About the Role
We’re seeking someone to own the relationship between our product and its users from the moment they hit a waitlist through their hundredth session. Pre-launch, that means nurturing and retaining waitlists so we convert signups into activated users on day one. Post-launch, it means retention, re-engagement, and behavior nudges that increase session frequency, feature adoption, and lifetime value.
What You'll do
Pre-Launch
Own the waitlist nurturing strategy — email sequences, engagement loops, referral mechanics
Build segmentation models based on signup source, behavior signals, and engagement depth
Design and execute the launch-day activation sequence to maximize waitlist-to-active conversion
Instrument and track waitlist health metrics (open rates, click-throughs, referral rates, churn-from-list)
Post-Launch
Own retention and re-engagement across email, push, in-app messaging, and SMS
Design lifecycle campaigns tied to key user milestones (first transaction, first week, reactivation windows)
Build and optimize behavioral nudge systems — the right message at the right moment to drive the next action
Partner with product to identify drop-off points and design interventions
Run continuous A/B tests on messaging, timing, channels, and sequencing
Report on cohort retention, LTV trends, and campaign-level performance
What You Bring
Experience in lifecycle marketing, CRM, or growth marketing at a consumer app (fintech, gaming, or marketplace preferred)
Hands-on experience with marketing automation platforms (Braze, Iterable, Customer.io, or similar)
Strong analytical chops — you think in cohorts, funnels, and retention curves, not just open rates
Experience designing multi-channel lifecycle programs from scratch, not just inheriting them
Comfort with SQL or BI tools for self-serve analysis
Understanding of behavioral psychology as applied to product engagement
Bonus Points
Experience in crypto/web3 or with waitlist-to-launch conversion
