Backend Developer

Responsibilities

• Design and implement a Golang backend system for MPC (multi-party computation) protocol.

• Build a highly available private key sharding management and distributed signature service.

• Develop a secure full lifecycle management system for key generation, storage, and recovery.

• Implement threshold signature (TSS) and related algorithms for secure multi-party computation.

• Build an integration layer with multiple blockchains (such as Ethereum, Bitcoin, Solana, etc.)

Requirements

• More than 5 years of backend development experience, with at least 3 years dedicated to Golang development.

• In-depth understanding of the MPC/TSS technology stack and practical experience in developing production systems.
