Senior Frontend AI-First Platform/Systems Engineer (LATAM)

Job description

Lead-level frontend ownership. AI-first delivery. Architecture decisions.

We are looking for a highly senior frontend engineer who can operate at Lead Engineer / Architect level.

This is not a role for someone who only executes tickets. We need someone who can make architecture decisions independently, design frontend systems with long-term scalability in mind, and turn ambiguous product needs into production-ready frontend solutions.

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 frontend quality.

We are specifically looking for candidates who have already held responsibilities similar to Lead Engineer, Staff Engineer, or Architect in previous roles.

The work

• Design and own frontend architecture in React and TypeScript, from shared foundations to production

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

• Build and evolve shared component systems, design systems, and frontend platform foundations across the codebase

• Define scalable frontend patterns that improve consistency, development velocity, and long-term maintainability

• Own frontend quality standards across architecture, code structure, testing, 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

• Contribute to frontend system design, performance strategy, testing strategy, and developer 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 frontend architecture and raising the technical bar in a high-accountability environment, this role is for you.
