https://electronlabs.org/">Electron Labs is building a new protocol to make various blockchains interoperable. Our goal is to enable cross-chain contracts to connect with each other in the same way as same-chain contracts connect i.e., via function calls. We have developed a new in-house tech called https://garvitgoel.medium.com/what-is-bdlc-and-how-it-works-5716fbbacde8">Bi-Directional Light Client that allows a smart contract to independently verify whether the cross-chain transactions submitted to it are valid. We further use ZK-SNARKS to reduce the gas cost of running the light client on-chain.

Desired Qualifications

1. A good grasp of blockchain fundamentals, various consensus algorithms, and detailed knowledge of at least one major blockchain.
2. Previous work (demonstrable) in blockchain technology, web3, or protocol development
3. In-depth understanding of Number Theory and Cryptography. Knowledge of Cryptographic Algorithms and zero-knowledge proofs are highly preferred.
4. Superior mathematics and problem-solving skills, excellent pattern recognition, passion for solving puzzles.
5. Proficiency in one of the following languages: Go-lang, Rust, is highly preferred. Working knowledge of Solidity, Javascript, Python, or similar scripting languages puts you in front of our list
6. Grounded research skills and an ability to absorb documentation quickly
7. Strong background in Computer Science. Knowledgeable in Algorithms and Data Structures.

Roles and Responsibilities

1. You will be assigned one blockchain (Ethereum /Polygon /NEAR /tendermint /Polkadot/Aleo). You will be required to implement the light client of this blockchain in https://docs.circom.io/">Circom language (Domain Specific Language for ZK-SNARKS).
2. Write go-lang based networking relayers that enable communication between blockchains and zk-provers.
3. Maintain relayer and zk-prover infrastructure (cloud machine and codebase)
4. Write kickass documentation.
