About BJAK

The original mission of BJAK is that 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, it's 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 to 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 the 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.

About the Job

We are looking for talented Mobile Developers to build and evolve our mobile applications that power BJAK's insurance and financial products. You will help create intuitive, high-performance native mobile experiences while contributing to AI-assisted features that improve user experience and operational efficiency.

This is a hybrid position where you will be part of a global engineering team working across multiple countries to build reliable, scalable mobile systems.

What You'll Own

• Build and ship high-quality mobile applications for iOS or Android.

• Develop intuitive mobile experiences across insurance, payments, claims, renewals and financial services.

• Work closely with product managers, designers and backend engineers to simplify complex user journeys.

• Integrate backend APIs and ensure mobile applications remain stable, scalable and reliable.

• Continuously improve application performance, crash rates, loading speed, responsiveness, memory usage and battery efficiency.

• Use analytics, production insights and user feedback to continuously improve product quality.

• Build AI-assisted mobile experiences where they create meaningful value for users.

• Contribute to engineering standards, code reviews and continuous improvement across the mobile platform.

What We're Looking For

• 3+ years of professional mobile development experience.

• Strong experience building and maintaining production mobile applications on iOS (Swift) or Android (Kotlin).

• Solid understanding of modern mobile architecture patterns and native platform best practices.

• Experience with SwiftUI/UIKit or Jetpack Compose/Android SDK.

• Strong knowledge of mobile UX, usability, accessibility and user-centered design.

• Experience integrating REST APIs and troubleshooting production issues.

• Strong ownership, fast execution and attention to product quality.

• GitHub, App Store, Google Play links or examples of shipped applications are highly preferred.

Tech Stack

• Swift / Kotlin

• SwiftUI / Jetpack Compose

• Swift Package Manager (SPM) / Android SDK

• SQL / NoSQL

• TensorFlow Lite (on-device inference)

The Kind of Builder We Want

• Thinks about complete user journeys, not just individual features.

• Enjoys turning complex financial workflows into simple mobile experiences.

• Writes clean, maintainable code while moving quickly.

• Comfortable working in an environment with evolving priorities.

• Proactively identifies UX, performance and reliability improvements.

• Takes ownership from idea through production.

• Honest about personal contributions, technical decisions and measurable impact.

This Role Is Not For

• Developers who require fully specified tasks before taking action.

• People who focus only on implementation without considering user experience.

• People who overlook quality, performance, crashes or edge cases.

• Developers who struggle in fast-moving startup environments.

• Candidates who overstate their ownership or impact.

Success Looks Like

• High-quality mobile features are delivered consistently and efficiently.

• Mobile experiences become faster, simpler and more intuitive.

• Users complete financial journeys with minimal friction.

• Performance, stability and reliability improve with every release.

• BJAK continues building world-class AI-powered mobile products used by millions across Southeast Asia.

Interview Process

The process consists of three stages:

1. Online Coding Assessment

   We assess coding fundamentals, problem-solving ability and code quality.

2. Technical Interview

   We assess native mobile development fundamentals, architecture, API integration, debugging, UX thinking and production-quality engineering. The interview will focus on your primary platform (iOS or Android).

3. CEO Interview

   We assess ownership, execution speed, ambition, judgement, integrity and alignment with BJAK's builder culture.

Please share links to your App Store applications, Google Play applications, GitHub repositories, portfolio or examples of shipped work where possible. We value real-world engineering experience, clear ownership and honest thinking more than a formal cover letter.
