Responsibilities

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.

First impressions matter: Wallets are responsible for a user's first impression with crypto and onboarding new users into crypto. By ensuring that a user has a great first-time experience with crypto, we can help supercharge the growth of the entire ecosystem.
Make crypto easier to navigate: There is no easy way for a user to discover and navigate all that crypto has to offer. Wallets have a unique opportunity to help users not only onboard to crypto but also stay retained by exploring new things to do.
We live in a multi-chain world: We currently support Solana, Ethereum, Polygon and Bitcoin with more networks to come in the near future. We are focused on creating a unified, multi-chain crypto experience for users.
