This is a hybrid role. You'll be expected to join us at one of our main hubs (London or Cardiff) approximately twice a month for key team meetings, workshops, and planning sessions.

About us: In 2002, we became the first insurance comparison site. Our purpose? To make the process of sorting your insurance, utilities or personal finances as easy as possible.

Confused.com is at the cutting edge of the FinTech industry, so we’re always looking for extraordinary talent. If you love what you do, get in touch today!

As a Senior Marketing Data Scientist at Confused.com, you will be a crucial driver of business impact, bridging the gap between complex data and strategic marketing decisions.

In this role, we are looking for a strategic analytical leader who will quantify the effectiveness of our marketing strategy. You will partner closely with Marketing, Finance, and leadership to optimise our multi-million pound marketing budget and shape the future of our growth.

This isn't just a maintenance role; it's a strategic challenge. Our analytics function is on a mission to evolve from a reactive reporting team into a proactive, value-generating engine, and this role is fundamental to that shift.

You will be a key architect of this change, bringing the critical causal inference expertise needed to elevate our team's technical standards and help us generate new, high-value ideas directly from our data.

Reporting to our Head of Analytics, you will join our central Data Science team, a high-impact group of specialists that functions as an internal centre of excellence.

• Design, build, and maintain advanced Marketing Mix Models to inform strategic budget allocation.
• Apply causal inference techniques to measure the incremental impact of specific marketing campaigns and initiatives.

• Ideally, you have proven experience developing and deploying Marketing Mix Models in a commercial environment.
• Strong statistical foundation, ideally including Bayesian methods.
• A passion for building production-quality, source-controlled data products, with data engineering skills to help the team own more of its data pipelines.
• Exceptional stakeholder management and influence, with a demonstrated ability to translate complex quantitative concepts for senior, non-technical audiences.
• An ambassador for data, who can advocate for data-driven decisions across multi-disciplinary teams.
• A growth mindset and a passion for mentoring, with a desire to help raise the entire team's technical standard.
