Growth Marketing Operations Manager

📍London│Hybrid Does this sound like you? You're the kind of person who finds genuine satisfaction in making a system work exactly as it should, and then making it better. You think in funnels, speak fluent HubSpot, and have a healthy obsession with attribution, data quality, and conversion rates that don't make you squint in disbelief.
