About the role

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

Responsibilities

Channel Ownership & Performance

• Own and optimise the TikTok 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.

Creative Testing & Collaboration

• 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.

Analytics & Experimentation

• 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.

Market & Platform Intelligence

• Track TikTok 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.

Qualifications

Must-Have Experience

• 3+ years of hands-on paid social experience, with TikTok 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 TikTok.

• 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 TikTok 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.

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 TikTok's nonstop testing cadence and multiple parallel workstreams 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.
