Job Description

Salary: £58,000 - 98,000 per year

Requirements:
  • Solid production experience with C# .NET, including working in established codebases and shipping changes safely.
  • Hands-on experience building with large language models, including prompt design, context engineering and structured outputs.
  • A track record of shipping quickly, with examples of taking something from idea to working software in weeks rather than quarters.
  • Experience testing or evaluating LLM outputs in a structured way and using the results to improve quality.
  • Daily fluency with AI coding tools such as GitHub Copilot, Cursor or equivalents.
  • Preferred: experience with retrieval-augmented generation, agentic workflows, tool use, vector search or embeddings in production.
  • Preferred: experience with LLM APIs across more than one provider and an understanding of their trade-offs.
  • Preferred: exposure to distributive trades, rental, retail, automotive aftermarket parts or garage management.
  • Preferred: experience modernising or extending long-lived systems, in .NET or elsewhere.
  • Preferred: familiarity with evaluation frameworks, test datasets or automated quality pipelines for AI outputs.
Responsibilities:
  • Deliver AI features end-to-end, from requirement understanding through to shipped, evaluated product capability.
  • Build AI features quickly and properly, from prompts and context design through to full LLM integration in established C# .NET codebases.
  • Make solutions production-grade with error handling, fallbacks, latency management, logging, monitoring and solid evaluation before customer release.
  • Design and build prompts, context strategies and LLM integrations for product features.
  • Work primarily in C# .NET, integrating AI capability into established codebases through clean service boundaries and sensible abstractions.
  • Prototype in days, harden in weeks, and know the difference between a corner that can be cut and one that cannot.
  • Build evaluation alongside the feature, test against real business cases, and measure quality honestly.
  • Handle the unglamorous parts well, including error handling, fallbacks when a model misbehaves, latency, token cost, logging and monitoring.
  • Work with the engineers who own each codebase, fitting in with their patterns and pipelines so the work remains maintainable.
  • Keep up as models, tools and providers change, and choose pragmatically on quality, cost and latency.
  • Share what you learn with engineers around you through code, examples and conversation.
  • Work with product managers, product owners and subject matter experts to understand the business problem properly.
  • Leave documentation in better shape than you found it so the next engineer can pick up your work without friction.
  • Contribute to shared knowledge and engineering standards as the teams AI practice matures.
