Fullstack Engineer – Fletchers Solicitors AI Location

Hybrid – primarily remote, with in‑person collaboration once per month in Manchester or Liverpool, option for more in‑person and growing London presence

We are looking for a Fullstack Engineer to join our 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.

You will be responsible for building and maintaining the backend systems and web applications that support the development, testing, deployment, and scaling of our Machine Learning and LLM‑based tools, and for helping to transform these into robust, market‑ready products. We have ambitious plans to grow the AI team significantly over the next few years as we expand our internal capabilities and commercialise our technology externally.

Fletchers is a fast-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 product ionising 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. With an ever‑expanding operation, it has also recently opened offices in London. Colleagues work primarily from home: the existing AI team is distributed across London, Manchester, Liverpool, Cambridge, and Bristol, and we typically meet in person once or twice per month in Manchester.

As a Fullstack Engineer within the AI team, you will support the design, development, and ongoing evolution of our core backend services, data processing pipelines, and frontend applications. You will play a key role in enabling rapid experimentation while ensuring that successful prototypes can be hardened and scaled into production‑grade systems.

You will work closely with product stakeholders, data scientists, and clients across multiple projects in parallel. This is a role suited to someone who is comfortable working close to the user, taking ownership of systems end‑to‑end, and making pragmatic engineering and architectural decisions in a fast‑moving…
