We’re Zopa.   We started our journey back in 2005, building the first ever peer-to-peer lending company. Fast forward to 2020 and we launched Zopa Bank.

Find out more about our fantastic offerings at Zopa.com!    We’re incredibly proud of our achievements and none of it would be possible without the amazing team here. It’s not just industry awards we’re winning, we’ve also been named in the top three UK’s Most Loved Workplaces.    If you embrace unconventional challenges, are unafraid to think differently and are driven to make an outsized impact, you’ll thrive here at Zopa, so join us, and make it count. Want to see us in action? Follow us on Instagram @zopalifeThe roleWe’re looking for a Senior Product Analyst to join our AI Tribe. This is a hands-on, builder-style role for someone who thinks in experiments, writes code daily, and is as comfortable building a prototype evaluation framework as they are presenting findings to a product lead. The role is technical at its core: you’ll be writing SQL and Python to dig into enrichment performance, building evaluation pipelines to test AI-driven approaches, and prototyping experiments that push the accuracy of our transaction intelligence forward. At the same time, this isn’t a data science role — you’ll be expected to prioritise ruthlessly, move fast, and care about outcomes, not just model performance.The AI tribeThe AI Tribe sits at the heart of how Zopa turns data into intelligent products. We build and evolve the capabilities that transform raw transaction data, Open Banking data, and other behavioural signals into reliable, structured intelligence. A core focus of the tribe is transaction intelligence — how raw transaction data is enriched, categorised, structured, and made usable across the business. This includes merchant and category enrichment, data quality and consistency, and ensuring transaction data integrates cleanly into our broader data models and customer-facing products. As we move toward more AI-first ways of working, the tribe is also rethinking how transaction data should be accessed and used — not just by analysts and product teams, but by AI systems and LLM-powered tools. The work is foundational and long-term in nature: improving systems, shaping strategy, and building capabilities that compound in value over time.A day in the life... Write SQL and Python to analyse enrichment performance across merchant types, transaction patterns, and edge cases — quantifying gaps, not just flagging them Form specific hypotheses about why accuracy breaks down in certain segments and design structured tests to validate them Build prototypes: prompt variants, alternative classification logic, lightweight enrichment rules — tested and evaluated before any engineering resource is committed Design and run rigorous evaluations, including LLM-as-judge pipelines, to measure whether a change actually improves things and where it introduces new failure modes Work directly with LLM APIs to experiment with enrichment approaches — prompt engineering, structured outputs, retrieval-augmented approaches — with a clear eye on accuracy, cost, and latency trade-offs Build the feedback loops that tell the team what’s working: ground truth datasets, labelling processes, evaluation metrics Communicate findings and trade-offs clearly to Product and Engineering, translating technical results into actionable decisions Stay close to the AI landscape and proactively bring in new approaches when there’s a good reason to About you...
