About this Senior Media Buyer, RoadWarrior role at System1
RoadWarrior is System1's route-planning platform for drivers, field teams and the dispatchers who manage them, sold as a subscription on iOS, Android and the web.
You will own hands-on paid acquisition for RoadWarrior across Google Search, Google App Campaigns, Apple Ads and Meta, on both the mobile and web funnels, and decide how budget moves between them. Success is measured in trials that convert, subscribers still paying at month six, and Teams accounts that add drivers.
This position is an onsite role requiring you to work in our headquarters located at 4235 Redwood Ave. Los Angeles, CA 90066.
What you'll do:
Run Google Search end to end for Pro and Teams: keywords, bids, budgets and ad copy.
Run Meta: prospecting, retargeting and weekly creative tests.
Run Apple Ads and Google App Campaigns for Pro installs and trials on iOS and Android.
Optimize to trial start, trial-to-paid and Teams signup, not clicks or installs.
Build Teams demand: high-intent search, directory listings and dispatcher retargeting.
Use AI tools daily for copy, visuals and creative analysis.
Own conversion tracking and keep it reconciled with billing.
Report weekly on CAC, cohort ROAS and payback by channel, platform and plan.
The stack you'll work in:
Ad platforms: Google Ads (Search and App Campaigns), Apple Ads, Meta Ads Manager
Attribution: GA4, Meta CAPI, app-store attribution
Billing: app-store subscriptions, Stripe
Analytics and data: Amplitude, Snowflake, Sigma
Metrics you'll own:
MRR and net new MRR, Pro and Teams
MAU and paid MAU across app and web
Cost per trial and CAC per paying subscriber
Trial-to-paid conversion on the 7-day trial
Monthly churn and month-3 / month-6 retention
6- and 12-month LTV, cohort ROAS and payback period
Drivers added per Teams account
Attribution match rate
What we're looking for:
3–5 years of paid acquisition for subscription software, app and web.
Deep hands-on Google Search experience, plus working Meta proficiency.
Hands-on experience with Apple Ads (formerly Apple Search Ads) and Google App Campaigns (formerly Universal App Campaigns).
Comfortable with GA4 and conversion tracking.
A demonstrated AI workflow for media buying and creative.
Reads cohort retention and LTV curves and makes budget calls from them.
Bachelor's degree in Marketing, Communications or a related field, or equivalent experience.
Nice to have:
Selling a per-seat SMB SaaS tier alongside a consumer app.
RevenueCat, Stripe, Capterra / G2.
Amplitude, Snowflake or Sigma.
Familiarity with the gig-delivery, courier or field-service world.
Would rather fix a broken postback than write a deck about it.
