Join Keith to build the future of consumer legal services using technology - adding speed, consistency and affordability.
Keith is an AI-native, full-stack regulated law firm, initially focusing on disrupting the UK conveyancing market.

We're backed by several leading UK VCs and have experienced founding team with decades of scale-up experience, multiple exits and a track-record of building successful FMCG brands.
About the Role
We're looking for a Founding Engineer to lead our engineering team. You'll set the technical direction, make key architecture decisions, and help hire and build out the team as we grow. This is a senior role - you'll have significant ownership over how Keith's platform is built and who builds it.
You Will:
* Design and own the architecture of Keith's platform - the state machine, workflow engine, API layer and data model that orchestrate every transaction
* Build and improve AI agent pipelines - document review, correspondence handling, structured data extraction
* Build internal tooling for conveyancers - inbox, document review, approval workflows, transaction oversight
* Help hire and build out the engineering team as we scale
* Work directly with founders and senior lawyers to automate complex legal workflows
We'll be working quickly to get our first product to market and then iterating rapidly to ramp up automation.
About You
* 5+ years building production software, with a strong backend emphasis
* Strong command of Python, TypeScript and React/Next.js
* Experience with AI agent orchestration frameworks (LangGraph, OpenAI Agent SDK, or similar)
* Strong architectural judgement - you'll be making foundational decisions about the stack, data model and system design
* Experience hiring and managing engineers
* London-based with existing legal right to work in the UK, without requiring visa sponsorship
Why Keith
* Join a small, senior founding team building one of the first AI-native regulated law firms from scratch
* Founding team with a proven track record - including founders of one of the UK's fastest growing consumer brands
* Have real ownership and help redefine how legal work gets done
* Collaborate with senior lawyers and technologists to automate complex workflows at scale
* Work at the frontier of AI and law - move fast, experiment, and shape the product
