Product Engineer

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. By leveraging technology, we aim to automate c. 80% of the current human workload - delivering game-changing levels of client service, improved responsiveness, and reduced transaction time duration. We have ambitions to expand into other formulaic process-driven practice areas, targeting a £19B UK total addressable 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 Product Engineer to join our founding engineering team. You'll sit at the intersection of product and engineering - someone who thinks deeply about the user experience and can build it end-to-end. You'll be responsible for bringing Keith's client and conveyancer-facing platforms to life, turning complex legal workflows into intuitive, polished interfaces.

You Will:

• Build and improve Keith's client platform — task-based workflows, document handling, contract signing, real-time transaction tracking
• Build and improve the conveyancer dashboard — inbox, document review, approval workflows, transaction oversight
• Work across the full stack - from React/Next.js frontend to the state machine and workflow engine that orchestrates every transaction
• Help build, monitor and improve AI agents that handle legal document review and correspondence
• Work closely with founders and lawyers to understand user needs and translate them into product decisions
• Help shape the product roadmap and make key decisions on what to build next

We'll be working quickly to get our first product to market and then iterating rapidly to ramp up automation.

About You

• 3+ years building modern web applications, with a strong frontend emphasis and genuine interest in product and UX
• Strong command of React/Next.js, TypeScript and Python
• Comfortable working across the stack — you can build an API endpoint when needed, not just consume one
• An eye for design and detail — you care about spacing, typography and interaction quality
• Able to turn ambiguous requirements into intuitive, well-structured interfaces
• Interested in new technologies and approaches to software development including experience with coding agents
• 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
