What You'll Be Doing

Experimentation Platform: Design, implement, and maintain a feature-flag and A/B-testing framework that supports rapid launch, metric collection, and automated rollback of growth experiments
Service Development: Build and scale microservices for key growth features: referral program APIs, action-card engine, push-notification orchestration
Instrumentation & Analytics: Instrument all services with real-time metrics, tracing, and logging; partner with Data teams to ensure clean event schemas and dashboarding
Operational Excellence: Own on-call rotations for growth services, define SLAs, write playbooks for incident response, and drive post-mortem action items
Cross-Functional Collaboration: Partner closely with Product, Frontend, Design, and Analytics to translate hypotheses into backend solutions, remove blockers, and deliver end-to-end experiments
Performance & Reliability: Ensure all growth systems meet sub-100ms latency targets under load and maintain ≥99.9% uptime
