Design System & Component Library (Cross-Application): Establish and own a standardized, versioned component library that implements the design system published by our UX team. Establish Storybook as the published, single source of truth for the component library. Drive adoption across multiple product and engineering teams so components, patterns, and design tokens are reused everywhere instead of re-built per team. Cross-Team Collaboration: Work closely with product managers, designers, back-end engineers, and other teams contributing to the AI portal evolution. Define clean front-end contracts and component boundaries across multiple contributors and time zones. UI/UX, Accessibility & Performance: Implement best practices in UI/UX, accessibility (WCAG), and performance optimization. Own front-end performance metrics for the surfaces you ship. Modern Web Capabilities: Apply modern front-end technologies (React, Next.js, TypeScript) to deliver experiences that feel fast, responsive, and reliable. API & Microservices Integration: Integrate front-end applications with the Bruin SDK, public APIs, and back-end microservices. Partner with the Integration Engineer on the developer experience surfaces. AI-Augmented Engineering: Use AI-assisted engineering tools as a primary part of your workflow - directing them to generate, refactor, and validate code while applying judgment to review output and make design and architectural decisions.

Proficiency with Storybook (or an equivalent component workshop) for component development, documentation, and testing. Solid background in agile methodologies and DevOps practices. Excellent communication skills and ability to work effectively with distributed, cross-functional teams. NICE TO HAVE: Experience publishing a design system as canonical, AI-consumable context that AI dev tools and agents can reference (e.g., Chromatic for publishing, MCP-based tooling). Front-end work on AI-powered applications — chat interfaces, agentic UIs, streaming responses, or tool-use surfaces. Background in enterprise software, telecommunications, or B2B tech. Experience building developer documentation sites, API reference UIs, or interactive playgrounds (Docusaurus, Mintlify, Nextra, or similar). Familiarity with cloud platforms (AWS, Azure, or GCP).
