Middle QA Engineer for Client Centric Team
About the role
Why this role exists:
This role exists to make sure our products work reliably across Web, native Mobile, Backend, and integrations. You’ll own quality from feature understanding and test coverage to defect investigation and release support, helping teams ship with confidence.
What you’ll drive:
Test strategy & coverage
Analyze requirements and product changes, identify gaps and risks, and define the right test coverage.
Design and execute functional, regression, integration, exploratory, and end-to-end testing.
Validate functionality across UI, API, database, and integration layers.
Assess regression and release risks and make quality visible before changes go live.
Investigation & debugging
Investigate defects and localize issues across client, backend, data, integrations, and environments.
Use browser DevTools, network debugging, proxy tools, API tools, logs, and databases to get to the root cause.
Inspect HTTP/HTTPS requests and responses to troubleshoot Web and Mobile issues.
Verify bug fixes and make sure changes don’t introduce new problems.
Web, Mobile & Backend QA
Test Web applications across relevant user flows, integrations, and edge cases.
Test native iOS and Android applications and investigate issues using platform-specific debugging tools.
Test REST APIs and Backend functionality, including authentication, authorization, and API communication.
Validate data using SQL queries and relational databases.
Work with API tools such as Postman, Swagger, or similar.
Releases & cross-team collaboration
Support software releases and contribute to release readiness decisions.
Communicate testing progress, blockers, risks, and quality clearly to the team.
Work with developers and other stakeholders to investigate issues and unblock delivery.
Contribute to improving QA processes, documentation, and testing approaches.
QA Pool adaptability
Quickly understand new products, technical areas, and testing contexts.
Bring a generalist QA mindset and apply the right testing approach rather than relying on one fixed process.
Work independently while knowing when to ask questions, challenge assumptions, or raise a risk.

Ability to investigate issues across UI, API, database, and integration layers.
Hands-on experience with Git and common development/release workflows, including branches, merges, pull requests, tags/releases, and basic conflict resolution.
Experience supporting software releases and understanding of functional, regression, integration, exploratory, and end-to-end testing.
Ability to work with incomplete requirements, ask the right questions, identify risks, and build sufficient test coverage.
Intermediate English or higher, with fluency in Ukrainian or Russian.
Nice-to-have
