About B2Spin

We are B2Spin, and we are dedicated to delivering the best Free-to-Play Social Casino and gaming experiences by creating captivating, engaging, and unique products that are accessible to everyone. We have built a team of talented professionals from all over the globe, who are working to continually improve the experiences of our players. We are not looking to just be part of the industry, but to revolutionize it.

AI-Driven Engineering Culture

We are actively building an AI-driven engineering organization with a clear and deliberate stance: artificial intelligence is a core part of how we build and deliver software — not an experiment, not a trend, and not an optional add-on. AI is embedded into our engineering workflows, from system design and prototyping to refactoring, testing, and code review. We expect engineers to be fully comfortable working in AI-driven environments and to treat AI as a primary productivity multiplier. Strong engineering judgment, architectural ownership, and accountability remain essential—AI amplifies our engineers, it doesn’t replace responsibility for technical decisions.

What you will be doing • Write well-designed, testable, and scalable code that powers our mobile gaming experiences • Lead the full development cycle from sprint planning to release, ensuring seamless collaboration between engineering teams and product owners • Manage and streamline release processes for multiple mobile applications built from shared codebases • Mentor and inspire the engineering team, fostering technical excellence and continuous learning • Implement AI agents and automation tools to optimize code reviews and developer workflows • Proactively manage technical debt and drive long-term architectural vision

What we are looking for • Proven expertise in React Native, TypeScript, TanStack Query, Zustand, React Navigation, and MMKV • Deep understanding of monorepo architectures and building applications from scratch • Strong experience with third-party integrations including external APIs, analytics, and payment gateways • Expertise in creating smooth animations with React Native Reanimated • Hands-on experience with push notifications, deep links, and universal links • Delivery-oriented mindset with exceptional attention to UI/UX detail and strong English communication skills

Would be a plus • Experience in writing Unit tests • Native Development (Java/Kotlin, Objective-C/Swift) • Creativity in solving different complex tasks • Experience in web development, particularly with Next.js • Experience setting up and maintaining mobile CI/CD pipelines (Azure Pipelines, Fastlane)
