As a Senior AI Engineer at Libra, you play a central role in developing and improving our core product. You build end-to-end product features leveraging the most advanced LLMs via API—from chat-based interfaces to complex behind-the-scenes integrations. You work closely with our Product, Legal Engineering, and Design teams to translate user needs into elegant, performant, and secure AI-driven experiences used daily by lawyers across Europe.
## What you'll do
- Design, implement, and maintain AI-driven product features end-to-end using LLM APIs
- Develop both visible chat-based UX flows and invisible AI integrations that enable Libra's core functionality
- Build and optimize RAG systems, including document parsing, semantic chunking, and retrieval pipelines
- Build scalable, maintainable backend systems with FastAPI and modern Python tools
- Design and implement agent orchestration systems for complex, multi-step legal workflows
- Build infrastructure for evaluation and benchmarking, including continuous monitoring and alerting to ensure quality across all AI-driven features (e.g., with Langfuse)
- Ensure high standards of security, reliability, and data privacy across all systems
- Work 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-driven engineering culture where simplicity and speed matter
