About Allica Bank
Allica is the UK’s 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 UK's 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, you'll 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.
It's a senior, hands-on role with real autonomy. You'll take problems from a rough idea through to systems running reliably and safely in production inside a regulated bank. You won't be working through someone else's backlog; you'll help decide what's worth building and then build it.
What we’re looking for:
We care far more about what you can do than how long you've done it. If most of the below describes you, we'd like to talk — you don't 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, Anthropic's 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 we'll work together
You'll 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 we're a bank, and our customers rely on us.
