Lendable is a UK fintech unicorn (800+ employees, profitable since 2017) building consumer finance products—loans, credit cards, and car finance—with best-in-class technology. The company is backed by Balderton Capital and Goldman Sachs and operates in the UK and US markets.
This role combines applied AI engineering, process design, and hands-on Python development. You will own solutions end-to-end: from discovery and prototyping through deployment, evaluation, and monitoring. You'll work on loosely defined problems, test ideas quickly, and scale the strongest ones into reliable production services.
Lendable has already built a chatbot handling 1M+ customer chats annually at ~70% resolution rate, completing complex account actions autonomously. The company also operates AI document parsers processing 500K documents yearly and is trialling voice AI on phone lines. In this role, you will:
- Improve chatbot quality and expand the account actions it can complete autonomously
- Expand in-house document extraction pipelines for faster, more accurate parsing
- Design LLM-driven workflows that simplify case management
- Find new opportunities to replace manual work with effective AI systems
- Own end-to-end solutions from discovery through deployment and monitoring
You will join a small, autonomous team with meaningful ownership and decision-making power, working with LLMs, retrieval systems, agents, and automation pipelines daily.
REQUIREMENTS:
- Strong engineering skills and proven experience building production systems
- Hands-on experience using LLMs in real workflows
- Experience designing and improving prompts, retrieval pipelines, agent workflows, and evaluations
- Understanding of business processes and good judgment about where AI can simplify or automate them
- Ability to structure ambiguous problems, test hypotheses, and make progress with partial information
- Clear communication skills and ability to explain trade-offs and influence stakeholders
