Senior Blockchain Integration Developer (Remote)

=nil; Foundation has been at the forefront of Ethereum scalability solutions since 2018. With a mission to overcome the Ethereum scalability challenge, the team has been working on Ethereum L2 blockchain leveraging zkSharding to enhance scalability through horizontal scaling, modularity, and verifiable security.

Our architecture supports parallel transaction processing across multiple execution shards, each validated by zero-knowledge proofs (ZKPs) and EVM opcode compatibility. To develop dApps on =nil;, we use Solidity with a set of precompiles that enable multi-currency support and asynchronous communication. Interoperability among shards is seamlessly maintained through a native cross-shard communication protocol, enabling efficient and secure interactions within the network

We are looking for someone to join our Integration Team. The team key responsibilities are:Integration: Build and integrate tools like explorers, wallets, plugins, and extensions, ensuring a seamless user experience with =nil;Decentralized Application Development: Architect and develop the first dApps on top of =nil;, utilizing sharded architecture and multi-currency features. This involves exploring innovative project ideas or adapting existing dApps like Uniswap V2 to the =nil; ecosystem, pushing the boundaries of decentralized technology

Responsibilities:Work on internal integrations to support =nil;, such as developing tools like the hardhat-plugin, block explorer, in-browser IDE, Block Indexer, and more. =nil; protocol is written in Go, and most integrations utilize TypeScript. Examples of existing integrations include:CLI: Command-line interface for interacting with =nil; (written in Go)Hardhat-plugin: Adapts requests and responses to match =nil; RPC and unique features (TypeScript)Block Explorer: A tool for viewing block and message data (TypeScript)

Develop and Design the first cross-shard dApps on top of =nil;, leveraging the sharding and multi-currency features. Examples include:Adapting Uniswap V2 to =nil; by adding multi-currency support and modifying the architecture to distribute load across multiple shards.Designing the architecture for an orderbook DEX to operate efficiently on a sharded blockchain.

QualificationsAt least 5 years of engineering background with the ability to adapt to various programming languages and tech stacks as required by different projects (experience with Go, TypeScript, or Solidity is a plus)Willingness to learn and work with Web3 protocols and blockchain technologies, even if prior experience is limitedAbility to design and implement scalable and secure systems in a decentralized environmentIndependent and proactive, with the ability to take ownership of projects from inception to completionProficiency in English (B2+), both written and spoken, to effectively collaborate with international teams
