Supply Operations Lead

Description About Loop Me Loop Me  is an AI company solving one of advertising's hardest problems: making brand advertising actually measurable — and making it perform. Our platform runs patented machine learning models across billions of consumer signals in real time, optimising campaigns toward outcomes like purchase intent, brand lift, and foot traffic rather than proxy metrics like clicks. The result is 2–5x better performance than industry benchmarks,  operate a high-load programmatic infrastructure — processing millions of ad requests per second with sub-200ms response times globally.

This isn't a layer on top of someone else's stack; it's built from the ground up, in-house, by the team you'd be joining. Founded in 2012 and headquartered in London, we now have 400+ people across 19 cities and have sustained 40% revenue CAGR since 2018. The problems here are real, the ownership is genuine, and the scale is significant.

The opportunity

This is a hands-on, individual contributor role at the centre of Loop Me's global supply operations. You'll own the technical integration and day-to-day operational health of a portfolio of publishers across SDK, oRTB and VAST — from onboarding through to post-launch troubleshooting and revenue optimisation.

You'll work alongside a Supply Operations team spanning London, Krakow and Dnipro, and partner closely with Supply BD & AM, Product and Engineering. Following Loop Me's acquisition of Chartboost, you'll also help extend our supply operations capabilities into gaming and mobile app markets.

This role reports to the Senior Supply Operations Manager. It has no direct reports today, but is a deliberate step toward team leadership: as you build depth across the supply stack, there's a clear path to mentoring and eventually managing others.
