Platform QA Chapter Lead (all genders) at JustPlay GmbH

Job Description

As Platform QA Chapter Lead on the Platform side at JustPlay, you’ll lead and scale quality assurance for our core app experience — the foundation that powers our games, live operations, and player rewards. Working closely with Engineering, you’ll ensure the platform runs seamlessly across devices, regions, and releases, setting the standard for quality, reliability, and user experience.

You'll split your time between hands-on QA work and leading the QA engineers in the QA chapter: helping them grow in their craft, spreading good practice, and raising the bar for quality across the teams you work with. A key part of this role will be driving smarter, more scalable testing approaches, including AI-driven testing and automation.

Job Responsibilities

• 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.

• Use contract testing (e.g., Pact) to validate backend and service integrations.

• Apply performance and reliability testing across mobile platforms to ensure smooth user experiences.

Job Requirements

• 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.

• Familiarity with project and documentation tools such as Jira and Notion.

Nice to have

• Experience in backend integration testing and API monitoring.

• Experience with contract testing frameworks such as Pact.

Job Benefits

• Work-Life Balance and Flexibility: Flexible working hours and options for digital nomads, occasional office visitors, or regular office-goers

• Mental Health Support: Free personal coaching through our partner nilo.health to support our team members to live fulfilled lives at home and at work

• Training & Development: A competitive personal development budget of up to 2000€/year for training, conferences, workshops, etc. and free language tutoring in German and English with Preply

• Germany-Based Benefits: 25 vacation days, free Wellhub gold subscription, free monthly Deutschland-Ticket, and a monthly €50 tax-free internet contribution

• State-of-the-Art Equipment: Doesn’t matter if you are a MacBook or Windows user; we will provide you with the technical gear you need to succeed

• A Relocation Package: Includes visa support for those who need it

• Engaging and Diverse Work Environment: Join a diverse team, with over 30 nationalities working from over 25 different locations

• Berlin Office Perks: Ergonomic setup, free daily lunch, and a dog-friendly environment.

Benefits may vary depending on location and contract type. Do not hesitate to ask us about more details on our benefits offer.
