We’re looking for an enthusiastic and passionate (Junior/ Mid) data analyst to join us here at GWI. Not just any data analyst though. Someone ambitious and genuine, who works best in the midst of a collaborative and forward-thinking team. That’s because as a GWIer you’ll be immersed in the fast-moving world of data tech.

Who we are

GWI was founded with the knowledge that understanding your audience is really important for business. When you know who you’re speaking to and why, you can create content and campaigns that stand out to the people that matter.

Through our global online survey, we gather data on the behaviour and perceptions of consumers across the world. This provides businesses with deep, actionable insights on their audience, revealed from data they trust.

It’s been going well, too. Since launching in 2009, we’ve become one of the UK’s fastest growing target audience companies. We’re not about to stop growing any time soon. As a business, we’re on a mission to re-engineer data-driven marketing, and we’re on the lookout for talented people to join us.

Diversity & Inclusion

Imagine if our data came from just one kind of person. We’d get a very nuanced view of the world. And we definitely wouldn’t have got off the ground as a business.

We’re so lucky to live in a society where differences are celebrated – so we’d expect nothing else from our teams. In fact, the GWI office is as diverse as our global data, and it’s really important to us that it stays that way. This is a place to feel at home, express yourself freely and make your mark.
