About the Opportunity

Our client is rebuilding legal services around AI and data. Backed by $9M+ from a tier-1 US VC, they are building a Cursor-like experience where lawyers collaborate with intelligent agents on real legal work.

You will join a small, high-caliber engineering team growing from 2 to 5, with direct ownership over agent and retrieval systems used daily by internal lawyers.

This is an engineering-first applied AI role focused on shipping reliable, production-grade systems — not just experimentation.

What You'll Build

• Agent systems that automate legal document editing and repetitive workflows

• Retrieval pipelines that ground outputs with high-quality citations

• Deep research workflows enabling step-by-step legal investigation

• Model fine-tuning pipelines as internal data matures

• End-to-end AI features deployed into real production environments

Tech Environment

• Python (core language)

• LLM-powered and agentic architectures

• Retrieval and search systems

• Production backend infrastructure

• AI-assisted engineering workflows

What They're Looking For

• Strong production experience building AI systems in Python

• Hands-on work with LLM-powered or agentic systems

• Proven model training or fine-tuning experience

• Ability to translate ambiguous product goals into working systems

• Track record of shipping end-to-end in fast environments

Nice to Have

• Experience with vector search or hybrid retrieval

• Background in collaborative editor or document workflows

• Exposure to regulated or high-stakes domains

• Familiarity with GCP, Postgres, or Temporal

• Experience building products from zero to one

Why This Role Stands Out

• Meaningful equity in a well-funded early-stage company

• Unlimited budget for AI coding tools

• Real ownership of agentic infrastructure

• Annual Mallorca offsite + regular team gatherings

• Tight feedback loop with real legal users

If you have shipped real AI systems into production and care about making agents actually reliable, our client wants to meet you...
