About the Role
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.
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
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
Benefits
- Equity participation
- Visa or EOR support where applicable
Hiring Process
Application and written screen; 45-minute intro call with the hiring manager; 90-minute protocol deep-dive and threat-model working session; cross-functional panel of 2–3 conversations; two backchannel references and offer.
