Senior Frontend Engineer (React Native)

Lendable is on a mission to build the world's best technology to help people get credit and save money. We're building one of the world’s leading fintech companies and are off to a strong start:

We’re looking for a Senior React Native Engineer to join the Lenda team - our new brand in Mexico - building a new consumer credit card as part of our continued international growth.

Having recently launched in closed beta, we’re iterating quickly and refining the product as we prepare for a full public launch and continued growth in Mexico.

Your primary focus will be our React Native mobile application, delivering high-quality features and evolving a clean, scalable frontend codebase. You’ll collaborate closely with backend engineers to agree API behaviours through clear, documented contracts, contribute across the broader frontend surface area where needed, and partner with product stakeholders to deliver well-defined, high-impact improvements.
