Senior Analytics Engineer - GA, GTM, Data Quality

In a nutshell, we’re all about making the world of wine a better place. We fund and source directly from independent winemakers to bring customers better quality wine for a better price. No thirsty middlemen as far as the eye can see.

It’s a different way of doing things, sure. But it works. We’re one of the UK’s favourite wine clubs, shipping over 1 million (!) cases a year to curious wine lovers. And with an ambitious road ahead, we’ve got no plans on plugging the cork on growth.

Our global team (we have offices in the US and Australia, too) is entrepreneurial by nature, obsessive about customer experience and driven by performance. All things that make Naked a great place to grow both personally and professionally. And yes, we like wine. A lot.

It takes a village to be Naked. That’s why we’re always on the lookout for eager talent to join the club. And now, our team is looking for a Senior Analytics Implementation Engineer to join the fun.

In this role, you will own the end-to-end web analytics tracking stack across multiple markets. From data layer architecture through to QA, post-deployment monitoring, and business adoption, you’ll ensure our digital properties deliver accurate, actionable data across the Google ecosystem and connected platforms. This is a hands‑on technical role for someone who combines deep GA4 and GTM expertise with a rigorous approach to data quality, and the communication skills needed to embed analytics into day‑to‑day decision‑making.

So if you’re keen to help us take the guesswork out of enjoying great wine (that’s what we’re passionate about), there’s a Naked welcome pack with your name on it. Together, we’ll take Naked Wines to the next level – and share our not‑so‑well‑kept secret with the world.
