Senior Performance Marketing Manager

LemFi (Series B) is building the go-to financial app for the Global South. Moving to a new country shouldn’t mean starting from zero. That's why our team of 400+ spanning 20+ countries is building a financial ecosystem that helps immigrants stay connected to home, build stability, and create wealth regardless of where they are from or where they live. What began as fast, affordable remittances is now evolving into a complete platform for multi-currency accounts, payments, credit, and long-term financial growth. With millions of users across the globe, we process over $1B in monthly transactions to 30+ countries, proving that borders shouldn't limit financial opportunity. About the role LemFi exists to serve people the financial world has largely ignored. Every campaign we run is a chance to reach a diaspora customer who needs a faster, fairer way to send money home, save in multiple currencies, or access credit for the first time. Performance marketing is not a support function here - it is one of the sharpest levers we have for scaling into new corridors and deepening product adoption in the markets we already serve. As Senior Performance Marketing Manager, you will own paid acquisition end to end across our core channels and geographies. You will set strategy, run the numbers, brief the creatives, and be accountable for CAC, ROAS and volume targets - not just the dashboards that report them. You will work closely with Product, Growth, Creative and Data to make sure every pound, dollar or naira of media spend earns its place. If you treat a budget like it is your own money, read the data before forming an opinion, and push through the noise to find what actually moves the needle, this role is for you. What you'll build and own • Own paid media strategy and execution across Meta, Google, TikTok and programmatic, covering customer acquisition and product cross-sell across LemFi's active markets. • Manage and optimise significant media budgets with a clear eye on CAC, LTV, ROAS and payback periods - make the numbers work, not just look good in a report. • Design and run a rigorous test-and-learn programme across audience segmentation, creative angles, bidding strategies and landing pages, using AI tools to accelerate analysis and iteration. • Translate campaign data into clear, actionable insight for senior stakeholders - lead with what it means and what to do next, not just what happened. • Partner with the Creative team to brief and iterate on paid assets that speak plainly to diaspora audiences across different corridors and cultures, cutting through the noise in crowded feeds. • Work cross-functionally with Product and Growth to align paid campaigns with product launches, corridor expansions and seasonal remittance peaks, so spend lands when it matters most. • Develop and maintain attribution and measurement frameworks that give the business confidence in channel contribution, flagging gaps and pushing for better data where it does not yet exist. Your experience • 5+ years of experience in performance marketing for a mobile app product, with a proven track record of managing substantial paid media budgets across at least Meta and Google, ideally within a high-growth consumer fintech, payments, or marketplace business. • Full-funnel approach to growth, naturally thinking beyond acquisition and considering the entire customer lifecycle. • Hands-on experience acquiring and retaining users for a mobile app product (iOS and Android), including working with mobile measurement partners, attribution tooling and incrementality testing. • Demonstrably strong analytical skills - you move fluently between a campaign dashboard, a spreadsheet model and a conversation with a data analyst, and you know when instinct must give
