Senior User Acquisition Manager (Meta Paid Traffic)

About the role

Ruby Labs is looking for a Senior User Acquisition Manager to take full ownership of Meta paid traffic and drive subscriptions through web funnels within a single project. Meta is the core channel, with room to expand into AppLovin, X, TikTok and Snapchat. You will manage 7-figure budgets across multiple GEOs, decide what to test, scale and cut, and be accountable for results measured on CPA, ROAS and cohorts.

Key responsibilities

• Manage and scale paid social campaigns on Meta end to end: account structure, bidding, budget allocation, optimization and scaling.
• Expand into additional sources (AppLovin, X, TikTok, Snapchat) and find new growth levers: audiences, formats, placements and campaign types.
• Scale spend across multiple GEOs while holding CPA and ROAS targets.
• Run structured creative testing with the creative team, with clear hypotheses and simple scale/kill rules.
• Work with the data team on reports, cohort analysis and deep dives, diagnosing drops and spikes quickly.
• Manage signal quality: conversion events, event value, purchase optimization and attribution.
• Protect account health: ad account structure, backups and policy compliance.
• Work with platform reps on betas, new campaign types and escalations.
• Use AI and automation (Claude, scripts, workflows) to speed up builds, reporting and optimization.
• Prepare a clear strategy, document tests and learnings, and track market trends and competitors.

Required profile

• 3+ years of hands-on paid social experience, with Meta as the main platform; TikTok, Snapchat, Pinterest or AppLovin experience is a plus.
• Experience managing $500k+ in monthly ad spend with consistent optimization and sustainable growth.
• Experience running campaigns across multiple countries and regions, making independent, data-driven scaling decisions.
• Strong English, able to present insights and recommendations to stakeholders.
• Located within approximately +/- 4 hours of CET (Central European Time).

Required skills

• Deep understanding of Meta account structures, audience targeting, bidding strategies and creative testing.
• Proficiency in tools such as Omni/Tableau/Mixpanel and ability to build custom performance analyses.
• Experience automating user acquisition workflows with AI, automated rules or scripts.

What we offer

• Remote work from anywhere, with unlimited paid time off and paid national holidays.
• Company-provided MacBooks for employees who need them.
• Flexible independent contractor agreement with tax advantages and reduced employment obligations.

The interview process includes a recruiter screening (40 minutes), a technical interview (90 minutes) and a final interview (60 minutes).
