Senior User Acquisition Manager (Web)
We’re looking for a Senior User Acquisition Manager (Web) to join the team behind CleanMyMac, MacPaw’s flagship product with millions of users globally.
CleanMyMac is an all-in-one macOS utility designed to clean, optimize, and protect Mac computers. It helps users maintain peak performance, secure their privacy, and easily keep their Mac running smoothly.
As a Senior User Acquisition Manager, you will take ownership of driving new paid user growth and managing performance marketing budgets at scale. You’ll define, test, and coordinate multi-channel media strategies, lead creative testing frameworks, and independently validate new paid acquisition channels from hypothesis to go/no-go verdicts.
If you’re excited to help scale CleanMyMac’s paid growth engine and unlock the next stage of customer acquisition across Tier-1 and global markets, we’d love to hear from you.
In this role, you will:
Take full end-to-end ownership of driving new paid user growth at efficient CAC and target payback metrics.
Build quarterly media-mix plans and allocate monthly budgets across digital acquisition platforms.
Own the hands-on management and optimization of campaigns across Google Ads (PMax, Demand Gen, Search) and Meta Ads, leveraging automated and value-based bidding.
Formulate hypotheses, design testing protocols, define success criteria, and deliver go/no-go decisions for new paid acquisition channels.
Lead the creative strategy by running structured testing frameworks and briefing in-house copywriters and designers for high-velocity ad creative production.
Design holdout and incrementality tests to evaluate true channel performance beyond standard attribution.
Maintain data-tracking integrity, setting up advanced conversion signals (enhanced conversions, CAPI, Customer Match).
Apply AI tools and automated workflows to streamline competitor monitoring, search query insights, and ad optimization.
Requirements
Skills you’ll need to bring:
5+ years of experience in paid acquisition/performance marketing, with 3+ years specifically in a B2C subscription or SaaS environment.
Strong track record of driving paid customer acquisition for B2C desktop products, with a solid understanding of desktop-specific acquisition funnels and strict CAC/payback targets.
Fluency in unit economics: CAC, LTV:CAC, payback periods, break-even ROAS, and contribution margin.
Deep hands-on experience managing Google Ads (PMax, Demand Gen, Search) and Meta Ads.
Expertise in media planning, forecasting, and dynamic budget reallocation based on real-time campaign performance.
Proven ability to run structured creative testing and collaborate effectively with creative production teams.
Proficiency in advanced measurement, including incrementality/holdout testing.
Technical comfort with clean data tracking, signal setup, and conversion APIs.
High level of autonomy and a self-driven, analytical mindset.
