- Driving experimentation, monitoring, and continuous improvement of AI logic
What We’re Looking For
- 2+ years building AI agents in production
- Strong Python skills (plus some Typescript knowledge ideal)
- Experience with LangChain, LangGraph, vector databases, RAG pipelines
- Deep understanding of memory/context handling and prompt engineering
- Ability to ship, iterate, and scale intelligent systems
Nice to Have
- Fintech or financial product experience
- Experience with tool-using agents or agent monitoring frameworks
- Exposure to model fine-tuning or reinforcement learning
Benefits
- Great salary+ equity
- Work closely with a talented team of 6 engineers
- Fully remote (UK only)
