About The Role:
The Smart Contracts team is looking for a seasoned engineer who can contribute to the development of the Hedera services in both the Java and the web3 APIs in JS/TS that process smart contract transactions across the network submitted using varied web3 tools.
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 Java-based smart contract services on the Hedera network that parse byte code and process transactions submitted to the network via an EVM client
- 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 EVM transactions life cycle
- 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 devs can continue to use their familiar tools when migrating to Hedera from other EVM chains
- Continuously discovering, evaluating, and implementing new technologies to maximize development efficiency and effectiveness
- Developing various aspects of the Hedera Hashgraph Distributed Ledger Ecosystem
- Being a strong and proficient hands-on programmer
- Spending 80% of your time designing, coding, and testing
Qualification Requirements:
- Experience with distributed open-source application development
- Excellent debugging, critical thinking, and interpersonal skills
- Knowledge of the blockchain technology ecosystem, particularly the EVM
- Expertise in the Java and JS/TS programming language and its ecosystem of libraries and tools
- Experience with smart-contract development with Solidity/Vyper, Foundry, Web3.js / Ethers.js frameworks, JavaScript/TypeScript
- Experience with Ethereum Development Suites (e.g., Harhat, Foundry, Truffle, Ganache, Tenderly)
- Experience writing secure, efficient, and gas-optimized smart contracts for decentralized applications (DApps) on EVM-compatible networks
- Understanding of Ethereum ecosystem ERC20s, ERC721s, ERC1155s, on-chain and off-chain
- Experience with Wallet integrations (MetaMask, WalletConnect, etc.): Tools and libraries for connecting Web3 applications with users' cryptocurrency wallets
- Strong understanding of RESTful API design and development
- Familiarity with test-driven software development processes and continuous integration tools and systems
- Experience with web3 tools that support development, indexing, and transaction management, such as TheGraph
- 7+ years of software development experience
- Master’s degree in Computer Science or a similar field or equivalent work experience
Other skills that are great to bring with you but that we can help you develop:
- Knowledge of the Hedera network
- Deep knowledge of and experience with the Java VM, covering its strengths and weaknesses
- 5+ years of Java experience
- Deep knowledge of and 5+ years of experience with Node JS, covering its strengths and weaknesses
- 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
- Familiarity with high-performance architectural systems and design patterns
What does a Java developer in web3 do?
A Java developer in web3 would likely be focused on developing applications that use the Java programming language in the context of the web3 technology stack
Web3 is a collective term used to refer to the next generation of decentralized, blockchain-based technologies that are aimed at creating a more open and secure internet
In this context, a Java developer would be responsible for writing code that interacts with web3 technologies, such as decentralized applications (DApps) and smart contracts, to create new tools and services that run on the blockchain
This could involve working with cutting-edge technologies such as Ethereum, which is a popular blockchain platform that uses the Java programming language, as well as other web3 technologies and frameworks.
