Build and ship React Native apps using Expo for a global finance platform, with emphasis on performance, clean code, and direct impact on the product.
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.
