Job description

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 Android Developer to build the native Android experience for BJAK's AI Finance Agent

This role is for someone who cares about clean user flows, fast performance, product quality and shipping reliable mobile features used by real customers.

What Will You Build

• Build and ship native Android features for onboarding, accounts, cards, payments, transfers, rewards and AI-assisted user journeys.

• Turn complex financial flows into simple, fast and reliable mobile experiences.

• Work closely with product, design, backend and AI engineers to take features from idea to production.

• Own app quality across performance, crash rate, loading states, edge cases and release stability.

• Use production feedback, analytics and customer behaviour to improve what you build after launch.

• Integrate APIs, authentication, secure data handling and financial workflows with strong attention to reliability.

What We're Looking For

• Strong native Android experience using Kotlin.

• Experience shipping Android apps used by real users.

• Good understanding of Android architecture, Jetpack, Coroutines, Flow and modern Android development.

• Strong product sense and care for UX, not just screens and tickets.

• Able to debug production issues and improve performance, reliability and app quality.

• Comfortable working with ambiguity and moving fast without lowering the bar.

The Bar

We are looking for engineers with real technology career highlights. A strong highlight is not just working at a famous company. A strong highlight means you personally helped build, ship or scale a serious product, platform or system.

This Role Is Not For

• Engineers who only want fully defined tickets.

• Developers who build screens without caring about user experience.

• People who ignore crashes, edge cases, loading states or performance.

• Engineers who move slowly in a startup environment.

• People who exaggerate impact without explaining their actual contribution.

Location

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

Language

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

Interview Process

Our process is designed to move fast:

• Online assessment or practical task
• Role-specific interview
• 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.
