Senior Backend Engineer (AI & Integration Specialist)

Your Mission To engineer a high-performance, flexible digital platform that empowers marketing teams to build complex layouts without code. You will leverage an AI-first development workflow (using tools like Cursor and Claude) to accelerate the delivery of a pixel-perfect, component-driven architecture that achieves elite performance metrics (Lighthouse 95+, LCP < 2.5s) and handles complex AI interactions with graceful fallbacks. Rol Overview We are looking for a forward-thinking Frontend Developer to lead the implementation of a modernized, decoupled web ecosystem. This is not a standard website build; you will be engineering a Headless Architecture using React, Vue or Next.js (React) connected to a modern Headless CMS via GraphQL. You will bridge the gap between creative vision and technical execution, building a modular "Block-Based Page Builder" system. Uniquely, this role requires an AI-augmented approach: we expect you to utilize advanced AI coding assistants to write cleaner code, automate boilerplate, and solve complex logic faster than traditional methods. This role requires a unique blend of Performance Engineering and AI-Augmented Development. You will build interfaces that handle both real-time user queries and long-running asynchronous AI tasks, ensuring the experience remains seamless even under heavy load. Key Responsibilities • Develop the Component Library: Build a robust system of reusable UI components using modern Web frameworks such as VueJS, React or Next.js , ensuring strict adherence to the visual design system and WCAG accessibility standards. • Build the "No-Code" Page Editor: Engineer a modular block-based page builder that allows content creators to assemble flexible page layouts dynamically, decoupling content from code. • Performance Engineering (Crucial): You are responsible for meeting strict SLA targets: Lighthouse scores of 95+ and Largest Contentful Paint (LCP) under 2.5 seconds. You must master caching strategies, bundle splitting, and image optimization. • Resilient AI UI Integration: Build interfaces for Generative AI search that support Graceful Degradation. If the AI engine slows down or fails, your UI must instantly revert to standard search/content views without breaking the user experience . • Asynchronous Task Management: Implement UI patterns (notifications, toasts, progress bars) to handle asynchronous background processes (like AI content generation) so the user is never forced to wait . • GraphQL Data Layer: Architect the frontend to fetch data via GraphQL for the public site (for speed) and REST for secure backend integrations . • AI-Accelerated Development: Actively utilize AI tools (Cursor, Claude CLI, Gemini) to generate unit tests, refactor code, and rapidly prototype features. Core Skills and Competencies • Tech Stack: Deep expertise in VueJS, React.js, Next.js (Server-Side Rendering/App Router), and TypeScript. • Data Fetching: Advanced proficiency with GraphQL (clients like Apollo or TanStack Query) to minimize payload sizes. • Performance Optimization: Proven ability to optimize for Core Web Vitals (LCP, CLS, INP) and familiarity with Edge/CDN caching strategies . • AI-Assisted Workflow: Proficiency in using AI coding tools (Cursor, Claude CLI) to accelerate development cycles. • Security Awareness: Understanding of frontend security best practices (handling tokens, ensuring PII is not logged in browser consoles). • Testing: Ability to use AI tools to generate test suites for "Critical Rendering Paths" to ensure performance benchmarks are never regressed. Required Stack • Core: React.js, Next.js (App Router), TypeScript. • Data: GraphQL (Apollo/TanStack Query) for public site speed. • AI Tooling: Cursor, Claude CLI (Mandatory proficiency). • Code versioning: Git Domain of Mastery • Component-Driven Development (CDD): Breaking down complex visual designs into atomic, reusable software components. • Graceful Error Handling: Designing "Fail-Safe" UIs that function perfectly even when downstream AI services or APIs experience latency. • Generative UI Patterns: Understanding how to design interfaces that handle streaming text and variable-length answers from Large Language Models (LLMs). • Privacy-First UI: Experience implementing robust cookie consent managers and "Opt-In" tracking UI logic.
