System1 operates an industry-leading responsive acquisition marketing platform (RAMP) powered by AI & machine learning.
The Role
The Senior Growth Strategist will drive growth for early-stage products, managing campaigns, analyzing data, and experimenting with creative strategies.
Summary Generated by Built In
We’re looking for a full-stack growth marketer who thrives at the intersection of performance marketing, technical execution, and creative experimentation. This is a hands-on role designed for someone who can take new consumer products (both ad-supported and subscription) from zero to scale — iterating quickly, experimenting relentlessly, and uncovering the breakout opportunities that drive real growth.
You’ll own the full growth stack: some days you’ll be knee-deep in attribution setup, conversion tracking, and analytics; other days you’ll be testing creative hooks, launching campaigns across ad platforms, and optimizing bids and audiences in real time. Most importantly, you’ll be hunting for growth levers — finding pockets of opportunity, validating them with rapid tests, and scaling what works.
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:
- Build and execute go-to-market growth strategies for early-stage products.
- Identify, validate, and scale high-impact acquisition channels, audiences, and creative angles.
- Launch and manage campaigns across Search, GDN, Meta, TikTok, YouTube, Native, and other paid platforms.
- Develop and run structured experiments to test messaging, funnels, and targeting hypotheses.
- Work directly with engineers or code yourself to wire up analytics, attribution, and conversion tracking (e.g., GA4, Mobile Measurement Partners (MMPs), Amplitude, etc.).
- Analyze performance data and rapidly iterate on creative, targeting, landing pages, and funnel flows.
- Create and manage short-form video ads and other creative assets that drive conversions.
- Frequently collaborate cross-functionally with leadership, product managers and engineering leads to align growth efforts with product evolution.
What We’re Looking For:
- 5-7 years experience driving growth for early-stage consumer products or startups.
- Deep, hands-on experience owning performance and spend in at least one major buying platform (e.g., Meta, Google Ads, TikTok, or programmatic)
- Deep understanding of ad platform mechanics across Search, GDN, Social, Video, and Native.
- Strong technical skills — comfortable working with tracking pixels, APIs, scripts, and analytics tools.
- Proven track record of taking a product from 0→1, finding breakout opportunities, and scaling them into meaningful revenue.
- Obsessed with experimentation and able to manage rapid test-and-learn cycles, sharing results with high levels of leadership across multiple products.
- Creative, analytical, and adaptable — able to move seamlessly from strategy to execution.
What We Have To Offer:
- Competitive salary + bonus + equity
- Generous PTO + 11 company holidays
- Open sick time
- 100% covered Medical, Dental, Vision for employees
- 401k with match
- Health & Dependent Care Flex Spending Account
- Paid professional development
- Leadership & growth opportunities
- Virtual company and team building events
