The job

Plan, execute, and scale web user acquisition campaigns across Meta (Facebook/Instagram)— 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 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
