Creative Strategist

About the role

Our Company At Quantum, we connect global brands with high-intent consumers. We turn intent into action and complexity into clarity. Our Mission is clear, to help smarter, faster buying decisions. Our vision, to be the world’s most used digital comparison service, delivering value and simplicity to millions. We drive growth through data-driven affiliate marketing built for performance from day one. Every campaign is measurable, optimised in real time, and designed to scale. With in-house tech, full-stack analytics, and a compliance-first mindset, we give our partners an edge. We drive confident decisions and growth in regulated and high-growth sectors. We’ve helped ambitious brands grow faster, smarter, and globally. The Role Our Performance Marketing team is growing, and we’re looking for a Creative Strategist to join us in London. This is a performance role for someone who lives at the intersection of creative, culture and data. You’ll work across all of ur markets and verticals, turning audience insight, platform trends and performance data into creative that drives measurable growth. You’ll have real ownership. We want someone who can help us build a best-in-class creative testing engine: finding the insight, developing the hypothesis, shaping the concept, getting it produced, analysing what happened and making the next test better. We’re not looking for someone to make ads prettier. We’re looking for someone obsessed with understanding why people stop, click and convert and who wants to test those ideas at speed. You’ll work closely with our Performance Marketing and Creative teams, as well as creators and external partners. You’ll also be hands-on: comfortable briefing polished production when it matters, but equally happy picking up a phone or opening CapCut and getting a lo-fi prototype live when speed matters more. Key Responsibilities Own creative experimentation - build and run the creative testing roadmap across Meta, TikTok, Snap and emerging channels, taking ideas from hypothesis → brief → production → analysis → learning. Obsess over the customer - mine reviews, Reddit, competitor activity, customer research and performance data to understand the problems, motivations and objections behind the click. Turn insight into ideas - develop personas, hooks, angles and concepts across different stages of customer awareness, rather than endlessly iterating the same offer-led creative. Build our UGC and lo-fi engine - source and brief creators, shoot or prototype content yourself, edit when required and help us dramatically increase the diversity and velocity of what we test. Live in the platforms - understand what feels native to Meta, TikTok and Snap, monitor trends and competitors continuously, and turn relevant opportunities into testable concepts quickly. Turn data back into creative - use metrics such as hook rate, hold rate, CTR, CVR, CAC and win rate to understand why something worked, not simply whether it did. Make our learning compound - maintain a clear testing and insights system, run creative retros and make sure successful patterns travel across channels, geographies and verticals. Use AI aggressively and intelligently - apply generative AI, creative intelligence and production tools to accelerate research, ideation, prototyping and iteration without replacing the thinking behind the work. Raise the creative capability of the whole team - bring outside thinking into Quantum, coach marketers on stronger creative briefs and work as the bridge between Performance Marketing and Creative.
