Senior Staff Product Manager, eCommerce

Liftoff is building an e-commerce advertising platform that drives app users to purchase on merchants’ e-commerce sites. The Senior Staff Product Manager will own the product’s strategy and development from its early stage through beta and general availability, including its business case, experimentation roadmap, identity and attribution architecture, and customer and partner engagement.

Responsibilities:

• Set the product strategy, quarterly goals, and success metrics, and present progress against milestones to executive leadership and finance
• Own the unit economics that define launch readiness (success metrics, traffic quality, funnel efficiency), and make the call on when the data supports scaling, pivoting, or stopping
• Decide what stays out of scope. The possible surface area will always exceed team capacity, and disciplined scope-cutting is as important as anything you ship
• Partner with GTM, sales, and account teams to define ideal customer profiles and go-to-market strategy, select and onboard customers, and turn customer intel into roadmap decisions. Represent Liftoff in customer conversations and strategic industry partnerships
• Partner with Eng leads to own the experiment roadmap, interpret A/B results, and make Go/No-Go decisions
• Diagnose full-funnel performance from ad impression through site session, add-to-cart, and purchase, and call out investigation opportunities
• Set and enforce traffic quality and creative UX standards that protect advertiser outcomes, including suppression logic and inventory quality controls
• Work with Legal to define product policy around consent handling, regional privacy requirements, customer data protection, and compliance (GDPR, CCPA, etc.)
• Develop strategic partnership and integration opportunities to ensure robust measurement and attribution
• Defend our attribution methodology and incrementality story with sophisticated performance marketers and agencies
• Lead e-commerce platform integration work end to end: pixels, server-side event delivery, order attribution, catalog ingestion, and merchant-facing installation flows

Requirements:

• 8+ years of product management experience, with meaningful time in performance advertising: DSP, retargeting platform, measurement/MMP, or ad network e-commerce products
• Hands-on depth in web and mobile identity and attribution: probabilistic matching (IP and device signals), pixels, server-to-server postbacks, and the practical constraints of browser privacy changes (ITP, fingerprinting protection) and ATT
• A track record of carrying a product from beta to GA, including at least one experience where you recommended killing or materially pivoting something based on the data
• Comfort operating in a 0-to-1 incubation environment: small, funded pilots, hands-on customer management, and shipping against explicit go/no-go criteria
• Demonstrated ML experimentation experience: you can read a confidence interval, challenge an experiment design, and make a ship/no-ship call under uncertainty
• Cross-functional leadership across engineering, ML, go-to-market, sales engineering, creative, and finance without direct authority over any of them
• Experience with the Shopify/e-commerce ecosystem: app approval, Customer Privacy API, webhooks, catalog/product feeds, or merchant-facing tooling. Familiarity with CAPI-style server-side integrations (Meta CAPI, Google Enhanced Conversions) also counts
• Familiarity with incrementality testing, MTA, or MMM, and the attribution debates (first-click vs. last-click, demand creation vs. demand capture) that agencies and DTC marketers actually have
• Executive-level financial fluency: you can build and defend a unit economics case to a senior audience and hold your ground under scrutiny
