Cryptography lead We need somebody with a strong background in cryptography to lead the development of our identity chain and core crypto stack. Ideal background: Experience with zero-knowledge crypto: zk-SNARKs, proof circuits Understanding of E2E encryption as applied to consumer products eg. Signal Familiarity with cloud security concepts like vTPMs, HSMs, attestation Knowledgeable about enterprise key management solutions Ideally some background in C++

Overview Blockchains are not private enough for safe use by citizens, corporations, or dissidents. Heliax is looking for a research cryptographer interested in fully-homomorphic encryption protocols and their application to distributed ledger technology to work with us to design, evaluate, and implement FHE constructions, then put this cryptography into practice in order to realise privacy and scalability capabilities required by the next generation of blockchain networks. This role offers the chance to work closely with a small team on compelling cross-disciplinary problems in theoretical computer science, cryptography, game theory, economics, and systems design, and enjoy a high degree of independence in working conditions and task prioritization. Responsibilities -Evaluate and analyze existing FHE protocols for security, expressivity, and performance, monitor the state of the research field for compelling new theoretical advances, and conduct original exploratory research...

Overview Blockchains do not scale to a global user-base of seven billion people. Rust engineering at Heliax focuses on building, extending, and maintaining decentralized, permissionless, and censorship-resistant protocols. We are looking for experienced Rust developers that are interested in applying novel research to create high-quality open-source technology and solve outstanding problems in the blockchain space. As a member of the core protocol engineering team, you will be working on distributed ledger technology implemented in Rust, all the way up and down the stack from the P2P layer to consensus algorithms, smart contract systems, proof-of-stake incentive mechanisms, privacy-enhancing cryptographic components, and on-chain governance procedures. This role offers the chance to work closely on compelling cross-disciplinary problems in computer science, systems engineering, cryptography, and economics, and enjoy a high degree of independence in working conditions and...

As an early team member on a small team, you’ll have a meaningful stake in what we build and how we operate. What will you be doing? Exceptional software engineering skills, ability to refactor and optimize code Deep understanding of encryption technologies and how to use them to build secure systems Produce high quality, Typescript, test driven code Create processes to automate building libraries with complex dependency requirements Produce high quality documentation for other developers Experience designing easy to use API’s for other developers to consume Design, implement, test, and audit protocol code upgrades and additions Defining and setting up a strong foundation for long term maintainability of large scale design systems Experience using and designing NoSQL databases Work well...

About us OpenZeppelin is a leading cybersecurity company that provides security products to build, automate, and operate decentralized applications. With a mission to protect the open economy, our team created the most popular open source library for smart contract development with over 4 million downloads. Our unique expertise subsequently allowed us to uncover major security vulnerabilities for the Ethereum Foundation,  MakerDAO, and Facebook’s Libra, and conduct security audits for many top blockchain companies including Coinbase, Brave, Compound, Aave, and Augur.  Building on this experience, we recently launched a platform to help teams automate their Ethereum operations and securely ship products faster: OpenZeppelin Defender.  With the success of our products, security audit work, and open source educational efforts, we are setting industry standards for building secure systems in a fast-growing industry that is creating an open financial system for the...

Who We Are:   Manta is the leading on-chain privacy platform for Polkadot and more. Our mission is to provide privacy for all crypto assets and decentralized finance (DeFi) activities. We are building from first principles, applying cutting-edge cryptographic constructions such as zkSNARKs to implement our design from scratch. We are supported by leading crypto investors including Polychain Capital and many more and grants from Web3 Foundation.    We have two actively developing products right now: MantaPay: the first protocol providing plug and play on-chain privatization of Polkadot ecosystem assets. MantaSwap: the first practical privacy preserving decentralized exchange with a rigorous cryptographic guarantee.    If you are excited about building privacy-preserving solutions using zero-knowledge proofs, building blockchain applications, or learning about Polkadot ecosystems, then we want to hear from you.
