At Libra, we're transforming how legal professionals work. Our AI platform combines deep legal reasoning with cutting-edge generative technology to help lawyers research, draft, and deliver legal work faster and smarter. In just over a year, we became one of Europe's fastest-growing legal AI companies—and in late 2025, we joined Wolters Kluwer, the global leader in legal information services. Together, we're combining Libra's AI capabilities with Wolters Kluwer's authoritative legal content to build the most powerful AI workspace for lawyers in Europe. We are expanding across new markets with full localization and deep local content integrations. This is a unique opportunity to shape the next generation of legal AI products—now at true European scale.

Role Overview

As a Senior AI Engineer (m/w/d) at Libra, you'll play a central role in developing and improving our core product. You'll build end-to-end product features that leverage the most advanced LLMs available via API—from chat-based interfaces to complex behind-the-scenes integrations. You'll work closely with our Product, Legal Engineering, and Design teams to turn user needs into elegant, performant, and secure AI-powered experiences used daily by lawyers across Europe. This is a high-ownership, high-impact role for engineers who thrive in fast-moving environments and want to shape how AI is applied to real-world knowledge work.

• Design, implement, and maintain AI-driven product features end-to-end using LLM APIs.
• Develop both visible chat-based UX flows and non-visible AI integrations that power Libra's core functionality.
• Build and optimize RAG systems, including document parsing, semantic chunking, and retrieval pipelines.
• Build scalable, maintainable backend systems using FastAPI and modern Python tooling.
• Design and implement agent orchestration systems for complex, multi-step legal workflows.
• Build infrastructure for evaluations and benchmarking, including continuous monitoring and alerting to ensure quality across all AI-powered features (e.g., using Langfuse).
• Ensure high security, reliability, and data privacy standards across all systems.
• Collaborate closely with Product and Legal Engineering to rapidly prototype, test, and refine new AI use cases.
• Stay ahead of the curve by exploring new models, tools, and techniques—including AI coding agents like Cursor and Claude Code.
• Contribute to a pragmatic, execution-focused engineering culture where simplicity and speed matter.

What You Bring

• Deep experience building products that integrate large language models (LLMs) via APIs.
• Proficiency with FastAPI, Python, and common data science packages.
• Strong understanding of software engineering and security best practices.
• Experience with modern AI developer tools (e.g., Cursor, Claude Code, Copilot, etc.).
• Bonus: experience with TypeScript and front-end development.
• Excellent communication skills in English; German fluency is a plus.
• You have an entrepreneurial mindset and a deep sense of urgency in achieving your goals.
• You're a self-starter who enjoys autonomy but thrives in a collaborative team.
• You take a pragmatic approach to problem-solving—focused on impact, not hype.
• You can balance trade-offs between fast, simple solutions and long-term scalability.
• You want to build products that make AI truly useful for real professionals.

What We Offer

• Permanent employment from day one.
• Hybrid work & flexibility: Work remotely up to 3 days per week (home office) (= 8 days a month in the office) with flexible working hours.
