Zero Knowledge Web3 Jobs in North America

Blockstream was founded in 2014 by Dr. Adam Back and a group of fellow cryptographers and engineers passionate about Bitcoin and its potential to change the future of finance. Focusing on building fundamental Bitcoin infrastructure, Blockstream quickly grew into one of the leading technology power houses of the industry

Through our sidechain technology (the Liquid Network), wallets (Blockstream Green, Blockstream Jade, AQUA), mining colocation (Blockstream Mining), satellite network (Blockstream Satellite), and protocol contributions (Bitcoin research, c-lightning), we are proud to be making global peer-to-peer finance a reality

The research team supports Blockstream’s efforts and the wider Bitcoin ecosystem. The main focus is on signature schemes and scripting languages for the Bitcoin protocol, sidechains and the Lightning Network. Furthermore, Blockstream Research drives key open source projects in the Bitcoin space.

What You’ll Be Doing (Responsibilities):

• Contribute to open source cryptography libraries such as {rust-,}secp256k1{,-zkp} (implement new schemes, review, QA)
• Help with designing, developing and breaking new cryptographic schemes
• Devise and critically evaluate specifications of cryptographic systems, e.g., in the multi-, threshold- and aggregate-signature space.

What We Look For In You (Required Qualifications):

• Experience implementing cryptography
• Care about secure and misuse-resistant designs

Nice To Haves (Preferred Qualifications):

• Knowledge of Rust or C or willingness to learn C89
• Previous academic work on digital signatures, discrete logarithm based cryptography, post-quantum cryptography, zero-knowledge proofs, or other areas of cryptography
• Master's degree or PhD in Computer Science or a related field
• Familiarity with Bitcoin and Layer 2’s at a protocol level
• Familiarity with contributing to open source projects
