About The Role

We are looking for Senior User Acquisition Manager (UAM) to take full ownership of TikTok acquisition for D2C products. This is a hands-on media buying role. You will be the owner of TikTok as an acquisition channel for your brand: from account structure, bidding and budget allocation to creative testing, measurement and scaling. You will work against real revenue data (CPA, ROAS, payback), not surface-level platform metrics, and you are expected to find and unlock new growth levers on your own.

We work AI-first, so we also expect you to use Claude and automation to speed up campaign builds, analysis, reporting and optimization.

Key Responsibilities

-

Own all TikTok acquisition: strategy, execution, and results.

-

Scale spend profitably across geos and funnels while holding CPA, ROAS and payback targets based on real revenue data.

-

Build and optimize account structure, conversion events, bidding strategies and budget allocation (including Smart+ / automated campaign types, Spark Ads and other TikTok formats).

-

Run a structured creative testing process: brief and iterate with the creative team, define hypotheses, decide what to kill and what to scale, and fight creative fatigue.

-

Analyze performance daily and weekly, diagnose drops and spikes quickly, and act on them.

-

Work with product, analytics and creative teams to improve funnels, signals and attribution quality.

-

Maintain account health: handle ad disapprovals, appeals and restrictions, and build prevention-first habits so policy issues are caught before launch.

-

Work with the TikTok team on betas, new campaign types, product changes and escalations.

-

Document tests, learnings and playbooks so knowledge does not depend on one person.

-

Use Claude and automation to speed up campaign builds, QA, reporting and optimization.

-

Test new Paid Social Channels, such as: OpenAI Ads, X Ads, and others.

Qualifications

Must-Have Experience

-

Senior: 5+ years of hands-on paid social / user acquisition experience.

-

Strong hands-on TikTok Ads experience as a primary channel: scaling accounts profitably, not just running tests.

-

Proven record of managing sizeable budgets independently: ideally $1M+/month on TikTok or paid social.

-

Strong understanding of subscription / app economics: LTV, ROAS, payback windows, cohorts.

-

Solid creative testing discipline and experience working with creative teams on concepts and iteration.

-

Experience with policy issues: disapprovals, appeals, account restrictions.

-

Analytical mindset: comfortable working with MMP / backend data and diagnosing performance from account-level data.

-

Ownership mentality: able to run a channel end-to-end with minimal supervision.

-

Clear, direct communication.

Strong Advantage

-

Experience with D2C subscription, health, wellness or app products, and with web-to-app / web funnels.

-

Experience with Meta or other paid social platforms alongside TikTok.

-

Experience working directly with TikTok platform reps on betas and escalations.

-

Experience building Claude, AI or automation workflows for media buying.
