About the role

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 maintaining and growing its volume: strategy, a significant monthly budget, campaign structures, creative testing, and consistent, high-ROI growth, driving subscriptions through web funnels.

This is a hands-on role suited for someone who has already run Facebook at scale and keeps performance stable at high volume. You are expected to make independent, data-driven decisions, continuously test new approaches, and deliver consistent, predictable results. The bar is high and so is the upside - performance here is directly and significantly rewarded, and strong operators take on bigger scope fast.

Key Responsibilities

Channel Ownership: Own and optimize the Facebook account end to end, maintaining high subscription volume with efficient CPA and positive ROAS.

Traffic Stability: Establish stable and efficient traffic delivery on scale, working autonomously.

Testing & New Approaches: Continuously test structures, audiences, bidding, placements, and geos; pilot new approaches before performance plateaus and scale what works.

Creative Ideas: Own the creative ideas for your channel, working with the creative team to bring them to production.

Working with Data: Analyse performance down to bid level and buy each country in a wide geo mix at maximum efficiency. Build your own models and reporting.

Market Expertise: Build deep expertise in your market: advertising approaches, competitor playbooks, and emerging tactics.

AI & Automation: Automate every repeatable part of your workflow with AI, keeping manual work to a minimum.

Qualifications

Must-Have Experience

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

Budget Scale: Experience managing significant monthly ad spend with clear ROI accountability, maintaining high volumes profitably while continuing to scale.

Subscription Funnels: Experience driving subscriptions through web funnels (web-to-web) for D2C products.

Multi-GEO: Experience running and scaling campaigns across multiple countries.

Analytics: Deep command of data - you break your traffic down to its smallest components and constantly improve its efficiency.

AI Mastery: Expert-level daily work with AI tools (Claude or equivalent) - you automate processes end to end and run your channel with minimal manual work.

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

Plans ahead - builds channel strategy weeks and months out and runs the account against that plan
