Senior React Native & React Engineer LATAM

Lead-level frontend and mobile ownership. AI-first delivery. Architecture decisions. We are looking for a highly senior engineer who can operate at Lead Engineer level across frontend and mobile applications. This is not a role for someone who only executes tickets. We need someone who can make architecture decisions independently, design scalable frontend and mobile systems, and turn ambiguous product needs into production-ready applications. This is a high-ownership role on a lean team. The default mode of execution is AI-first. Engineers use AI agents and tools such as Cursor, Claude, and similar platforms to accelerate research, planning, implementation, testing, and refinement, but ownership stays fully with the engineer. The person in this role must be able to use AI to move fast while maintaining strong judgment around architecture, correctness, performance, usability, maintainability, and overall product quality.
