Senior AI Engineer

About Allica Bank
Allica is the UKs fastest growing company - and the fastest-growing financial technology (Fintech) firm ever. Our purpose is to help established SMEs, one of the last major underserved opportunities in Fintech.
Established SMEs are the backbone of local communities - representing over a third of our economy - yet have been largely neglected both by traditional high street banks and modern fintech providers.
The Opportunity
Allica is the UKs fastest-growing fintech, built for a group everyone else overlooked: established SMEs — the businesses that make up a third of the economy yet have been underserved by high-street banks and consumer fintechs alike.
Reporting directly to our CTO, youll own the AI systems that turn our Voice of Customer data — the thousands of calls, conversations, and emails our customers have with us every day — into insight the whole bank can search, understand, and act on.
Its a senior, hands-on role with real autonomy. Youll take problems from a rough idea through to systems running reliably and safely in production inside a regulated bank. You wont be working through someone elses backlog; youll help decide whats worth building and then build it.
What Were Looking For
We care far more about what you can do than how long youve done it. If most of the below describes you, wed like to talk — you dont need every line.
Core Experience

• Strong software engineering background, with deep proficiency in Python.
• Experience building and shipping LLM-powered tools or agents into production — using OpenAI, Anthropics Claude, or open-source models — not just prototypes.
• Hands-on experience and understanding of embeddings, vector databases, RAG and semantic search over large volumes of unstructured text.
  

Engineering & Delivery

• Comfortable deploying, versioning, and monitoring models in production.
• Experience with large-scale data platforms or cloud warehouses (BigQuery or similar) to build and run AI pipelines.
• Full-stack enough to wire your work into a usable API or interface end to end.
  

Quality, safety & judgement

• You evaluate models rigorously — building pipelines to measure quality, accuracy, and fairness, and weighing vendor against open-source options.
• You take privacy, bias, and safety seriously, particularly where AI touches real customers in a regulated setting.
  

Nice to have

• Experience with conversational, call or transcript data
• Exposure to financial services or another regulated environment
  

How Well Work Together
Youll join a small, senior team with a direct line to the CTO and a clear mandate. We value people who are curious, take ownership, and can translate technical ideas into something the business understands and trusts. We move quickly, but we hold a high bar for quality and responsible deployment — because were a bank, and our customers rely on us.
