🐘 About Liftoff
Our Mission: Making the world a better, healthier place by gamifying fitness
Liftoff is the Duolingo of fitness, empowering anyone to start and stay at the gym, so that they develop healthier and powerful habits.
We're a mission-driven team of young founders who move fast, own the details, and do the work. We're fully bootstrapped and built this company from zero to $8M+ in ARR in under two years, and have done so profitably.
If you're excited to help build a world-class team, shape a high-performance culture, and make a real impact alongside people who are deeply committed, we'd love to meet you.
🌟 About the Team
You'll join the Product team and work closely with the Head of Product, partnering with Growth, Creative, and Engineering as needed.
Our product grows when people love it enough to bring others in. This role exists to unlock that, through better sharing, stronger social systems, and features people genuinely want to spread.
The team values ownership, speed with rigor, and a strong PM mindset. The best work here comes from people who identify problems independently, propose solutions clearly, and ship end-to-end.
🎯 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.
