Senior Frontend Engineer – Remote (Brazil)

What You’ll Do & How You’ll Make Your Mark

• Architect and build high-performance, production-grade UI in React, Redux (or similar state management), and TypeScript
• Use AI across the delivery lifecycle, not just code generation, and set the guardrails the team works inside: how generated code gets reviewed, how provenance and licensing are checked, and what customer data may enter a prompt
• Design and build front-end interfaces that integrate AI-powered features, such as chat, content generation, and smart recommendations
• Own the performance, scalability, and reliability of high-traffic, customer-facing applications, from bundle size to render performance
• Partner closely with product, design, and backend engineers to take features from concept to production quickly, without sacrificing quality
• Set and enforce frontend engineering standards: component reuse, design-system consistency, testing coverage, and code review rigor across both squads
• Mentor mid-level and junior engineers on architecture decisions, debugging technique, and modern React patterns
• Drive continuous delivery practices, shipping iteratively against real user feedback instead of large, infrequent releases
