About Común

Comun’s mission is to help Hispanic immigrants turn their hard work into upward mobility — starting with financial services that support their transition from a cash-based system to the digital economy.

We offer checking accounts that can be opened using 100+ types of Latin American IDs, access to over 90K locations nationwide to deposit cash, international transfers to 17 countries at market-leading rates, and 24/7 bilingual customer support with <5 min SLA across email, chat, and phone.

We currently process over $1.5B in annual transaction volume and surpassed $100M in annualized international transfers just six months after launch. Comun has raised +$50M from top investors including Redpoint, Costanoa Ventures, and South Park Commons. Our team brings experience from leading fintech companies like Brex, Nubank, and Mercury.

We believe immigrants are the ultimate entrepreneurs — driven by relentless ambition and a vision for a better future for their families. Comun exists to serve them throughout their journey.

About the Role
Own the mobile experience for a fintech app serving an underserved community. You'll shape the product roadmap, translate design into production code, and keep our component library sharp so we can ship fast without breaking things. Our stack is React Native, Expo, TypeScript, and GraphQL — built on trunk-based development with fast iteration cycles.

What You'll Do

Build and ship features across payments, banking, KYC, and authentication flows, working directly with product, design, and backend teams.
Define and enforce frontend patterns, tooling, and processes that raise the quality bar and speed delivery.
Own observability and testing for core mobile flows — you'll be the person who catches regressions before users do.
Evolve our design system and component library for consistency at scale.
Partner with leadership on architecture decisions and technical roadmap.

You Are

Comfortable owning technical decisions end-to-end in a fast-moving startup where the right answer isn't always obvious.
Experienced debugging hard problems across mobile, API, and native layers.
Fluent in trade-offs — you can explain why something is the right call, not just that it works.

Requirements

Strong React Native and TypeScript production experience — you've written components other people depend on.
Experience shipping and maintaining iOS and Android apps through the App Store and Google Play.
Deep understanding of frontend architecture, state management, testing, and mobile performance.
Experience with GraphQL in a production codebase.
Proven track record in fintech, financial services, or a similarly regulated, high-uptime environment.
Comfortable with secrets management, CI/CD pipelines, and working in a codebase with pre-commit hooks and automated code review.

Nice to Have

Experience with KYC, remittances, or payment flows.
Familiarity with Expo's managed vs. bare workflow trade-offs.
Prior work on observability tooling (Datadog or similar) for mobile.

Team

We are a team of 40 based out of New York, coming from industry-leading companies like Brex, Nubank, Cruise, and Verkada. Over half of us are immigrants, and have experienced the problems we’re solving first hand. We value customer focus, high ambition, principled decision-making, and deep trust.
