Cryptography Architect

You will lead protocol design and evolution for MPC/TSS, signing, key management, and post-quantum migration. You will turn cryptographic research into implementation-ready designs, review implementations and threat models, guide engineers, work with external reviewers, and produce protocol and audit documentation.

Responsibilities

• Lead protocol design and evolution for MPC/TSS, signing, key management, and post-quantum migration
• Translate cryptographic papers and mathematical specifications into implementation-ready designs
• Review protocol implementations, threat models, and security assumptions before production
• Establish a repeatable threat-modeling process for protocol work
• Partner with engineers to preserve protocol intent and security properties
• Work with external cryptographic audit firms, researchers, and security reviewers
• Produce protocol specifications, design notes, threat models, and audit-facing documentation

Requirements

• Deep applied cryptography experience across MPC, threshold signatures, distributed key generation, secret sharing, ZK proofs, or related protocol areas
• Ability to read, critique, and implement cryptographic papers and formal specifications
• Experience translating research into engineering specifications
• Threat-modeling expertise
• Familiarity with production cryptographic engineering in Rust, Go, C, C++, or similar systems languages
• Clear written communication for researchers, engineers, auditors, and technical leadership

Benefits

• Equity participation
• Visa or EOR support where applicable
