About Toptal:

Toptal is the world’s leading premium talent marketplace, trusted by 30,000+ clients, processing over $5B in payments across 140+ countries.

We’re building a borderless finance platform on stablecoin rails, focused on fast, reliable money movement at global scale. This team is shipping the first production version of the product — quickly, iteratively, and with high quality.

Get ready to:

Work in a small team shipping mobile features continuously.

Take ownership of React Native implementation from ticket to production.

Collaborate closely with backend engineers to deliver end-to-end user flows.

Ship fast, fix fast, and improve based on real usage.

What you’ll do:

Build and ship React Native apps using Expo for iOS and Android.

Implement core user flows: onboarding, authentication, payments, balances, and settings.

Integrate backend APIs efficiently and handle loading, error, and retry states correctly.

Focus on performance and reliability under real-world conditions (poor connectivity, retries, edge cases).

Own releases: builds, OTA updates, store submissions, and production fixes.

Keep the codebase clean, maintainable, and easy to extend as the product evolves.

What we’re looking for:

4+ years building production mobile apps, with strong React Native experience.

Hands-on experience with Expo (managed or bare), including builds and releases.

Strong TypeScript skills and comfort working with API-driven products.

Solid understanding of mobile app performance, navigation, and lifecycle.

Experience shipping frequently in fast-moving product teams.

Fintech or payments experience is a plus, but execution matters more than domain.

How you work (values we expect):

Execution-first - you ship working software, not just ideas.

Ownership - you see features through from implementation to production.

Product-aware - you understand how users interact with what you build.

Speed with discipline - you move fast without breaking trust.

AI-assisted - you use tools like Cursor/Claude Code/etc. to move faster.

Bonus points if you have…

Shipped fintech, payments, or crypto-related mobile apps.

Experience with mobile security (secure storage, biometrics).

Built flows involving KYC, document capture, or real-time balances.

Worked on early-stage products where speed mattered.

What we offer:

Clear ownership and real responsibility from day one.

Fast execution with minimal process overhead.

Direct impact on a global financial product.

A senior team that values shipping, quality, and learning.
