About Hashgraph
Hashgraph is a fast-growing software company committed to supporting, developing and servicing Hedera, an open source, proof-of-stake platform. Hedera is EVM-compatible and has been specifically built to meet the needs of enterprise and Web3 applications, which require speed, security, stability and sustainability. Hedera’s public network is governed by industry-leading organizations, spanning 11 sectors and 14 regions who oversee the development and direction of the decentralized platform.
About the role The EVM Developer Experience team is looking for a seasoned web3 engineer who can contribute to the development of the Hedera services and web3 and Ethereum community tools that enable the processing of smart contract transactions across the network.
You may find yourself doing all of the following
Staying connected with the EVM ecosystem, bringing vital learnings, discussions, and applicable explorations on Hedera back to the team to improve EVM DevEx
Implementing and enhancing the JSON Rpc Relay (Js/Ts) to enable seamless EVM transactions submission to the network
Maintaining and evolve community tools like blockexplorer, verification and data gathering services, that hashgraph deploys for community servicing
Implementing examples, how-tos, and documentation that showcase web3 tool usage, and EIP and Hedera functionalities
Designing, developing, and maintaining server-side logic for back-end solutions with public APIs involving TypeScript, SQL, data ingestion, REST, GraphQL, and Web Sockets
Applying web3 knowledge of Solidity and life cycle of an EVM transaction
Writing efficient, reusable, and reliable code to optimize for maximum speed, scalability, and system efficiency
Exploring and unblocking web3 tool and dApp integration capabilities on Hedera, ensuring developers can continue to use their familiar tools when migrating to Hedera from other EVM chains
Spending 80% of your time designing, coding, and testing
Qualification Requirements
Master’s degree in Computer Science or a similar field or equivalent work experience
7+ years of software development experience
4+ years of blockchain development experience
Proficiency in JS/TS programming language and its ecosystem of libraries
Node.js backend development experience
Familiarity with high-performance architectural systems and design patterns
Knowledge of the blockchain technology ecosystem, particularly EVM
Experience with smart-contract development with Solidity/Vyper, HardHat, Foundry, Web3.js / Ethers.js frameworks, JavaScript/TypeScript
Experience writing secure, efficient, and gas-optimized smart contracts for decentralized applications (dApps) on EVM-compatible networks
Experience with wallet integrations (MetaMask, WalletConnect, etc.), and tools and libraries for connecting web3 applications with users' wallets
Understanding of Ethereum ecosystem ERC20s, ERC721s, ERC1155s, on-chain and off-chain
Ethereum Json RPC specification knowledge
Experience with distributed open-source application development
Excellent debugging, critical thinking, and interpersonal skills
Familiarity with test-driven software development processes and continuous integration tools and systems
Other skills that are great to bring with you but that we can help you develop
Knowledge of the Hedera network
Experience with web3 tools that support indexing, verification, and transaction management, such as TheGraph, Sourcify, or Blockscout
Strong understanding of RESTful API design and development
Strong grasp of Computer Science fundamentals including concurrency, performance optimization, and reusability
Strong engineering principles and processes aimed at developing simple, modular, testable, and high-quality code
Familiarity with security principles, cryptographic tools, and libraries
Kubernetes, Helm, Grafana, and GCP experience
