Senior Software Engineer / Senior AI Engineer

Salary: £65,000 - 105,000 per year

Requirements:

• 3+ years of software engineering experience, with hands-on experience building LLM-powered applications in production, including RAG, tool-augmented agents, or agentic workflows.
• A BS in Engineering, Computer Science, or equivalent.
• Comfort working autonomously within a defined problem and pushing back when something does not make sense.
• Experience delivering in short, time-boxed cycles where validated outcomes matter more than perfect solutions.
• Experience building RAG pipelines, tool-augmented agents, and agentic workflows.
• Familiarity with prompt engineering, context management, evaluation, and observability.
• Understanding of how agents use memory, tools, and retrieval to complete multi-step tasks.
• Experience integrating AI into existing systems via APIs and data pipelines.
• Experience with AWS, Azure, or GCP.
• Experience with CI/CD, modern SDLC, TDD, and code review.
• Experience working with relational, columnar, and vector stores, grounded in sound data-modelling principles.
• Proficiency in Python, Java, TypeScript/JavaScript, SQL, and relevant AI SDKs.
• Clear written and verbal communication with technical peers and stakeholders.
• Experience instrumenting solutions to capture usage, productivity, and quality metrics against established baselines.

Responsibilities:

• Build prototypes and proofs of concept and ship agentic AI solutions to production standards within a defined technical approach.
• Implement and test tool use, retrieval pipelines, and agent workflows.
• Contribute to evaluation, observability, and guardrails for agentic systems.
• Integrate AI capabilities into existing enterprise workflows and systems.
• Maintain high code quality and documentation so patterns can be reused.
• Flag technical risks and blockers early.
• Interface with technical peers to finalise requirements and complete moderately complex bug fixes.
• Build solutions for reuse, contributing to patterns, reference implementations, and starter kits so work done in one function can be picked up by another.
• Instrument solutions to capture outcome data against baselines.
• Work alongside host-function stakeholders to ensure the build fits real workflows, not assumed ones.
• Support handover and capability-building in the host function so the solution is owned and operable after the squad moves on.
• Keep abreast of new technology developments.
• Take on related responsibilities as the squads needs evolve.

More:

We are Embedded Innovation Teams, cross-functional squads embedded within our segments to rapidly turn internal AI experimentation into validated, reusable solutions and build the capabilities we need to deliver customer value and growth. We work problem-first rather than tool-first, directly inside segment and function teams, improving the internal workflows that help our people deliver better outcomes for customers, faster. As a Senior AI Engineer, you will work as part of a cross-functional Innovation Squad inside a business function, with a focus on building production-ready AI-powered features, supporting handover and capability-building, and ensuring solutions are owned and operable after the squad moves on. We offer a healthy work/life balance, flexible hours, wellbeing initiatives, shared parental leave, study assistance, sabbaticals, and a range of employee benefits including a comprehensive pension plan, generous vacation entitlement, family leave, personal choice budget, internal communities and networks, employee discounts, recruitment introduction reward, and an Employee Assistance Program. We are a global leader in information and analytics, helping researchers and healthcare professionals advance science and improve health outcomes. Our work supports visionary science and research, health education, interactive learning, and exceptional healthcare and clinical practice, with a location in London Wall and a full-time role.
