About the job
Stability AI is seeking a Senior Product Engineer to lead the ground-up development of PLG growth and lifecycle infrastructure for their music and audio products. This greenfield role spans web, desktop, plugin, and mobile platforms, requiring you to select the technology stack, design the event model, implement integrations, and manage the system. The ultimate goal is to create a measurable and attributable funnel from anonymous users to paying customers and account expansion. This position is at the nexus of growth marketing, product lifecycle management, and community-driven PLG, focusing on systems that drive conversion within the product.
Responsibilities
- Select and own the technology stack for the Music & Audio vertical, including CDP, product analytics, lifecycle/messaging, experimentation, warehouse, reverse-ETL, and entitlements, providing cost models and tradeoff analyses.
- Design a consistent event taxonomy and identity resolution system across anonymous, free, paid, and multi-device user states.
- Build and attribute the complete growth funnel, encompassing paid, organic, partner, and in-product virality.
- Architect in-app PLG motions such as viral loops, referral mechanics, upgrade prompts, and sharing hooks.
- Define and execute lifecycle marketing strategies, including segmentation, behavioral triggers, and messaging cadences for activation, habit formation, and expansion.
- Implement free-to-paid conversion logic, including trial mechanics, paywalls, in-app messaging, and entitlement checks across web and native runtimes.
- Develop onboarding, churn-risk, reactivation, and win-back sequences.
- Instrument A/B experimentation with exposure logging and statistical guardrails.
- Own the growth dashboard, tracking key metrics like activation, conversion, ARPU, LTV, retention cohorts, and expansion rate.
Requirements
- 6+ years of end-to-end ownership of product or growth infrastructure in a B2C or PLG B2B company.
- Deep expertise in growth marketing and product lifecycle marketing.
- Hands-on production experience with modern martech stack components: CDPs, product analytics, lifecycle/messaging, billing, reverse-ETL, and transformation layers.
- Proven ability to implement in-app PLG mechanics that drive product growth.
- Proficiency in TypeScript, Node.js, Python, and SQL.
- Fluency with AI-augmented development tools in daily workflow (e.g., Claude Code, Cursor, Codex).
- Experience building robust event taxonomies without schema drift.
- History of shipping paywall and entitlement logic in production where revenue was dependent on it.
- Comfort operating independently, setting milestones, managing schedules, and escalating issues as needed.
