About the role

Key responsibilities & impact

Select and own the stack for the Music & Audio vertical: CDP, product analytics, lifecycle/messaging, experimentation, warehouse, reverse-ETL, and entitlements — including writing defensible recommendations with cost model and tradeoffs
Design event taxonomy with consistent schema and identity resolution across anonymous → free → paid → multi-device
Build and attribute the full growth funnel across paid, organic, partner, and in-product virality
Architect in-app PLG motion: viral loops, referral mechanics, upgrade prompts, and sharing hooks
Define and execute lifecycle marketing strategy: segmentation, behavioral triggers, and messaging cadences across activation, habit, and expansion
Ship free-to-paid logic: trial mechanics, paywalls, in-app messaging, and entitlement checks across web and native runtimes
Build onboarding, churn-risk, reactivation, and win-back sequences
Instrument A/B experimentation with exposure logging and statistical guardrails
Own the growth dashboard: activation, conversion, ARPU, LTV, retention cohorts, and expansion rate

Requirements

What you’ll need

6+ years of end-to-end ownership of product or growth infrastructure inside a B2C or PLG B2B company
Deep expertise in growth marketing and product lifecycle marketing — you walk in knowing how to implement it, not just what it is
Hands-on production experience across the modern martech stack: CDPs, product analytics, lifecycle/messaging, billing, reverse-ETL, and transformation layer
Proven ability to ship in-app PLG mechanics where the product itself drives growth
Proficiency in TypeScript, Node.js, Python, and SQL
Fluency with AI-augmented development tools in daily workflow (Claude Code, Cursor, Codex, or equivalent)
Experience building event taxonomies that hold up without schema drift
A history of shipping paywall and entitlement logic in production where revenue depended on it
Comfort operating without a product manager: setting milestones, owning the schedule, and escalating when needed.
