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. Pretty great, right?

We started in 2018 with a small team and a big dream - to make credit accessible to all. Since then, we've achieved double unicorn status and taken on more than 5 million customers. There are some exciting projects coming up and we’ve got big growth plans.

Want to join us?

About The Role

You will be joining Zilch’s Product Strategy team, a high impact cross functional group at the centre of shaping our company and product direction. Our mission is to create the most compelling customer proposition, while driving sustainable growth and profitability. We operate at the intersection of Product, Risk and Strategic Finance, owning some of Zilch’s most critical KPIs. By developing a deep understanding of the product, identifying key growth drivers and analysing the end-to-end customer lifecycle, we shape strategic decisions that unlock new opportunities and accelerate the company’s trajectory.

As a Senior Data Analyst, you will turn complex data into clear, actionable insights that shape product strategy and commercial outcomes at the highest level. If you have a growth mindset, love solving challenging problems through data and thrive in a fast paced, collaborative environment, we want to hear from you.

Day to Day Responsibilities

• Take ownership of core business metrics and lead a portfolio of strategic initiatives that directly influence growth, unit economics, and profitability.
• Act as the primary data partner for the CPO and senior leaders focused on Zilch’s strategic vision, and deliver clear, impactful insights.
• Combine strategic thinking with advanced analytical skills to understand customer behaviour, key value drivers, and customer LTV levers.
• Evaluate the impact of key product bets and uncover opportunities to drive sustainable growth.
• Where possible, automate decision processes and build self‑service tools that enhance scale and efficiency across the business.
• Partner closely with the wider data team to strengthen infrastructure, improve workflows, and embed best practices that elevate the speed, quality, and commercial relevance of insights.
• Design and automate robust data models that power accurate reporting, sharpen performance tracking, and support strategic planning and forecasting.
• Help manage technical debt to ensure data pipelines and processes remain reliable, efficient, and scalable as the business grows.

What We’re Looking For

• Someone who thrives in a fast‑growing start‑up environment, is comfortable with ambiguity, able to find practical solutions, and capable of independently driving objectives to completion.
• Someone who is passionate, driven and inquisitive.
• Someone who can break down complex problems and simply communicate solutions to senior stakeholders.

Your Qualifications Should Cover

• Degree in a STEM subject.
• 4+ years of hands‑on experience as a data analyst in a strategy, commercial or product team.
• Strong communication skills, able to present findings to non‑technical stakeholders and leadership team clearly and engagingly.
• Proven experience designing and analysing large‑scale A/B experiments to inform product and business strategy.
• Proficient in SQL and familiar with the Python data stack (pandas, matplotlib, SciPy, etc.), with experience using it for analytics and automation.
• Solid understanding of advanced analytical methodologies, with hands‑on experience applying them to A/B testing and advanced data analysis.
• 1+ years of experience in data modelling with DBT, with a strong understanding of DBT best practices.
• Highly motivated and energised by the opportunity to make a positive impact on our customers and Zilch.
