Senior AI Engineer

Salary: £65,000 - 70,000 per year

Requirements

• We need hands-on experience building production systems with LLMs, RAG architectures, and tool use.
• We need strong software engineering fundamentals in one or more of C#, Python, or TypeScript/JavaScript.
• We need experience integrating with LLM provider APIs such as OpenAI, Anthropic Claude, or equivalent.
• We need working knowledge of embedding models, vector databases, and semantic search.
• We need familiarity with cloud infrastructure on Azure or equivalent, including deployment, storage, compute, and managed AI services.
• We need experience with source control, Git, CI/CD pipelines, and test-driven development.
• We need the ability to evaluate and benchmark AI model output quality, cost, and latency.
• Desirable: experience with agent orchestration tools such as OpenClaw or Hermes.
• Desirable: knowledge of data privacy regulations and their implications for AI systems handling customer data.

Responsibilities

• We will architect and maintain the orchestration layer that coordinates AI agents to design, write, test, and deploy production code.
• We will define guardrails, evaluation frameworks, and human-in-the-loop checkpoints that make agentic development safe and auditable.
• We will write the majority of production code using AI coding tools, treating AI as a first-class collaborator.
• We will continuously evaluate new agent frameworks, models, and tooling and recommend adoption where there is clear product or velocity benefit.
• We will design and build LLM-powered features within our platform, including natural language interfaces, intelligent summarisation, and automated insight generation.
• We will own prompt engineering, RAG pipeline design, and the retrieval architecture underpinning AI features.
• We will integrate with external model providers and evaluate when to use third-party APIs versus fine-tuned or self-hosted models.
• We will implement robust evaluation pipelines to measure output quality, latency, and cost across AI features.
• We will design and maintain embedding pipelines, vector stores, and semantic search capabilities that power AI features.
• We will collaborate with the data team on ML model training and fine-tuning where our proprietary data provides a competitive advantage.
• We will ensure AI systems meet data governance, privacy, and security standards relevant to our hospitality clients.
• We will produce clean, well-tested, maintainable code in accordance with our coding standards.
• We will participate in code review and architecture discussions.
• We will contribute to technical documentation, specifications, and internal knowledge sharing on AI-era engineering practices.
• We will identify and manage risks when AI-generated changes could affect other areas of the system.
• We will act as an internal authority on AI engineering practice and help the wider team work effectively alongside AI agents.
• We will consult with the CTO and leadership team to shape our AI product strategy and technology choices.
• We will perform research and development activities that lead to innovations in product capability, development efficiency, and platform performance.
