write queries and prepare test data independently
CAPI conversions: verification of server-side events (parameters, event_id, deduplication with pixel) via Events Manager / test events
Test design, SDLC / STLC, TMS (Qase), Jira / Confluence
Use of AI tools in your work (Claude Code)
Experience with logs
Git and IDE (VS Code): clone, switching branches, pull; reviewing changes in MR / diff; running the project locally
Ability to verify AI output instead of taking it on faith
English Intermediate (B1)
Would be a plus
A/B testing: group distribution, feature flags
Web Payments: payment providers, test cards, 3DS, recurring, refund
Basic UI / API automation: JS/TS, Playwright, Postman tests
