Allica Bank

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.

Abound

About Abound We’re redefining consumer lending in the UK, and beyond. Using advanced AI and Open Banking data, we make fair, affordable personal finance available to more people. While traditional lenders rely almost entirely on credit scores, we look at the full financial picture - how much you spend, and what you can afford to repay to build a deeper, more accurate understanding of each customer's unique financial situation. And we've shown it works at scale. We’ve issued over £1.3bn in loans directly to customers while delivering market-leading credit performance - for every 10 defaults the industry expects, we see only 3. We also reached profitability just 2.5 years after launch. Backed by £2bn+ of funding from top-tier investors including Citi, GSR Ventures, and Deutsche Bank, we’re recognised as one of Europe’s fastest-growing fintechs (Sifted, CNBC). Now, we’re expanding into new markets and product lines - and we’re looking for ambitious people who want to learn fast, take ownership, and grow with us.
