• Identify systemic product risks that cannot be detected within a single engineering domain;
• Require teams to improve builds, test results, documentation, or other quality artifacts when they do not meet agreed standards;
• Lead the transition from predominantly manual testing toward a balanced Quality Engineering model;
• Build sustainable E2E and regression automation for critical product scenarios;
• Introduce quality gates into CI/CD pipelines;
• Improve test environments, test data, reporting, and automation stability;
• Introduce risk-based testing, shift-left practices, and appropriate AI-assisted QA tools;
• Reduce regression time and release uncertainty without sacrificing product quality;
• Build and lead the Product Quality team responsible for product acceptance, critical regression, E2E testing, user-experience validation, and E2E and regression automation;
• Hire, develop, and mentor manual QA, automation, and SDET engineers;
• Assess existing QA engineers and define appropriate development paths based on skills, motivation, and demonstrated results;
• Establish clear ownership, expectations, and measurable outcomes for every team member;
• Coordinate the quality function across Backend QA, Client QA, and other QA;
• Work with engineering leaders to ensure that component-level testing is completed before Product Quality acceptance;
• Establish common quality standards, metrics, and audit practices across QA teams;
• Conduct regular quality reviews and identify gaps in domain-level testing;
• Ensure that standards reflect the needs of all QA directions rather than one specific platform or domain;
• Act as the technical owner of QA standards or appoint and support an appropriate Quality Engineering Technical Lead;
• Define and monitor meaningful quality indicators, including escaped defects, critical regression coverage, automation stability and flaky-test rate, regression duration, release-blocking defects, defects at system boundaries, and production and support trends;
• Use analytics, support cases, incidents, and production signals to identify areas requiring additional coverage;
• Present product-quality risks and improvement progress to engineering and product leadership;
• Establish the Product Quality function and its responsibilities;
• Define the interaction between Backend QA, Client QA, and Product Quality;
• Introduce transparent product-acceptance criteria;
• Identify critical E2E and regression scenarios;
• Create a prioritized automation roadmap;
• Launch measurable improvements to automation, CI quality gates, and regression speed;
• Provide leadership with a transparent view of product readiness and quality risks.

• 5+ Years of experience in QA or Quality Engineering;
• 3+ Years in a QA leadership or Quality Engineering leadership role;
• Strong product mindset with the ability to identify user, business, and systemic risks, not just verify compliance with documented requirements;
• Proven experience transforming manual testing into an engineering-driven quality function;
• Experience building or significantly improving E2E and regression automation;
• Strong understanding of test automation architecture, CI/CD integration, test environments, and quality gates;
• Ability to review automation approaches, framework architecture, code quality, and engineering practices;
• Experience testing high-scale mobile applications or games;
• Strong knowledge of mobile application testing, backend and API testing, distributed and cross-system scenarios, analytics validation including Firebase, databases and SQL-based platforms, advertising and attribution systems such as Adjust or AppsFlyer, and release and production quality management;
• Experience working with Android Studio, Xcode, Charles Proxy or similar tools, API clients, and mobile automation frameworks;
• Strong leadership skills and the ability to influence teams in a matrix structure;
• Ability to make difficult quality decisions and clearly explain product risks;
• Fluent Russian;
• English at Intermediate level or higher;
• Nice to have: experience with ad-driven mobile products, testing monetization, consent, GDPR/CCPA, payments, or analytics, building SDET or automation teams, applying AI tools to testing, test design, defect analysis, or QA operations, working with incident, support, and production data.

• Competitive salary and benefits package;
• Flexible working hours;
• Remote/office work options;
• Career growth and professional development opportunities;
• Opportunity to work with a talented and passionate team in a creative and dynamic environment;
