Senior Data Analyst in London

Zilch is a payment tech company on a mission to create the most empowering way to pay for anything, anywhere. Combining the best of debit, credit and savings, we give our customers the option to earn instant cashback or spread the cost of pricier purchases, completely interest-free and with no late fees. We started in 2018 with a small team and a big dream - to make credit accessible to all. Since then, we have achieved double unicorn status and taken on more than 5 million customers. There are some exciting projects coming up and we have big growth plans.

At Zilch, data is a core driver of company strategy. We are looking for a Senior Data Analyst to join our Core Data team, playing a key role in shaping how insights, metrics, and analytics are delivered and consumed across the business. This role focuses on building foundational analytics capabilities that enable product and business teams to make better decisions. You will work closely with Services Ops, Analytics Engineering, and Data Engineering teams to define trusted metrics, develop scalable reporting and experimentation frameworks, and deliver deep-dive analyses on company-wide priorities.

You will be a hands-on, highly technical individual contributor, comfortable operating in ambiguity and influencing without authority. While this role does not include direct line management, you will act as a senior voice in the team - setting standards, mentoring peers, and helping shape the future direction of analytics at Zilch.
