About The Position

Handshake AI connects frontier AI labs with the domain experts they need to train their models—PhDs, engineers, lawyers, doctors, and more. When a lab needs thousands of specialists activated within days, our growth team makes it happen. We’re looking for a Senior Growth Marketing Manager with a focus on paid social to own acquisition channels end-to-end, scale LinkedIn and Meta, break into untapped platforms like TikTok, and serve as a thought partner on project-level budget strategy. This role sits within our product org, so funnel changes move fast.

$1M+ in annual ad spend managed across paid social and other paid channels
Experience launching a paid channel from scratch—business case, test structure, and scale
Ability to build channel-mix budget models from a ramp plan and CAC target

Responsibilities

Launch net-new paid social platforms (TikTok, Snapchat) from zero, with structured tests, clear exit criteria, and a scaling plan for what works
Take 1–2 existing channels off our current Growth Marketer’s plate, contributing to Google and Reddit alongside your paid social focus
Respond to same-day campaign needs—when delivery ops surfaces a ramp requirement, campaigns are live within hours
