Job description

Overview

Altrincham (4 days office, 1 day WFH)

Up to £50k DOE + bonuses

We’re a £100m-a-year performance marketing agency, spending over £250k every single day across digital, TV and radio. Big budgets, high speed, and a constant focus on what actually works.

Now we’re looking for a Performance Data Analyst to help us make smarter decisions. Someone who doesn’t just build dashboards but actually digs into the data, connects the dots, and tells us what matters. You’ll be working on everything from campaign funnels and customer profiles to offline outcomes and attribution across TV and radio.

Responsibilities

• Analyse the full journey from ad spend → sign-ups → verified results
• Merge and clean data from multiple sources, spotting the stories behind the numbers
• Use historical customer data to shape targeting and segmentation
• Attribute results across digital, TV, radio and events
• Share insights in plain, straightforward language with the senior team

Qualifications

• Strong Python and SQL skills (Pandas, NumPy, joins, large datasets)
• Experience working with marketing or customer data
• Advanced Excel/Google Sheets skills
• BI tools (PowerBI, Looker, Grafana, or similar)
• A commercial mindset — not just reporting what happened, but showing why it matters

What’s in it for you

• Salary up to £55k DOE + bonuses
• Exposure to £250k/day ad spend and campaigns that generate 9-figure revenues
• 4-day office week in Altrincham HQ + Friday socials
• The chance to build systems and models that sit at the heart of a fast-growing business

This isn’t a back-office reporting role. It’s your chance to influence strategy, shape spend, and have a direct impact on multi-million-pound decisions.
