The Role

We're looking for a Frontend React Developer to work on the UI of our main product, as part of a small technical team alongside product managers, backend developers, and infrastructure specialists. You'll have significant say in how the frontend is built and how the product looks and feels.

The role is based at our Belval office. We work hybrid, but we're specifically looking for someone able to be on-site regularly, this matters for the day-to-day design and technical discussions with the team.

What You'll Do

• Develop and maintain the frontend of our application in React and TypeScript, using react-query, react-router, and modern state-management patterns.
• Design and build reusable components, and turn UI/UX designs into working interfaces.
• Optimize the application for speed and scalability.
• Work with backend developers on integration.
• Take the lead on UX/UI for the product, contributing your own design judgment.

What We're Looking For

• 2–5 years of experience in frontend or full-stack development, with solid React and TypeScript skills (hooks, state management).
• A portfolio that shows good frontend engineering and design sense.
• Experience with charting/graph libraries (React Flow, d3.js).
• Experience with Material UI (MUI) and react-router.
• Based in Luxembourg or willing to relocate, and available to work on-site at our Belval office on a regular basis.
• Interest in generative AI: comfortable using AI-assisted coding tools, and curious about where LLMs fit into the product.
• Fluent in English .

Nice to have:

• Familiarity with design tools such as Figma.
• Experience with testing frameworks such as Cypress or Jest.
• Basic DevOps skills: GitLab CI, Docker, Linux.
• A degree in Computer Science, Design, or a related field.

What We Offer

• Work on a real product in blockchain analytics and compliance, used by enterprise clients.
• A modern stack, with room to influence technical and design decisions.
• A small, international team based in Belval, with hybrid flexibility under Luxembourg's remote-work rules.
• Training budget, conferences, and exposure to LLMs and other new technologies.
