Senior User Acquisition Manager; TikTok

Senior User Acquisition Manager

We are looking for a Senior User Acquisition Manager to own and scale Tik Tok 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.

• Own and optimise the Tik Tok ad account end to end — structure, bidding, budget allocation, scaling.
• Drive efficient CAC and positive ROAS while sustainably increasing spend.
• Open and scale new geos systematically — prioritise, test, and expand across a worldwide market map.
• Prepare and present a clear weekly channel strategy with performance context and next moves.

• Run a high-velocity creative testing pipeline to identify winning angles, hooks, and formats.
• Brief the creative team with data-driven feedback on what to produce next and why.
• Manage creative fatigue proactively — detect decay early, rotate and scale winners fast.

• Build custom performance models, analyses, and reporting in Excel, Tableau, and Mixpanel.
• Partner with the data team to apply attribution insights to scaling decisions.
• Own the channel testing roadmap: audiences, bidding strategies, and landing funnels.

• Track Tik Tok platform changes, ad-product releases, and policy updates that affect performance.
• Research market trends, competitor creatives, and paid-social best practices.
• Identify growth opportunities and bring tested proposals, not just observations.

• 3+ years of hands-on paid social experience, with Tik Tok as a primary channel you have owned.
• Experience managing $200k+ in monthly ad spend with clear ROI accountability.
• Proven track record scaling budgets efficiently while maintaining strong ROAS on Tik Tok.
• Experience driving subscriptions through web funnels (web-to-web) for D2C products (optional).
• Multi-GEO expertise — running and scaling campaigns across multiple countries and languages, with independent scaling decisions.
• Deep Tik Tok platform knowledge: account structures, audience targeting, bidding strategies, and creative testing methodology.
• Advanced Excel skills plus proficiency in data — you build your own performance models and frameworks rather than waiting for reports.

• 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 Tik Tok's nonstop testing cadence and multiple parallel work streams without letting quality slip.
• Growth-oriented — experiments continuously and scales what works for long-term performance.
• Clear, direct communicator — presents insights, results, and recommendations to stakeholders in strong English.
