Senior Staff Product Manager, eCommerce

Liftoff•United States (Remote), CA

About The Position

Liftoff is building a new e-commerce advertising platform, and we're looking for a Product Manager to own it from zero to one. Today the product drives app users to purchase directly on merchants' e-commerce sites. You'll take the product from its current early state through beta and on the path to general availability, partnering with a dedicated engineering team, our ML organization, and go-to-market teams to set strategy, prioritize the roadmap, and decide what's in and out of scope. This is a senior, largely individual-contributor role with real autonomy: you'll own the business case, the experimentation roadmap, and the platform's identity and attribution architecture, and you'll represent Liftoff directly with customers and partners.

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

Nice To Haves

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

Responsibilities

Own the strategy and the business case
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
Drive performance through ML partnership
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
Own identity, attribution, and platform integrations
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
