Senior React Native AI-First Engineer (LATAM)

Lead-level mobile ownership. AI-first delivery. Architecture decisions.We are looking for a highly senior mobile engineer who can operate at Lead Engineer level.This is not a role for someone who only executes tickets. We need someone who can make architecture decisions independently, design mobile systems with long-term scalability in mind, 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 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.The workDesign and own mobile application architecture in React Native, from core foundations to productionMake architecture decisions independently, with a focus on scalability, maintainability, performance, and reliabilityBuild and maintain backend services in Node.js that support mobile product functionalityDesign and work with SQL databases, especially Postgres, with strong attention to data modeling, performance, and maintainabilityDefine scalable engineering patterns across mobile, backend, and API integration layersOwn application quality standards across architecture, code structure, testing, responsiveness, and developer experienceDefine technical direction, not just implementation detailsSet and enforce quality standards across both AI-generated and manually written codeTranslate ambiguous product needs into clear technical solutionsEnsure the performance, quality, and responsiveness of applicationsCollaborate directly with clients to ensure smooth communication and strong understanding of requirementsContribute to system design, performance strategy, testing strategy, and engineering productivityOperate in an AI-first workflow without compromising engineering standardsThis is a fast-paced environment with real production stakes.
