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.
