About Aztec At Aztec, our goal is to take the original promise of Ethereum–a decentralized and verifiable world computer–and expand its capability immensely by making it fully encrypted. In the current public blockchain paradigm, users and entities unknowingly broadcast data in the public, compromising privacy and security to get trustlessness. Not only are unencrypted blockchains inherently privacy-exposing, they require significant redundancy to compute and verify the legitimacy of transactions. Implementing scalable encryption in a public blockchain paradigm requires cutting-edge math and engineering. Thankfully, our team of scientists and engineers invented Plonk, the industry-standard zkSNARK, and Noir, the universal language of zero knowledge. Now, we’re building a first of its kind public-private encrypted blockchain: Ethereum, encrypted. And it’s now time to bring it to market. We’ve raised $125 million from industry-leading investors including a16z crypto,...

Company Overview:   At Risc Zero, we are dedicated to pushing the boundaries of the digital world. Our team, composed of forward-thinking technologists, curious hackers, and zealous visionaries, is on a quest to forge a more secure, all-embracing internet. We have made strides in the blockchain field by pioneering the world's first zero-knowledge virtual machine, forming the foundation for executing arbitrary code as a zero-knowledge proof. Leveraging a ZK Coprocessor to optimize or enhance on-chain applications, we have shaped a distinct offering - the Risc Zero ZK Coprocessor, featuring zkVM, Bonsai, and ETH Relay. Our current endeavor involves crafting a comprehensive ecosystem around this revolutionary technology. To ensure effective collaboration and seamless communication across our global team, all candidates must be available to overlap with the Pacific Standard Time (PST) zone for at least 3 hours during regular business hours. This requirement is essential...

Role Summary As a cryptographic software engineer at Ulvetanna, you will contribute to internal and open-source zk-SNARK proving codebases, analyze their performance, and propose and implement optimizations. Tasks may include to modifying and refactoring the codebases to utilize hardware coprocessors, reading and implementing zero-knowledge cryptography research, reverse engineering high-level algorithms from open-source software and smart contracts, and designing or analyzing arithmetic constraint systems for verifiable programs. Team members work closely with the FPGA engineers to specify algorithms implemented in hardware, and with the systems software engineers to interface efficiently with hardware acceleration units. Necessary Qualifications A deep passion for technology, software development, and secure computing Demonstrated ability to deliver software projects from inception to completion Understanding of algorithm design and computer architecture...
