Mobile Developer - Finance Super App (Poland)

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, 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.

The Role

We are looking for mobile developers to build BJAK's finance super app across Android and iOS.

This role is for strong mobile builders who can ship clean, reliable and intuitive mobile experiences, whether their main strength is Android, iOS or both.

What You'll Own

• Build and ship mobile features for Android and/or iOS.
• Create simple mobile flows for insurance, payments, claims, renewals and financial services.
• Work with product, design and backend teams to turn complex journeys into usable mobile products.
• Integrate APIs and handle edge cases, loading states, errors and production issues.
• Improve app performance, reliability, crash rate and user experience.
• Support fast product launches, experiments and iterations across mobile journeys.
• Help set high standards for mobile product quality across the super app.

What We're Looking For

• 3+ years of mobile development experience in Android, iOS or both.
• Strong experience with Kotlin and/or Swift.
• Experience shipping production apps used by real users.
• Strong product sense and attention to mobile UX.
• Able to work with APIs, analytics, crash logs and production feedback.
• Fast, practical and comfortable owning work with limited handholding.
• App links, GitHub, screenshots or examples of shipped work are a strong advantage.

The Kind of Builder We Want

• Thinks like a product builder, not just a mobile coder.
• Cares about smooth flows, small details and real user behaviour.
• Can work across ambiguity and ship without waiting for perfect specs.
• Takes production quality personally.
• Honest about what they built directly versus what the wider team delivered.

This Role Is Not For

• Developers who only want to build isolated screens.
• People who do not care about UX, performance or reliability.
• Candidates who cannot explain their own contribution clearly.
• People who need heavy guidance for every task.
• Engineers who move slowly in a high-growth environment.

Location

This role is remote, but candidates must be based in Poland. We are hiring specifically for this market, so applicants should already be based in Poland.

Language

English is our main working language across global teams. Strong English communication is required.

Interview Process

Our process is designed to move fast:

1. Online assessment or practical task

2. Technical interview

3. CEO / final round

For strong candidates, we aim to complete the process and make an offer within 1 week from the start of the interview process. Candidates who complete assessments quickly will be prioritized.
