Role Description
As a core member of Phantom’s Growth & Engagement team, you will build and operate the backend systems that power rapid experimentation, personalized engagement features, and scalable growth initiatives. You’ll own services for action cards, referral flows, push-notification pipelines, and onboarding enhancements ensuring each feature can be launched, measured, and iterated on with minimal friction.
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.
Qualifications
- 7+ Years of Backend Experience: Demonstrated success in building large-scale, high-availability systems in Node.js, TypeScript, NestJS (or similar frameworks).
- Web3/Crypto Knowledge: Familiarity with on-chain data, wallet integrations, or decentralized application patterns is strongly preferred.
- Strong System Design & Architecture Skills: Ability to translate product requirements into scalable, maintainable solutions, with a keen eye for performance trade-offs and fault tolerance.
- Leadership & Communication: Experience mentoring engineers, leading technical initiatives, and collaborating effectively with cross-functional teams.
