Senior Product Engineer

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.

Department Description Lending to SMEs is Allica’s primary revenue stream, and the lending product teams are central to ensuring that Allica’s organic SME lending has a sustained competitive advantage against its peers, due to superior features, processes, technology and data. Whilst a lot of the market aims to avoid the complex nature of SME businesses, we are going for it head on, designing simple and efficient solutions to the most complex problems to provide excellent and efficient customer experience. We are building best in class products and platforms, which will allow us to scale quickly to serve more UK SMEs economically.

Role Description The Senior Product Engineer will bring together innovative product design and thinking, alongside building suitable technical solutions for our customers, with an emphasis of utilizing different forms of AI in both ways of working and what we build within the lending product area. The focus of the role will be a combination of product discovery and design as well as managing the complete engineering lifecycle of the product to deployment. This role will create significant value for Allica by building agentic AI capability within lending that drives our growth further, while improving risk and productivity – with the objective of scaling up initial experimentation to significantly scaled Lending solutions. This is a hands-on role, working closely with the rest of the Lending product area, and also with various teams across the bank that drive our Lending to customers, including distribution, underwriting and operations. You will experiment and then develop solutions that improve our lending prospecting, application, credit underwriting and operational processes across products and channels. You will bring deep expertise in LLMs, prompt engineering, agent frameworks, and systems thinking along with the ability to translate into solving real world problems at scale and with a user experience focus. This is a high-impact technical product role with clear business outcomes. You’ll drive the end-to-end delivery of solutions—from idea to production—and play a pivotal role in shaping the future of how we scale Allica using AI within Lending.
