AI Engineer
What we're looking for
- Experience building production systems
- Experience with AI and backend systems in Python
- Experience with LLM-powered systems
- Hands-on experience training models
- Ability to operate in ambiguity and translate goals into systems
About the role
What you’ll build:
- Document editing: An agent proposes changes and generates/applies patches to DOCX documents, built for legal reality: multiple collaborators, tracked changes, strict formatting, and high expectations for correctness.
- Search & retrieval: When a lawyer asks “search legislation” or “find similar contracts in our database,” the agent decomposes that into targeted queries, retrieves the right sources, and grounds outputs with citations.
- Deep research workflows: Solving legal problems requires iterative investigation, where agents make progress step by step while keeping their active context focused and manageable.
- Training models: Fine-tuning models becomes a necessity to optimize the above workflows. As internal data matures, the agent can learn from past interactions to become more intelligent.

About TechTree's client
This company is building the next generation of legal services. They’re an AI-native law firm, built from day one around AI and data. Legal is a trillion-dollar global industry that still operates as if software never happened. Lawyers spend too much time on low-leverage work and too little on judgment, reasoning, and outcomes. AI is now rapidly realigning what’s possible. They believe AI doesn’t replace legal judgment - it replaces the operating model around it. Firms that rebuild around this shift will define the next era of legal services; others will struggle to justify their costs as AI reshapes client expectations. They started in April 2025 and raised a $2M pre-seed followed by an $7M seed led by a tier-1 US VC. Their product is used daily by their own lawyers on real cases, creating a tight feedback loop between product and practice. With early customers and a world-class engineering team taking shape, it’s still day one - come build with them.
