Job Description
We’re seeking a driven AI Lead to take ownership of AI across one of the fastest-growing legal tech companies in Europe, leading the development and evolution of our core AI products.
This role combines applied generative AI development with AI leadership, balancing hands-on work on production systems with leading the AI team, defining the roadmap, and establishing best practices for AI across the company.
Reporting to the Head of Engineering, you’ll be responsible for the entire AI function: setting direction, building systems, and enabling the organization to effectively leverage AI. You will work closely with product and engineering leadership to deliver reliable AI features while continuously improving infrastructure, observability, and evaluation workflows across all AI products.
For a leader with strong experience building and deploying AI systems in production, this is an opportunity to own multiple AI products, scale a high-performing AI team, and shape how AI is applied across the company.
Your Challenge and Opportunity in This Role
You will define how AI is built, shipped, and scaled at JUPUS. As AI Lead, you are responsible for both strategic direction and execution, ensuring that AI systems across voice, chat, and document processing deliver real value to users.
You will lead the development and evolution of the AI across JUPUS’s three modules. The Website Chatbot turns website visitors into qualified inquiries. ‘Marie’, our AI Phone Assistant, handles inbound and outbound calls for law firms. Case File & Document AI builds the case file, then analyses incoming documents, drafts briefs and tests arguments, grounded in over a million German court rulings. You will also establish the technical and organizational foundations needed to scale AI across the company.
Expect strong ownership, fast iteration, and pragmatic decision-making, with a clear focus on building reliable, production-ready systems that improve productivity for law firms.

How to apply
The Apply button opens JUPUS's own application page in a new browser tab — applying is free, and this board never sits between you and the employer: no middleman, no form of ours to fill first.
This posting runs on Ashby, the applicant tracking system behind JUPUS's job board — the form you'll see lives at jobs.ashbyhq.com. It asks for the basics first: your name, email, and a résumé/CV upload. After that come the custom questions this employer wrote for the role — Ashby lets each team tailor its application, and some postings add a short questionnaire on top, so set aside a few quiet minutes rather than a thirty-second sprint. Because the questions change per role, re-read the requirements above before you start typing; answers that echo the exact skills the listing names are the ones that survive screening. Two practical notes: apply promptly while the posting is verified live, since teams close applications once a role fills, and use one email address for the application so your details stay under one identity.
