Product Marketing Manager, Affiliate & Conversions - AI Agents & Emerging Products

System1 is building the next generation of AI Agent–powered consumer products, and we’re looking for a Product Marketing Manager to own affiliate-driven growth and subscription conversion. You’ll be responsible for designing, optimizing, and scaling the full subscriber journey—from first click through trial, conversion, and long-term LTV.

​

This role sits at the intersection of performance marketing, product experimentation, and subscriber economics. You will be responsible for how external traffic converts into long-term, high-quality subscribers—not just how much traffic comes in. Success is measured in LTV, retention, and contribution margin, not top-of-funnel volume.

​

You’ll work closely with Product, Design, and Engineering to shape landing experiences, offers, trials, and lifecycle flows, using data and experimentation to drive continuous improvement. You do not need prior experience with every tool or platform listed below—we value strong fundamentals, technical curiosity, and the ability to learn fast in AI-enabled environments.

​

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:- Own and continuously optimize affiliate-driven subscriber funnels, from post-click landing pages through trials, conversion, and long-term retention.

• Source, evaluate, and scale high-quality affiliates, influencers, and content partners, with a focus on downstream subscriber value, not arbitrage-driven volume.
• Design, test, and iterate on offers, pricing, and commission structures (CPA, rev-share, hybrid models) to align partner incentives with long-term LTV.
• Partner with Product and Design on experimentation across landing pages, trials, onboarding, and lifecycle flows, using A/B tests to identify and ship improvements.
• Own tracking, attribution, and data integrity across the funnel, ensuring performance signals accurately reflect downstream conversion and retention.
• Analyze CAC, LTV, churn, and cohort behavior by affiliate, offer, and funnel variant, translating insights into concrete optimization actions.

What You’ll Bring:- 3+ years in affiliate or performance marketing roles focused on subscription or recurring-revenue products.

• Strong understanding of conversion funnels and lifecycle optimization, including A/B testing across landing pages, pricing, trials, and nurture flows.
• Hands-on experience with affiliate platforms and tracking systems (e.g., Impact, PartnerStack, Tune) and modern attribution mechanics.
• Fluency in performance analytics, including cohort analysis and metrics such as CAC, LTV, retention, and churn.
• Experience using data-first, AI-assisted workflows to analyze and optimize performance, including pulling data directly from PostHog, Stripe, and affiliate platform APIs, automating cohort, LTV, and churn analysis, and turning insights into funnel and offer changes.

Who You Are:- You operate with high urgency, agency, and a bias for action, moving quickly from insight to experiment to shipped funnel improvements, and iterating based on real performance signals.

• You pair speed with rigor, grounding decisions in clean attribution, disciplined testing, and sharp analytical judgment so each iteration improves conversion quality, not just volume.
• You embrace a “long is wrong” mindset, reducing time-to-learning cycle times across the funnel.
• You think and act like an owner, taking accountability for the full subscriber journey and its economics, including CAC, LTV, retention, churn, and contribution margin.
• You optimize for technical leverage, building repeatable systems for partner evaluation, offer testing, creative/landing iteration, and reporting that compound performance over time.
• You are growth-minded, working backward from LTV/CAC and prioritizing affiliates, offers, and experiences that produce durable subscriber value.
• You excel at constraint removal, unblocking execution across Product, Design, and Engineering, and using AI-assisted workflows to move faster while maintaining visibility and control.

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
