Fullstack Engineer (m/f/d)

What you'll do

• Design, build, and maintain high-quality features across the Fullstack stack, from UI to API integration
• Write clean, well-tested, production-ready code and actively participate in code reviews
• Collaborate closely with Product, Design, QA, and Backend teams to deliver cohesive, user-centric features
• Contribute to technical decisions around architecture, tooling, and best practices within the team
• Take ownership of features end to end, from planning through deployment and monitoring
• Integrate AI-powered coding agents and automated LLM-based testing into daily development cycle
• Contribute to building 'AI-First' UI patterns, working alongside the LLM Platform team on generative, prompt-driven interfaces
• Stay current with emerging AI-assisted development tools and bring relevant ones back to the team
• Break down assigned product requirements into clear, actionable engineering tasks
• Deliver work reliably within sprint commitments, flagging blockers or scope changes early
• Balance new feature delivery with addressing technical debt in the codebase

Requirements

• Minimum 5+ years of professional Fullstack development experience with modern JavaScript/TypeScript
• Solid expertise in at least one major framework (React, Angular, or Vue) and its ecosystem
• Strong understanding of HTML5, CSS3, responsive design, and cross-browser compatibility
• Experience building data-heavy UIs, ideally including real-time data visualization
• Good grasp of Fullstack performance optimization, including bundle size, rendering, lazy loading, and caching strategies
• Experience with state management patterns (Redux, MobX, Zustand, or similar)
• Working knowledge of Fullstack testing methodologies, unit, integration, and end-to-end (Jest, Cypress, Playwright, or similar)
• Comfortable working with design systems and shared component libraries
• Experience using AI-assisted development tools (e.g., Claude Code) to boost engineering productivity
• Experience contributing to Fullstack architecture decisions on production applications
• Solid understanding of APIs, RESTful services, GraphQL, and system design fundamentals
• Ability to give and receive constructive feedback through code reviews
• Great communication skills, able to explain technical decisions clearly to teammates and stakeholders
• Bias for shipping and iteration, delivering incrementally and learning from real users
• Comfortable with ambiguity and rapid change in a fast-paced environment
• Thinking in terms of leverage and reuse, not one-off solutions
• Pragmatic about trade-offs between perfectionism and speed of delivery
