Overview:

We are looking for a Senior / Lead Frontend Engineer to join our rapidly expanding AI team at Fletchers Solicitors. 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.

We have ambitious plans to grow the AI team significantly over the next few years as we scale our internal platforms and commercialise our technology across the legal sector.

About Fletchers Solicitors & the AI Team

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 (a decision support system for screening incoming cases, launched in 2017) and was one of, or the first, law firm to have a dedicated AI department, which started in August 2023. 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. Tools we have built range from simple behind-the-scenes custom model inference, to agentic-AI pipelines for 'always on' monitoring, to the core user interface that some of our colleagues work on for 90%+ of their day. We're also commercialising these tools so that other specialist law firms can leverage Fletchers legal and AI expertise, and have an ambitious agenda for external growth for the next 18 months.

Fletchers is headquartered in the North-West of the UK, with offices in Manchester, Liverpool, Leeds, Southport, Bolton, Cambridge, Reading, Birmingham, Northampton, and Newcastle.
