independent problem-solving abilities.

● Contribute to production reliability through on-call participation, incident response, and

post-incident follow-ups.

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 and attention to detail

● Strong verbal and written communication skills 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

● Understanding of MPC, multi-signature wallets, or other advanced cryptographic techniques
