ABOUT THE ROLE Wealthsimple is looking for a Lead, User Acquisition to own and scale the paid and organic acquisition engine for one of Canada's most-loved fintech apps. You'll lead a team of three and operate with real autonomy — setting strategy, building systems, and driving measurable growth across paid channels. This is a role for someone who thinks like a growth architect, not a media buyer. You'll be accountable for the full acquisition loop: channel strategy, creative testing frameworks, attribution infrastructure — all tied directly to CAC and payback targets. WHAT YOU'LL DO - Own Wealthsimple's user acquisition strategy across paid channels (Meta, Google, TikTok, Apple Search Ads) - Lead and develop a team of three working across performance, creative, and in-platform execution — setting direction, removing blockers, and building systems that compound their output - This is a hands-on role. You'll be in the ad platforms daily — analyzing performance, running tests, and making optimizations yourself. We're looking for someone who enjoys the craft of execution, not just the strategy behind it. - Build and maintain a rigorous creative testing framework — establishing kill logic, CPA thresholds, and iteration velocity to consistently surface winners - Own mobile attribution infrastructure: serve as the primary decision-maker on MMP configuration, incrementality testing methodology, and resolving discrepancies between platform-reported and true performance - Design and implement UA automation — from bid management and ad pausing logic to performance reporting — to maximize output per headcount - Own full-funnel thinking beyond the ad platforms — identifying and driving conversion improvements across the onboarding journey in collaboration with product and engineering - Establish incrementality testing programs (geo lift, platform lift, holdout tests) to build conviction in channel spend beyond last-click attribution - Maintain a clear, defensible measurement framework — including a point of view on MMP vs. platform-reported discrepancies, view-through vs. click-through attribution, and enhanced matching strategies WHAT YOU BRING Must-haves: - 10+ years in mobile user acquisition, with at least 5 years in a lead or senior individual contributor role - Hands-on experience managing significant budgets across Meta and Google Ads, with working knowledge of TikTok and Apple Search Ads - Deep understanding of mobile attribution — MMPs (Appsflyer, Adjust, or similar), SKAN, attribution waterfalls, and the practical gap between MMP and platform-reported data - Experience building or operating creative testing systems with defined KPIs and kill criteria (cost per trial, cost per install, etc.) - Comfort with automation tooling (Meta Ads API, Google Ads scripts, Claude Code) and a proven track record of instrumenting AI to scale output - Strong analytical instincts — you can tell the difference between a signal and noise, and you build your measurement stack accordingly - Experience managing a small team while remaining hands-on in the channels Nice-to-haves: - Experience working cross-functionally with engineering teams to optimize funnels and conversion rates - SQL proficiency for independent analysis and funnel diagnostics WHY WEALTHSIMPLE? 🌸 Top-tier health benefits and life insurance 📈 Long-term group savings with employer match, through Wealthsimple for Business 🌴 20 vacation days, 4 wellness days, and unlimited sick and mental health days per year ✈️ 90 days away: work outside Canada for up to 90 days per year 👥 Employee resource groups, including Rainbow (2SLGBTQ), Women of WS, and Black at WS 🌎 We are a hybrid team with over 1,500 employees across North America.
