Staff Product Engineer in London

About Lawhive

Our mission is to make the law accessible to everyone. The legal industry is built on technology and processes that haven’t been updated in hundreds of years - that’s why we’ve reinvented the entire model from the ground up with our own bespoke AI operating system at the core. Lawhive is a regulated law firm with an AI-native platform built to amplify expertise and revolutionise the way people practice law, leading to exceptional outcomes for clients and lawyers. Lawhive Labs is how we bring this vision to life. It’s our frontier lab that combines top engineering, design, AI and legal talent from around the world, joining forces to build the future of law. We’re backed by top-tier investors, including Google Ventures, Balderton Capital and TQ Ventures, and in December 2024, we secured $40M Series A funding round to facilitate international expansion and to grow our team, representing one of the five largest Series A rounds in Europe for 2024. We’re headquartered in London and in 2025 successfully launched in the US…and we’re just getting started.

Engineering at Lawhive

We are a team of 40 engineers and researchers, responsible for architecting, building and running Lawhive’s platform, relied on by hundreds of legal professionals every day in the UK, US, and beyond. There are lots of problems we have yet to solve, and plenty we’re not aware of yet! In the next 12 months, we’re focused on:

• Pushing the envelope on the user experience of lawyers’ AI interactions. We’re not satisfied with “chat” as a default and are inventing a new paradigm for human/machine interaction.
• Building modularity and country independence into the heart of our platform. We’ve recently expanded to the US and are building the world’s first global consumer law firm.
• Full stack AI-native legal services: we’re not only building software, we’re an AI-native law firm.
