Product Engineer - Growth

## About the Role We're hiring a Growth PM (Virality & Social) to own the systems that turn engaged users into growth engines. Your core focus areas: - Referral loops and word-of-mouth mechanics - Feature sharing and viral content surfaces - Friend systems, social graphs, and community features - Global app events that drive engagement spikes and organic spread - Measurement infrastructure to understand what's actually driving growth This is a high-ownership role. You don't need to be an engineer, but you do need to ship. If you can build MVPs yourself (full-stack, React Native, or using tools like Claude Code to get to working prototypes), that's a huge plus. Your KPIs: - D7 % of new users that came from a friend/family referral - D7 retention - D30 retention - Stickiness If you can justify building a small team (engineer(s), designer, creators) to move these metrics faster, you'll have the support to do that. ## What Success Looks Like - Referral and virality KPIs improve meaningfully and sustainably, not a short-lived spike - A clear, repeatable growth engine exists in-product: sharing flows, social systems, events, and referral loops that compound - High-velocity experimentation: ship quickly, learn quickly, scale winners, kill losers - Strong operating cadence with crisp communication on what's shipping, why, and what it did You'll be evaluated on outcomes, not activity. ## What You'll Do - Own virality and social growth end-to-end - Define measurement: instrumentation, attribution, survey alignment - Build dashboards and a weekly operating cadence around your KPIs - Design and ship high-leverage growth features - Referral loops: invites, deep links, incentive systems, sharing flows - Social systems: friend graphs, squads/teams, gym buddy mechanics, leaderboards - Feature sharing: streak sharing, workout sharing, achievement moments worth posting - Global app events: challenges, milestones, and community moments that drive organic reach - Viral features: anything that makes the product more fun to use with other people - Run a high-velocity experimentation system - Ship tests weekly (or faster) - Design experiments with clear hypotheses and success metrics - Ensure clean instrumentation so the team can trust results - Collaborate cross-functionally - Partner with Engineering to build production-quality features - Work with Design to make sharing feel effortless and native - Align with Growth/Creative when the loop needs content support - Contribute to prioritization by bringing product judgment and effort estimates ## You'll Likely Succeed If You Have We don't expect you to check every box. We care most about ownership, judgment, and shipping. - Experience shipping consumer product features (PM, founder, engineer, or hybrid) - Strong product instincts and ability to turn ambiguous problems into a test plan - Comfort with funnel math, cohort analysis, and experimentation - High standards around measurement and instrumentation - Bias toward action and iteration - Clear written communication; can document decisions, write specs, and share learnings ## Bonus Attributes - You've built referral loops, viral mechanics, or social features before - You can prototype quickly (React Native, full-stack, or AI-assisted coding) - Experience with incentive/rewards design and anti-abuse considerations - Background in consumer/social apps, understanding of network effects, sharing psychology, and retention loops - Strong taste for simple UX and copy that gets people to share ## At Liftoff, You'll Enjoy - Autonomy and Ownership: you are in charge of your time at Liftoff. Decide what you want to do, align with leadership, and go for it. - Top-of-the-Market Cash & Equity Compensation: we pay for high performers. - A World-Class Team: low-ego, high standards, and real ownership. ## Interview Process Our interview process is designed to be thoughtful, efficient, and respectful of your time. - Initial Call - Hiring Manager Screen - Functional Deep Dive / Case Study (growth loop teardown + proposed experiment roadmap) - Work week trial (putting craft, values, collaboration to the test) ## Compensation and Benefits - Competitive cash + equity (based on scope and level) - Company-paid lunch every day (if you're in office) - Health & Wellness stipend up to $300/year - Home office stipend available based on need - Lifetime Liftoff Pro membership ## Equal Opportunity Liftoff is an equal opportunity employer.
