You’ll play a key role in designing and implementing features that empower our users to explore and visualize data with ease — all while ensuring high quality, performance, and maintainability across both frontend and backend systems.

If you care about clean code, strong UX, scalability, and enjoy collaborating on cutting-edge tools that include AI-driven features, we’d love to hear from you.

Key Responsibilities

• Familiarity with PostgreSQL and AWS (Lambda, ECS, S3, etc.) is a plus.
• Understanding of web protocols (HTTP / s, WebSockets, etc.).
• Solid skills in HTML5, SCSS, RxJS, and performance optimization.
• Experience with d3.js or other data visualization libraries is highly valued.
• Previous exposure to AI or LLM-powered features, such as LangChain / LangGraph, prompt optimization, or MCP (Model Context Protocol) is a strong plus.
• Strong UX and design intuition.
• Ownership mindset — from envisioning to deployment.
• Excellent communication and teamwork skills in English.
• Located within CET time zone for effective collaboration.
• Eligible to work in Belgium or open to a contracting setup (we cannot sponsor work permits).
