Engineering at Ivo

Engineers at Ivo are inventors. Ivo was first-to-market with:
An AI agent that lives in MS word and edits the document for you [2023]
Ditching imprecise embeddings models in favor of agentic RAG [2023]
Large-scale LLM-based legal fact extraction [2024]
A legal assistant that can search large contract databases, without sacrificing accuracy [2024]
Clustering legal documents descended from the same family [2025]
Automatic deviation analysis to locate buried risk in huge contract databases [2025]
Merging contracts with their amendments to make a time series of “composite” contracts (a customer actually cried when we showed her this) [2025]

Role
Our software solves all these problems (and more) at scale, and our Backend Engineers make it possible.

You’ll work on:
Building systems that process and analyze millions of contracts reliably
Designing pipelines that orchestrate LLMs, data extraction, and clustering algorithms at scale
Creating the most accurate search and retrieval systems on the market
Collaborating with lawyers and product to build the newly possible when LLMs change every few months

Mission
Every major business has an in-house legal team, and all of those lawyers are overworked. 80 hour weeks, tight deadlines and contract-reading death marches are the industry norm. Up until recently, there wasn’t anything technology could do to help this situation.

LLMs have given us the ability to give these lawyers their lives back, and at Ivo, that’s our mission.

We’re building an AI-native platform to automate legal drudgery. People love our software - despite high competition, we have the highest trial win rate on the market (85%). We’re genuinely improving people’s lives, and we’re only just getting started.
