Job description

Locations: hybrid working model, options for primarily remote, or more in-person in Manchester or London.

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 fir st, l aw 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 are well funded through our Private Equity backers, which allows us to invest heavily in the development of sector‑specific AI tools that assist, automate, and augment our specialist legal work. 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.

• Design and drive the build of the applications and services at the heart of production AI apps (backend: Python, frontend: TypeScript and React), ensuring performance and reliability
• Build the systems that deploy, test, and improve those apps while they’re used at scale

• Work closely with our infra and infosec teams, within their frameworks while also constructively challenging and defining our own standards for AI

  • Strong interpersonal and communication skills that make you comfortable working side by side with users and customers, including in pre‑sale, onboarding, and integration settings
  • Comfortable operating in a fast‑paced environment where requirements may evolve rapidly
  • Based near London or Manchester (although the role can be primarily remote, we anticipate meeting with the whole team twice/month in Manchester, and a local team two or three times/week in a London office)
