AI Developer / AI Engineer

📍 London (Hybrid – 3 days in office)


We’re hiring an AI Developer to join a high‑performing digital engineering team focused on real‑world, production‑ready AI.

This role is ideal for a software engineer who enjoys building, optimising and shipping AI features — not just experimenting with them. You’ll work on intelligent, brand‑safe AI solutions used by well‑known clients, collaborating closely with engineering, design and strategy teams.


What you’ll be working on

  • Designing and implementing agentic AI workflows and prompt strategies
  • Building RAG systems that connect LLMs to client‑specific data
  • Optimising AI performance across latency, token usage and accuracy
  • Deploying AI services into production using Python
  • Validating and benchmarking AI outputs against quality and safety standards
  • Turning emerging AI capabilities into robust, shippable product features
  • What we’re looking for

    • Strong software engineering background with solid Python skills
    • Hands‑on experience working with LLM APIs and AI orchestration
    • Experience taking AI features from idea through to production
    • A pragmatic, engineering‑led approach to applied AI


    Nice to have

    • Python for data processing or model evaluation
    • Experience with collaboration or embedded messaging platforms
    • Exposure to C# / .NET
    • Front‑end experience for conversational or prototype UIs


    Why apply?

    • Hybrid working: London office Tuesday–Thursday, remote Monday & Friday
    • Flexible working hours and strong work‑life balance
    • Competitive benefits including private medical cover, pension, income protection and enhanced parental leave
    • 25 days holiday plus bank holidays and additional Christmas closure
    • Continuous learning, training and career development
    • A collaborative, creative and engineering‑led culture


    If you’re excited by practical AI, intelligent systems and shipping real solutions, we’d love to hear from you.
