Quick Take

Strengths
Workplace award winnerNamed one of the UK's Best Workplaces in Advertising, Media & Marketing by Great Place to Work UK in 2026.
Top workplace for womenRanked 22nd on the UK's Best Workplaces for Women list in 2026.
Watch out
Lean tech departmentThe organization's reported technical staff represents just two team members across the company.

Things to consider

Small technical footprint — Engineering and development represent a small fraction of the overall headcount, meaning technical roles may lack deep internal peers.
Agency delivery pace — Handling multiple high-profile retail and consumer clients often demands tight turnaround times and fluctuating project scopes.
