Job description

Overview

We are looking for a Tech Lead to join our expanding AI team at Fletchers Solicitors and lead on full stack development. This role sits within a fast‑paced, high‑autonomy environment where we are rapidly prototyping, iterating, and deploying state‑of‑the‑art AI products for use across Fletchers and the wider legal sector. The team operates as a start‑up‑style unit within the wider business, reporting directly to the executive team, with a clear mandate to move quickly from idea to production.

You will be responsible for designing and driving the build of the systems and apps at the heart of production AI services in the legal sector, and leading technical teams as we expand. We have strong demand internally and externally and so the demands on our apps, and team, will grow considerably in the next year.

About Fletchers Solicitors And Our AI Initiative

Fletchers is a rapidly growing consumer law firm specialising in personal injury and clinical negligence, and with a growing practice in family and private client. Fletchers was one of the first consumer law firms to deploy a machine learning tool for legal work (in 2017) and was one of, or the first, law firm to have a dedicated AI department. Since then, we have been experimenting with a broader range of ML techniques, extending those tools already in use, and productionising new ones through our growing data science & engineering teams.

We believe that we are well positioned to leverage Fletchers’ unique legal‑medical dataset and industry expertise to build AI tools that will shape the future of consumer law. We’re building specialist tools that improve and automate live legal processes, transform how law firms like ours run, and which are used by colleagues for 90%+ of their working day.

The AI team operates as a separate unit within the wider business, reporting to the Director of AI and group CEO, with a mandate move fast from idea to production. We have a mix of data science, product, engineering, and legal engineering teams, and work alongside lawyers who run cases day‑to‑day. We are going to grow all aspects of the team significantly over the next year as we expand our internal capabilities and commercialise our technology externally, and that growth is starting with engineering.

We currently have an engineering team with 8 members, split across backend, frontend, and infra (though we are not keen on rigidly enforcing these role descriptions). They own and run our existing products, which are already live and in-use by hundreds of users (to‑date we have processed over 15 million pages of pdf documents, among other milestones).

The Role

This is for a full-stack Technical Lead, overseeing our engineering team, and reporting into the Director of AI. You’ll own the systems, services and infrastructure that enable the development, testing and deployment of our AI tools, and their transformation into marketable products. Covering frontend and backend, you’ll provide technical leadership for the engineering team, set standards, shape architecture, mentor other engineers, and you’ll lead on doubling that team in the next year. There will also be plenty of scope for forward‑deployed hands‑on development: you’ll work side by side with our internal users and external customer firms to ideate solutions, solve integrations, and drive adoption, bringing in the team as you see fit.

• Grow the engineering team from 10 to 20+, with the right structures and processes in place to ensure technical excellence as we expand
• Work side‑by‑side with internal users and engage directly with external customers, across pre‑sale, setup and integrations
