As a Senior Software Engineer (m/f/d), you will be working for our Legal & Regulatory division where we help legal and compliance professionals enhance productivity, mitigate risk, and solve complex problems confidently. There are hundreds of thousands of lawyers across Europe - and at Libra, we’re transforming how they work. Our AI platform combines deep legal reasoning with cutting‑edge generative technology, fundamentally changing how lawyers research, draft, and deliver legal work.

About the role

We are looking for exceptional engineers to join our fast‑growing team automating knowledge work for legal professionals. As a Senior Full Stack Engineer, you’ll play a central role in developing our product and have high impact and ownership over key product features. You’ll work end‑to‑end across the stack, contributing to both backend and frontend development in a lean, agile environment. This is a unique opportunity to shape the future of legal tech by building intelligent, scalable solutions that empower professionals and transform workflows. In your role you’ll be part of a highly skilled technology organization and a fast‑growing product organization. An ambitious and thrilling place to be as you’ll be essential to both strategic alignment and local execution. You’ll be working at the vibrant Merantix AI Campus in Berlin, surrounded by a community of AI innovators. We value collaboration, curiosity, and a bias toward action.

What you’ll do

• Design, implement, and maintain product features across the stack—from backend APIs to frontend interfaces.
• Collaborate closely with product and design teams to deliver intuitive, high‑performing user experiences.
• Ensure code quality, security, and scalability through best practices and thoughtful architecture.
• Contribute to technical decision‑making and help shape the engineering culture.
• Explore and integrate AI tools and agents to enhance developer productivity and product capabilities.

• Experience using AI coding agents like Cursor or Claude Code.
• Bonus: You’ve built or contributed to LLM-powered products.
• Skills: Entrepreneurial mindset with strong ownership and urgency.
• A pragmatic approach to problem solving.
• It’s more important to you to solve the problem than to use new/hyped technology.
• Accountability and commitment to high‑quality outcomes.
• Excellent communication in English; German is a plus.
