Artificial Intelligence Engineer

Senior AI Engineer | LegalTech | Remote (UK) – Salary DoE + Equity

How do you get an LLM to reliably work across 10,000 pages of medical and legal documents?

How do you evaluate its output, reduce hallucinations and build AI systems people can actually rely on?

These are some of the problems you’ll be solving.

I’m working with a LegalTech business that has raised £7.4m and is building AI deeply into its claims management platform.

Their AI products are already being used across areas such as medical document summarisation, document extraction and querying, with a broader roadmap around AI-assisted case handling and intelligent workflows.

They’re now looking for a Senior AI Engineer to join the team and help build the next generation of these systems.

This isn’t a role where you’ll be wrapping an API around ChatGPT.

The team has built its own agent architecture and is working with AWS Bedrock, Anthropic models, RAG and large-scale document processing, with a major focus on evaluation, reliability and quality.

You’ll be hands-on across the AI stack, working on problems such as:

• Building and improving production RAG systems
• Developing agentic AI workflows
• Working with large, complex document sets
• Evaluating new models and approaches
• Building automated evaluation and quality frameworks
• Reducing hallucinations and improving groundedness
• Productionising new AI capabilities
• Improving reliability, performance and cost

What are we looking for?

• Strong hands-on AI Engineering experience
• Experience building and shipping AI systems into production
• Strong knowledge of RAG and agentic architectures
• Experience with LLM evaluation, benchmarking and AI quality
• AWS experience, ideally including Bedrock
• Strong Python engineering experience
• Comfortable owning technical problems from experimentation through to production

Nice to have

• Experience working with regulated or sensitive data
• LegalTech, HealthTech, FinTech or InsurTech experience
• Claude / Anthropic experience
• Voice or conversational AI experience
• .NET / C# exposure

The package

• Generous base salary, dependent on experience
• EMI equity
• Remote-first across the UK
• Roughly monthly travel to Yorkshire
• 25 days holiday + bank holidays
• AXA healthcare
• Opportunity to work on genuinely complex production AI problems as the platform scales

The interview process is straightforward.

An initial conversation with the team, followed by a technical deep dive into what you’ve actually built, the decisions you made and how you approach production AI systems, then a final conversation with the wider team.
