Growth Marketing Manager, Paid Channels

Runway is an innovative company focused on building AI to simulate the world by merging art and science. They are seeking a Growth Marketing Manager to manage paid search and bidding-platform channels, optimizing campaigns and budgets to drive subscriber growth.

Responsibilities:

• Day-to-day management of Google Ads and ChatGPT Ads — campaign structure, keywords, bids, budgets, negatives, quality score, geo and device splits
• Own the cost-per-acquisition number. Manage to a cost-per-acquisition target, not clicks or registrations. Know the funnel from impression → registration → subscription and where it leaks
• Run a continuous test roadmap — bidding strategies (tCPA / Smart Bidding), optimization events, ad copy, landing pages, audience and geo splits. One test, one hypothesis, one readout
• Prove incrementality. Design and read geo holdouts, conversion-lift studies, and pause tests. Distinguish incremental subscribers from ones we'd have gotten anyway
• Manage budget across markets — allocate and reallocate spend by market and campaign against performance, break out international blobs, fund the geos that earn it
• Stand up new bidding platforms as they emerge. You'll be first-in on the next channel and write the playbook for it
• Report clearly. Daily and weekly readouts that lead with the "why," not just the table. Partner with our analytics stack, much of this is instrumented and semi-automated; you'll extend it
• Work cross-functionally with creative, lifecycle, product marketing, and engineering on tracking, attribution, and landing page conversion

Requirements:

• 4+ years managing paid search, with direct ownership of seven-figures in budget
• Deep Google Ads expertise — Smart Bidding, tCPA/tROAS, Performance Max / AI Max, Demand Gen, search term hygiene, quality score, the Editor
• A track record running incrementality tests (geo holdouts, lift studies) and acting on the results — not just reporting platform-reported conversions
• Fluency in funnel economics: CAC, LTV, cost-per-acquisition, payback. You optimize to downstream value, not proxy events
• Comfort in the data — SQL or willingness to learn it, plus GA4 / Mixpanel or equivalent. You pull your own numbers
• Rigorous experiment discipline and clear, opinionated written reporting
• Subscription / freemium or consumer SaaS experience
• International / multi-market paid search experience
• Experience with MCP / AI tooling to automate redundant tasks such as daily optimizations and reporting
• Early experience with AI-native ad surfaces (ChatGPT Ads, etc.) or other non-Google bidding platforms
• Familiarity with attribution plumbing — click IDs, enhanced conversions, server-side tracking
