The Role

We are looking for Mobile developer to build the native Android experience for BJAKs AI Finance Agent.

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 Will You Build

• Build mobile features across Android, iOS or cross-platform flows depending on your strength.

• Create clean journeys for onboarding, accounts, payments, cards, transfers, rewards, travel, FX and AI-assisted features.

• Work from product problem to shipped mobile experience, not just assigned screens.

• Collaborate with backend, design, product and AI teams to launch reliable customer-facing features.

• Improve app quality through production feedback, analytics, crash reports and user behaviour.

• Help raise the standard for mobile UX, reliability and speed across the product.

What Were Looking For

• Strong mobile development experience in Android, iOS or both.

• Experience shipping production mobile apps used by real users.

• Good product sense, UX judgement and attention to edge cases.

• Able to work across APIs, releases, debugging and production issues.

• Hands-on builder who can take ownership without heavy guidance.

• Clear evidence of shipped work: app links, GitHub, screenshots or project explanations.

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 Vietnam. We are hiring specifically for this market, so applicants should already be based in Vietnam.

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. Role-specific 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.
