Job description

We're rethinking how homes work for the way people actually live, and we'd love a Specialist, Performance Marketing to join our Growth Acquisition team to help bring that vision to life, one campaign at a time.

In this role, y ou'll be paired closely with a Senior member of the team to turn strategy into real, running campaigns across assigned paid channels . This is where strategy becomes real. The details you get right ( eg : clean data, sharp QA, and campaigns that launch on time ) are what make the bigger plan work, and it's the best possible ground to grow into owning channels of your own.

What you'll be doing:

• Bring campaigns to life across your assigned channels, covering audience setup, creative uploads, tracking and QA, with guidance from the Senior Specialist.
• Keep a close eye on budget pacing day to day and escape early if something looks off or an opportunity worth chasing.
• Put agreed optimisation plans into action, from bid tweaks and budget shifts to audience refreshes and creative rotations.
• Help run structured creative and campaign tests by setting them up, tracking results, and pulling the findings together .
• Support weekly and monthly performance reporting across channel and funnel metrics, keeping it clean, accurate and always up to date.
• Contribute to campaign, audience and creative level deep dives by pulling and organising the underlying data, so the Senior team members can turn it into recommendations.
• Stay closely connected with your mentor/manager to understand what matters most, and turn that into your key priorities.
• Work with the creative and category team on requesting new assets, aligning on briefs, and making sure what comes back fits the campaigns you're running.
• Lend a hand with platform partner needs across Google, Meta, Pinterest and TikTok, from access requests to everyday troubleshooting.

What you need to succeed:

• 1 to 3 years of hands-on experience running performance marketing campaigns .
• Pass ionate in the detail of day-to-day execution, from builds and QA to pacing .
• A genuine interest in e-commerce or DTC performance marketing, and a solid grasp of the funnel from awareness through to conversion .
• Comfortable in GA4, Looker Studio or platform-native reporting to pull and organise data and keen to build toward diagnosing performance on your own.
• Curious about what actually makes an ad work. You want to learn the fundamentals of creative testing, and you care about the story each ad tells.
• Genuine customer-centricity. You think about the actual person on the other side of the ad, not just what converts them.
• An eye for detail. You catch the typo before it goes live, and you chase to finish a QA checklist.
