About this role

ABOUT US Ruby Labs is a leading tech company that creates and operates innovative consumer products. We offer a diverse range of opportunities across the health, education, and entertainment industries. Our innovative teams are driving the future of consumer-led products, and we're always looking for passionate individuals to join us. Learn more about our story at: https://rubylabs.com/about-us/ ABOUT THE ROLE We’re 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 additional sources such as AppLovin, X, TikTok and Snapchat. You'll manage 7-figure budgets across multiple GEOs, decide what to test, scale and cut, and be accountable for results. Performance is measured on real business metrics (CPA, ROAS and cohorts), not surface-level platform numbers. We are an AI-first team, so we expect you to use Claude and automation to move faster and to streamline your day-to-day workflows.

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 look for 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 on all channels, with clear hypotheses and simple scale/kill rules.

- Work with the data team on reports, cohort analysis and deep dives, quickly diagnose drops and spikes and act on them. - Manage signal quality: conversion events, event value, purchase optimization, attribution. - Protect account health: manage ad account structure, backups and policy compliance. - Work with platform reps on betas, new campaign types and escalations. - Use Claude and automation (skills, scripts, workflows) to speed up builds, reporting and optimization.

- Prepare a clear strategy, document tests and learnings, and keep an eye on market trends and competitors. QUALIFICATIONS - Paid social experience: 3+ years of hands-on experience managing paid social campaigns, with Meta as your main platform (TikTok, Snapchat, Pinterest, or AppLovin experience is a plus) and a proven ability to scale budgets efficiently while maintaining strong ROI. - High-budget management: experience managing $500k+ in monthly ad spend, with consistent optimization and sustainable growth.
