Growth Marketing Manager, Paid Channels

Runway

7d • $150,000 - $200,000 • Remote

About The Position

We are building AI to simulate the world through merging art and science. World models offer the most clear path to general-purpose simulation, changing how stories are told, how scientific progress is made and how the next frontiers of humanity are reached. Our team consists of creative, open minded, caring and ambitious people who are determined to change the world. We aspire to continuously build impossible things and our ability to do so relies on building an incredible team. If you are driven to do the same, we'd love to hear from you.

About the role
Open to hiring remote across the US — we also have offices in New York, San Francisco, Seattle, London, Paris, and Tel Aviv.

We are hiring a Growth Marketing Manager to own paid search and the emerging bidding-platform channels end to end Google Ads today, ChatGPT Ads and whatever bids next. This is a hands-in-the-account role: you build campaigns, run experiments, manage bids and budgets daily, and defend every dollar against our cost-per-subscriber breakeven. You'll manage seven-figure budgets in spend across markets (US + international) and be the person who knows, at any moment, why the number moved.

We're an AI-native creative platform in scale mode. Paid search is one of our priority acquisition channels and we're actively expanding it — new geos, new bidding surfaces, new optimization events. You'll be the operator driving that.

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.

Nice To Haves

• 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.

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.

Benefits

• Great things come from great teams. We’d love to hear from you.
• We’re committed to creating a space where our employees can bring their full selves to work and have equal opportunity to succeed. So regardless of race, gender identity or expression, sexual orientation, religion, origin, ability, age, veteran status, if joining this mission speaks to you, we encourage you to apply.
