About the Company

The original mission of BJAK is we believe people deserve smarter ways to plan, save and grow their money. This is the origin of our name. Started in 2019, we built the first mobile-first, insurance platform, enabling insurance to be accessible online by millions in the region. Today, its the leading insurance platform in Southeast Asia. Today, we are expanding ways to help people in the region — this includes spending, saving, investing, exchanging, travelling, and more. Our mission is help people get more from their money every day. We have teams working around the world, with over 20 nationalities from our offices and remotely, who truly enjoys their work. We are looking for the most talented and driven people we can find. We are looking for people who work for their passion, not counting hours. Who loves building great next-generation products, not status quo. Who cares about redefining how everyone around us can get the best financial applications, not for an exclusive few. If you're this person, we'd love to talk to you.

• Complex API Integration: Orchestrate high-throughput, secure communication layers integrating a massive suite of backend REST and GraphQL microservices with minimal latency.
• Performance & Efficiency: Optimise memory footprints, thread execution, and network rendering to guarantee ultra-efficient, butter-smooth app processing under heavy load.
• AI-Driven Engineering: Extensively utilise Claude Code and modern agentic tools to test, refactor, and build out native features faster.
• DevOps & CI/CD: Maintain automated mobile CI/CD pipelines (Fastlane, GitHub Actions) for seamless, secure Google Play deployments and automated testing suites.

What You Bring

• Large-Scale Mobile Experience: Proven commercial history of designing, building, and scaling large-scale consumer or enterprise Android apps used by millions.
