Are you the one?
If you've envisioned yourself at the forefront of AI and ZK innovation, then Nethermind offers the perfect opportunity to transform that vision into reality.
Nethermind is a Blockchain Research and Software Engineering company. We empower enterprises and developers worldwide to access and build on the decentralized web. Our work touches every part of the blockchain ecosystem - from fundamental cryptography research to application-layer protocol development.
We are currently seeking talented and passionate Cairo Developers to join our growing AI and ZK group. Successful candidates will research, design, develop and optimize protocols and applications fundamental to the advancement of Ethereum, Starknet and Web3.
Responsibilities:
- Design and implement scalable and secure smart contracts, decentralized applications (dApps), and ZK protocols using the Cairo programming language.
- Collaborate closely with cross-functional teams, including cryptographers, mathematicians, and blockchain engineers, to develop and integrate advanced cryptographic primitives and algorithms.
- Optimize Cairo code for performance, gas efficiency, and security, ensuring the scalability and cost-effectiveness of our solutions.
- Contribute to the development and enhancement of Cairo tooling, compilers, and documentation to improve the developer experience.
- Stay up-to-date with the latest advancements in blockchain technology, cryptography, and the Ethereum ecosystem, actively participating in relevant communities and conferences.
Skills:
- Proven experience and proficiency in developing smart contracts using Cairo.
- Strong understanding of cryptography, zero-knowledge proofs, and their applications in blockchain technology.
- Familiarity with the Ethereum ecosystem, including EVM, Layer 2 scaling solutions, and Web3 technologies.
- Excellent problem-solving, analytical, and critical thinking skills.
- Strong communication and collaboration abilities, with the ability to work effectively in a team environment.
- Passion for decentralized technologies, cryptography, and the potential of Web3 to revolutionize various industries.
Nice to have:
- Familiarity with zk proof systems (ZK-STARK, ZK-SNARKs)
- Cryptography background
- Mathematics Background
- Having activity on GitHub is a significant advantage (please include links to projects or PRs that you have submitted to external projects)
What is Zero-knowledge?
Zero-knowledge is a concept in cryptography that allows two parties to exchange information without revealing any additional information beyond what is necessary to prove a particular fact
In other words, zero-knowledge is a way of proving something without actually revealing any details about the proof
Here are some examples of zero-knowledge:
- Password authentication: When you enter your password to log into an online account, the server doesn't actually know your password. Instead, it checks to see if the hash of your password matches the stored hash in its database. This is a form of zero-knowledge because the server doesn't know your actual password, just the hash that proves you know the correct password.
- Sudoku puzzles: Suppose you want to prove to someone that you've solved a particularly difficult Sudoku puzzle. You could do this by providing them with the completed puzzle, but that would reveal how you solved it. Instead, you could use a zero-knowledge proof where you demonstrate that you know the solution without actually revealing the solution itself.
- Bitcoin transactions: In a Bitcoin transaction, you prove that you have ownership of a certain amount of Bitcoin without revealing your private key. This is done using a zero-knowledge proof called a Schnorr signature, which allows you to prove ownership of a specific transaction output without revealing the private key associated with that output.
- Secure messaging: In a secure messaging app, you can prove to your contacts that you have access to a shared secret without revealing the secret itself. This is done using a zero-knowledge proof, which allows you to prove that you have access to the secret without actually revealing what the secret is.
