About the Product:

We support a multi-brand social gaming platform that provides real-time entertainment across web and mobile channels. The product combines a dynamic front-end, RESTful APIs, WebSocket services for live game sessions, and a complex back-end built to handle high user concurrency and large transaction volumes.

The platform is actively evolving, with weekly or bi-weekly releases that include new features, bug fixes, UI improvements, and third-party integrations — all without downtime. Since production issues can directly impact user engagement and revenue, quality, stability, and reliable test automation are essential.

The combination of scale, frequent releases, and real-time functionality creates a challenging technical environment where strong automation practices make a direct business impact.
 

About the Role:

As a QA Automation Lead, you will build the automation function from scratch and take ownership of the overall automation strategy, framework architecture, CI/CD integration, and team growth.

• Lead and mentor QA engineers through code reviews, technical guidance, and daily support.
• Define testing standards, automation processes, documentation, and best practices.
• Own test coverage for assigned product areas and identify gaps before they reach production.
• Collaborate with developers and product managers to analyze requirements and create test plans.
• Manage defect triage, investigate test failures, coordinate fixes, and verify resolutions.
• Improve test reliability, execution speed, and maintainability.
• Identify quality risks and communicate them clearly to engineering and product stakeholders.
• Explore and introduce AI-assisted testing tools and modern automation approaches.
• Support recruitment and onboarding of new automation engineers as the team grows.
   

Required Skills and Experience:

• 5+ years of hands-on QA automation experience, including ownership of an automation codebase.
• Strong experience with Playwright and TypeScript in production-level automation frameworks.
• Solid JavaScript/TypeScript skills for building and maintaining automated tests.
• Experience with Cypress or Selenium may be considered if the overall automation background is strong.
• Proven experience integrating automated tests into CI/CD pipelines, such as GitHub Actions, Jenkins, or similar.
• Strong API testing experience with tools such as Postman, Supertest, or similar.
• Experience testing RESTful APIs; WebSocket testing experience is a strong advantage.
