ABOUT US

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.

- Multi-GEO expertise: experience running and scaling campaigns across multiple countries and regions, and making independent, data-driven scaling decisions.

- Strong analytical skills: solid command of CPA, ROAS, and cohort analysis, plus proficiency in tools like Omni/Tableau/Mixpanel and the ability to build custom performance analyses.

- Meta platform knowledge: deep understanding of account structures, audience targeting, bidding strategies, and creative testing methodologies.

- AI and automation: experience automating user acquisition workflows with AI, automated rules or scripts, and a mindset of constantly looking for ways to work smarter.

- Autonomous and proactive: you take ownership, thrive in a fast-paced environment, and spot opportunities for testing, optimization, and growth.

- Growth mindset: strong motivation to learn, experiment and scale, with a focus on long-term performance.

- Clear communication: strong English, with the ability to present insights, results and recommendations to stakeholders.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
