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 work

Design and own mobile application architecture in React Native, from core foundations to production

Make architecture decisions independently, with a focus on scalability, maintainability, performance, and reliability

Build and maintain backend services in Node.js that support mobile product functionality

Design and work with SQL databases, especially Postgres, with strong attention to data modeling, performance, and maintainability

Define scalable engineering patterns across mobile, backend, and API integration layers

Own application quality standards across architecture, code structure, testing, responsiveness, and developer experience

Define technical direction, not just implementation details

Set and enforce quality standards across both AI-generated and manually written code

Translate ambiguous product needs into clear technical solutions

Ensure the performance, quality, and responsiveness of applications

Collaborate directly with clients to ensure smooth communication and strong understanding of requirements

Contribute to system design, performance strategy, testing strategy, and engineering productivity

Operate in an AI-first workflow without compromising engineering standards

This is a fast-paced environment with real production stakes. You will be expected to move quickly, think at systems level, and make strong technical decisions with minimal hand-holding. If you are comfortable owning mobile architecture, contributing across backend systems, and raising the technical bar in a high-accountability environment, this role is for you.

Candidate requirements

Strong proficiency in React Native, Node.js , and SQL databases, especially Postgres

Proven experience designing, developing, and maintaining production applications

Strong understanding of performance, responsiveness, maintainability, and overall software quality

Ability to communicate clearly with clients and stakeholders

Full-time availability in a remote environment<
