About this role

Legal AI is only as good as the knowledge behind it. At Lefebvre Sdu, we've been building that knowledge for over 200 years. Day in, day out. Law by law. Word by word. As the Dutch heart of Lefebvre Group, the European leader in legal and tax knowledge, we're also developing our own platform: GenIA-L, where lawyers and tax advisors don't just get an answer, but an answer they're willing to attach their name to. More than 75,000 professionals use it daily, generating over 100 million euros in ARR across Europe.

We're looking for a Senior Software Engineer to help build that.

How You'll Move US Forward

We're bringing separate knowledge portals together into one platform, with AI as the primary way users interact with our platform. We're building GenIA-L: an agentic AI solution that understands and answers legal questions based on our own, trusted content. With you on board, the team will be able to take end-to-end ownership of its own components.

In practice, the role is backend-first: you'll take ownership of business-critical Node.js services around authentication, authorization, and user management, along with components like PDF export and chat delivery via Redis. Ownership in this role at Lefebvre Sdu means actively driving continuous improvement, stabilization, and simplification of these systems: so you won't just be keeping the lights on. Frontend work will also come up, so a solid frontend level is desired.

The product is under active development, so what you build and improve now will determine how stable and scalable this platform is a year from now.
