Job Specifications
Lead AI Engineer
Fully remote (UK based only)
£90,000 - £100,000 + bonus + private healthcare
Permanent - Full-time employment
This role is for an experienced AI Engineer with proven production experience building LLM-based systems for long, noisy and highly regulated text documentation, ideally within healthcare, legal or similarly regulated domains.
You will take technical ownership of NLP and LLM systems already in live use within a medico-legal platform.
The focus is on designing, building, evaluating and operating AI systems that work reliably on complex, unstructured documents, not research prototypes or prompt-only solutions.
You will remain hands-on across the full lifecycle, from problem framing and model design through to deployment, monitoring and iteration in production.
The role
You will lead the design and operation of LLM driven systems used to process large volumes of long-form, unstructured and inconsistent text common to healthcare and legal workflows. The work requires strong judgement around accuracy, auditability, explainability and regulatory constraints.
You will act as the technical lead for AI delivery, working closely with MLOps and Data Engineering teams and mentoring junior AI engineers.
Key responsibilities
Design, build and operate LLM-based systems for long, noisy and highly regulated text documentation. (Text Classification, Text Summarisation)
Own end-to-end delivery of NLP and LLM solutions from concept through to production
Build and optimise retrieval-augmented generation (RAG) pipelines over large document sets
Make clear technical trade-offs between fine-tuning, prompting and retrieval approaches
Build and maintain robust evaluation frameworks for accuracy, quality and reliability
Monitor model behaviour, performance and drift in live environments
Work with MLOps to deploy, retrain and version models using production-grade pipelines
Ensure explainability, auditability and responsible AI practices are embedded by design
Set technical standards and mentor junior engineers across the AI team
Required experience
Demonstrable experience building LLM-based systems for long, noisy, document-heavy data in production
Strong hands-on experience with NLP and LLMs, including transformers, fine-tuning and RAG
Proven experience working with highly unstructured text in regulated or compliance-heavy environments
Experience designing and running model evaluation and monitoring in production
Clear understanding of explainability, auditability and governance for AI systems
Hands-on experience with Docker and Kubernetes
Strong understanding of MLOps practices, CI/CD pipelines and model versioning
Experience in healthcare, legal or regulated domains is strongly preferred
Career progression
This role is the technical lead for the AI function, with ownership of delivery quality, standards and mentoring. As the team grows, scope can expand into broader technical leadership while remaining hands-on.
