We are looking for a Senior User Acquisition Manager to own and scale Facebook as a performance channel for one of our core D2C subscription products. You will be fully responsible for the channel end to end -strategy, scaling it to a 7-figure budget, campaign structures, creative testing, and consistent, high-ROI growth across multiple geos, driving subscriptions through web funnels.

This is a hands-on role suited for someone who runs a channel like a business, not a set of campaigns. You are expected to make independent, data-driven decisions, present a clear weekly strategy, and keep performance stable.

Channel Ownership & Performance

• Own and optimize the Facebook ad account end to end - structure, bidding, budget allocation, scaling.

• Maintain high subscription volume while driving efficient CPA and positive ROAS.

• Prepare and present a clear weekly channel strategy with results and next steps.

Testing & New Approaches

• Continuously test new campaign structures, audiences, bidding strategies, and placements.

• Identify and pilot new approaches before performance plateaus, scaling what works.

• Run structured creative testing to find winning angles, hooks, and formats.

Creative Collaboration

• Work closely with the creative team to develop high-performing ad creatives.

• Provide data-driven feedback on angles and messaging to guide production.

• Manage creative fatigue proactively, rotating and refreshing at high spend levels.

Analytics & Data

• Build custom performance models, analyses, and reporting in Excel, Tableau, and Mixpanel.

• Develop growth plans based on CPA, ROAS, and ARPU cohort data with the data team.

• Own the channel testing roadmap: audiences, bidding, geo-expansion, and landing funnels.

Must-Have Experience

• 3+ years of hands-on paid social experience, with Facebook as a primary channel you have owned.

• Experience managing six-figure monthly ad spend on Facebook with clear ROI accountability.

• Proven track record maintaining high volumes profitably while continuing to scale.

• Experience driving subscriptions through web funnels (web-to-web) for D2C products.

• Deep Meta platform knowledge: account structures, audience targeting, bidding strategies, and creative testing methodology.

• Multi-GEO experience running and scaling campaigns across multiple countries.

• Advanced Excel skills plus proficiency in Tableau and Mixpanel — you build your own performance models and frameworks.

Operating Attributes

• Autonomous and proactive - takes full ownership of the channel and operates with minimal oversight.

• Highly analytical - every scaling and kill decision is grounded in data, not intuition alone.

• Fast under load - runs multiple campaigns, tests, and reporting streams in parallel without letting quality slip.

• Always testing - looks for new approaches beyond what already works instead of defending the status quo.

• Clear, direct communicator - presents insights, results, and recommendations to stakeholders.
