Senior User Acquisition Manager (Web)

500M+ downloads. 80M+ monthly users. A decade of building – and we’re still accelerating.

Flo is the world’s #1 health & fitness app worldwide on a mission to build a better future for female health. Backed by a $200M investment led by General Atlantic, we became the first product of our kind to reach a $1B valuation in 2024 – and we’re not slowing down.

With 7M paid subscribers and the highest-rated experience in the App Store’s health category, we’ve spent 10 years earning trust at scale. Now, we’re building the next generation of digital health – AI-powered, privacy-first, clinically backed – to help our users know their body better.

The job

• Plan, execute, and scale web user acquisition campaigns across Meta (Facebook/Instagram), Google Ads, TikTok, and Snapchat — building a scalable UA engine 
• Own your strategy and KPIs end-to-end: we provide the resources and the "why," you define the "how." No hand-holding, no micro-management — just results
• Monitor and optimize account structure, bidding models, and audience segmentation across platforms
• Lead creative testing frameworks — build and manage scalable systems for testing high volumes of creatives, identify what wins and why, and replicate success at scale
• Drive incremental growth through performance-focused strategy and rapid experimentation
• Own dynamic budget allocation to maximize ROAS 
• Use AI tools and automation to streamline reporting, creative testing analysis, campaign optimization, and other recurring UA workflows
• Collaborate closely with analytics, creative, MarTech, and growth teams — guide creative focus, forecast asset delivery, and write clear technical requirements
• Dig into LTV, monetization, and web funnels; when a number moves, you're the first to ask why
• Generate insights from performance data, proactively surface opportunities, and produce regular performance reports and strategic recommendations
• Stay current on industry trends, platform updates, evolving privacy regulations, and emerging AI capabilities relevant to performance marketing

Must Have

• 5+ years of performance marketing experience in user acquisition, ideally in high-growth environments
• Expert-level experience managing campaigns across Meta Ads and/or Google Ads (incl. DemGen/YT) at scale, with hands-on experience in TikTok Ads and/or Snapchat Ads
• Proven track record managing significant monthly budgets and optimizing for ROAS, CPA, and LTV
• Solid understanding of web attribution principles and experience with tracking/analytics platforms
• Proficiency in BI tools (Looker, Tableau, PowerBI, or similar); comfortable pulling and analyzing data via SQL and/or advanced Excel or Google Sheets
• Practical experience using AI tools to automate or accelerate marketing workflows — reporting, creative analysis, campaign optimization, or process automation more broadly
• Strong communication and project management skills — able to sell ideas and negotiate priorities cross-functionally with stakeholders who don't report to you
• Comfortable with ambiguity: when the roadmap shifts or a problem has no clear playbook, you build the solution rather than wait for one
• Direct communicator who gives and welcomes honest feedback; willing to challenge a broken process or a wrong call
• You care about how UA affects LTV, product retention, and the business bottom line — business owner first, media buyer second
• Upper-intermediate or advanced English proficiency
• Ability to conduct market research and competitor analysis
• Experience in healthtech, wellness, or other strictly regulated verticals is a strong advantage
