AI Engineer

Job description

AI Engineer – Up to £115,000 – London Hybrid (2 days a week)

A high-impact AI Engineer hire inside a fintech business building production-grade AI products from the ground up.

This is a rare opportunity to join a small, fast-moving AI team with real ownership over greenfield products — shipping GenAI applications that directly influence how a market-leading lending platform operates.

⚡ Greenfield AI | Real ownership | High-impact team

The Opportunity

Join a cross-functional AI and Machine Learning team operating like a startup within an established, publicly listed fintech business.

Projects are 80–90% greenfield. You'll bridge the gap between data science POCs and production-grade systems, owning AI products from experimentation through to live deployment.

This is a role for engineers who want to build, ship and own — not just advise.

About the Role You'll be building and shipping GenAI applications end-to-end into production.

• Own how AI systems integrate with existing product infrastructure
• Handle real-world failure states and production engineering decisions
• Collaborate closely with data scientists, platform engineers and PMs
• Contribute to best practices for AI product development across the business
• Mentor teammates and stay current in a fast-moving space

You'll work exclusively in Python with FastAPI. Strong software engineering fundamentals matter here as much as AI experience.

What You'll Be Working On

• Website chatbot and conversational AI products
• Internal AI tooling and automation
• Document processing pipelines
• RAG pipelines, LLM integrations and agent frameworks
• Taking POCs to production-grade systems at scale

Skills and Experience

• Strong Python engineering fundamentals — this is an engineering role first
• Hands-on experience with GenAI, LLMs, RAG or agent frameworks
• Product mindset with comfort owning end-to-end delivery
• Actively using AI tools in your own workflow (Claude, Copilot etc.)
• Fast-learning and motivated to move with a rapidly evolving space

Nice to have:

• Full-stack experience (JavaScript/TypeScript)
• Experience taking AI products from POC to production commercially

Location: London – Hybrid (min. 2 days/week)

Compensation: Up Up to £115k + bonus

Team: Small, collaborative, fast-moving — high ownership culture

Stage: Greenfield AI products inside an established, scaled business

We're hiring for both Mid and Senior levels — if you're genuinely building in AI and want real ownership over products that matter, this is worth a conversation.
