What You'll Bring
- 5+ years of backend development experience in modern languages (Go, Python, JavaScript/TypeScript).
- 3+ years of hands-on blockchain development experience.
- Experience working on high-scale distributed systems.
- Understanding of microservices architecture and API design.
- Knowledge of consensus mechanisms, cryptographic primitives, and distributed systems.
- Strong problem-solving skills, attention to detail, and a collaborative mindset.
Preferred
- Experience building blockchain solutions for enterprise or institutional use cases.
- Understanding of security best practices for smart contracts and blockchain systems.
- Demonstrated ability to apply AI tools in day-to-day development.
