About Silence Laboratories
Silence Laboratories helps developers build secure digital wallets by distributing private key management across multiple devices. With it, teams can create wallets that work even if one device is lost, protect users from single points of failure, and add advanced security without sacrificing user experience. Silence Laboratories makes wallet security more robust for both consumer and enterprise applications.
Skills
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.
