Growth Marketing Manager, Paid Channels

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 emerging bidding-platform channels end-to-end (Google Ads today, ChatGPT Ads, and whatever comes next). This is a hands-on role: you will 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 across markets (US + international) and be the person who knows, at any moment, why performance metrics moved.

We're an AI-native creative platform in scale mode. Paid search is a priority acquisition channel, and we're actively expanding it — new geographies, new bidding surfaces, and new optimization events. You'll be the operator driving that 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. Understand the funnel from impression → registration → subscription and identify 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 analyze geo holdouts, conversion-lift studies, and pause tests. Distinguish incremental subscribers from those we’d have acquired organically.
• Manage budget across markets — allocate and reallocate spend by market and campaign based on performance, break out international blobs, and fund high-performing geos.
• Stand up new bidding platforms as they emerge. Be first-in on the next channel and write the playbook for it.
• Report clearly. Provide daily and weekly readouts that lead with the "why," not just data tables. Partner with our analytics stack (much of this is instrumented and semi-automated) and 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-figure budgets.
• Deep Google Ads expertise — Smart Bidding, tCPA/tROAS, Performance Max / AI Max, Demand Gen, search term hygiene, quality score, and the Google Ads 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.

Bonus Points

• 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.

About Us

We are building AI to simulate the world by merging art and science. We believe world models are at the frontier of progress in artificial intelligence. Language models alone won’t solve the world’s hardest problems — robotics, disease, scientific discovery. Real progress requires models that experience the world and learn from mistakes, the same way humans do. Simulation accelerates this trial and error massively. World models offer the clearest 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 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.

We’re committed to creating a space where employees can bring their full selves to work and have equal opportunity to succeed. Regardless of race, gender identity or expression, sexual orientation, religion, origin, ability, age, or veteran status, if joining this mission speaks to you, we encourage you to apply.
