Senior Full-Stack Developer (React / Node.js) AI-First

COMMIT · AM, BR

We are looking for Senior Full\-Stack Developer (React / Node.js) AI\-First. You will own features end\-to\-end: React on the front\-end, Node.js on the back\-end, deployed with Docker and Kubernetes on AWS. Small team, hands\-on senior role — you ship, you deploy, you support what you build. The team develops AI\-first. AI coding tools are the default way work gets done, not an experiment. On the front\-end in particular, we expect you to generate most of the UI with AI — screens, components, state, tests — and spend your time on architecture, review and product quality, not on hand\-typing JSX. We expect you to already work this way. **What you will do:** * Build and ship full\-stack features: React front\-end \+ Node.js services and APIs * Build the front\-end AI\-first: turn designs, specs or screenshots into working React screens using AI coding agents; generate components, forms, tables, state logic and tests; then review, harden and integrate * Set up and maintain the AI workflow for front\-end work: project rules/context files, component conventions, design\-system references and prompt patterns so AI output matches the codebase * Containerize services with Docker, deploy and operate them on Kubernetes and AWS * Maintain CI/CD, monitoring and logging for what you own * Review code (human\- and AI\-written) and work directly with the product and management team Requirements: **Must have:** * 5\+ years of professional software development * True full\-stack: 3\+ years where you regularly delivered both the React front\-end and the Node.js back\-end of the same features yourself, in production. This role requires equal depth on both sides; profiles weighted to one side only will not fit. * Strong React: hooks, state management, performance, TypeScript * Strong Node.js: API design, async patterns, auth, testing * Hands\-on production experience with Kubernetes, Docker and AWS * AI\-first front\-end development, proven in production: * Daily use of AI coding agents (Cursor, Claude Code, Copilot or similar) to build React UI end\-to\-end * Can show real examples of screens or features built mostly with AI and explain what was kept, what was rewritten and why * Knows how to give the agent the right context (design files, component library, existing patterns, API contracts) to get code that fits the codebase, not generic output * Knows where AI breaks on front\-end work — state bugs, accessibility, performance, inconsistent styling — and how to catch it * AI\-first across the stack: uses AI for back\-end code, tests, refactoring, debugging and reviews as well; can explain how prompts, context and agent workflows are structured, and how output is verified * Git, CI/CD, automated testing as a habit * **Independent, communicates clearly, owns a feature from idea to production** **Huge bonus:** * **React Native** — shipped mobile apps to App Store / Google Play (OTOFusion has a React Native mobile app) * Experience with AI design\-to\-code tools (Figma\-to\-code, v0, Lovable, Bolt or similar) as part of a real delivery flow
