About the role

We are looking for a Senior User Acquisition Manager to own and scale Google as a performance channel for one of our core D2C subscription products. You will be fully responsible for the channel end to end — strategy, campaign structures, bidding, budget allocation, creative testing, and consistent, high-ROI growth across multiple geos, driving subscriptions through web funnels. Google is your primary channel, and you will also run and grow Meta as a secondary channel, applying solid paid social experience across both.

We work AI-first: campaigns are researched, built, and optimized with the help of AI agents (Claude), directed by a human expert. You are expected to use AI as your daily co-pilot — for keyword and audience research, ad copy, account audits, and automating the repetitive parts of the job.

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. For a strong operator, this role has a clear growth path — proven results lead to bigger scope, and over time, to leading the UA function.

Key Responsibilities

Channel Ownership & Performance

• Own and optimise the Google ads account end to end — Search, Performance Max, Demand Gen, Display, and YouTube.

• Run and scale Meta as a secondary channel — campaign structures, audiences, and creative testing.

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

• Own budgets and make data-driven budget allocation decisions across campaigns and geos.

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

Testing & New Approaches

• Continuously test new campaign structures, keywords, 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.

• Test and scale winning Google angles and funnels on Meta, and vice versa.

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.

• Research competitors' acquisition strategies, creatives, and channels.

Working with AI

• Use Claude and AI workflows daily to research keywords and audiences, generate and review ad copy, and audit the account.

• Build agent-based workflows that automate the repetitive parts of campaign management and reporting.

• Continuously look for ways AI can raise the speed and quality of channel operations.

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: keywords, bidding, geo-expansion, and landing funnels.

Qualifications

Must-Have Experience

• 4+ years of hands-on performance marketing experience, with Google as a primary channel you have owned.

• Experience managing $500K+ monthly ad spend with clear ROI accountability.

• Hands-on experience running and scaling paid acquisition on Meta — account structures, audience targeting, and creative testing.

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

• Deep Google ecosystem knowledge: Search, Performance Max, Demand Gen, YouTube, bidding strategies, and account structures.

• 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.

• Strong AI proficiency — you use AI assistants and agent-based workflows daily in your ads work and see AI as a force multiplier, not a threat.

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.

• AI-native — defaults to AI-assisted workflows and keeps upgrading how the work gets done.

• Ready to grow into leadership — shares knowledge, builds repeatable processes, and raises the standard for how the channel is run.

Nice to have

• Experience with additional platforms such as TikTok or Snap.

• Hands-on experience with Google Ads scripts, feeds, or automation
