About BJAK

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, 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 enjoy 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.

About the Job

We are looking for talented iOS Developers to build and evolve our mobile applications that power BJAK's insurance and financial products. You will also contribute to features that leverage automation and AI-assisted capabilities where they improve user experience and operational efficiency.

  • 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 iOS development experience using Swift.
  • Strong experience building and maintaining production iOS applications.
  • Solid understanding of SwiftUI, UIKit, async/await and modern iOS architecture patterns.
  • Strong knowledge of mobile UX, usability, accessibility and user-centered design.
  • Experience integrating REST APIs and troubleshooting production issues.
  • Comfortable working independently in a remote, distributed engineering team.
  • Strong ownership, fast execution and attention to product quality.
  • GitHub, App Store links or examples of shipped applications are highly preferred.

Tech Stack

  • 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

  • Technical Interview: We assess iOS development fundamentals, architecture, API integration, debugging, UX thinking and production-quality engineering.
  • CEO Interview: We assess ownership, execution speed, ambition, judgement, integrity and alignment with BJAK's builder culture.

For a full-time software engineering role, it's crucial that we stay sharp with our coding abilities. Expect technical questions that might involve solving problems on the spot or discussing algorithms. Practise on platforms like LeetCode or HackerRank to get comfortable with the types of questions that often come up.
