Platform QA Chapter Lead

As Platform QA Chapter Lead, you'll lead and scale quality assurance for JustPlay's core app experience — the foundation that powers games, live operations, and player rewards. You'll split your time between hands-on QA work and leading QA engineers: helping them grow, spreading best practice, and raising quality standards across teams.

What you'll do

• Own the full QA lifecycle for JustPlay's app and platform features — from test planning and execution to reporting and defect management.
• Foster a strong quality culture across teams by embedding QA best practices early and tying quality goals to product velocity and platform reliability.
• Drive innovation through AI-driven testing and predictive approaches to identify risks earlier, improve coverage, and reduce manual effort.
• Partner with development, design, and product teams to integrate QA best practices early in the release cycle.
• Design and maintain comprehensive test plans and automated suites for key user flows (login, payments, live events, notifications, etc.).
• Lead, mentor, and scale the QA team — setting up clear processes, code quality standards, and testing frameworks.
• Implement automation and regression testing strategies using tools such as Maestro, Espresso, XCTest, Appium, or similar frameworks.
• Apply performance and reliability testing across mobile platforms to ensure smooth user experiences.

What you'll need

• 5+ years of experience in QA for mobile apps or platforms, including at least 2 years leading teams.
• Proven ability to design scalable QA processes in fast-paced, development-heavy environments.
• Strong experience with automation frameworks, regression testing, and CI/CD pipelines.
• Hands-on experience with mobile debugging tools (Android Studio, Xcode) and network analysis tools like Charles.
• Strong understanding of how to build a quality-first mindset across engineering and product teams.
• Interest in or experience with AI-assisted testing and new QA technologies.
• Strong attention to detail, analytical thinking, and a user-first mindset.
