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 Smart Contracts team is looking for a seasoned EVM engineer who can contribute to the performance and optimization of the Hedera native services (Java) and the web3 services (JS/TS) that process transaction bytes to transform the network node states and expose network block, transaction, and account data.
You may find yourself doing all of the following:
- Designing, implementing, and innovating compiler and optimization algorithms
- Implementing and enhancing the Java and Node JS-based smart contract services on the Hedera network that expose EVM features
- Contributing to open source code clients that focus on VM state transitions based on contract bytecode with a goal of new feature support and performance improvements
- Contributing to the design and management of EVM state processing parallelization
- 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:
- Master’s degree in Computer Science or a similar field or equivalent work experience
- 7+ years of software development experience
- Experience with distributed open-source application development
- Hotspot JVM or GraalVM experience
- Excellent debugging, critical thinking, and interpersonal skills
- Experience with compilers, parsers, interpreters, and garbage collectors
- Experience with performance, static code, and data-flow analysis
- Expertise in the Java programming language, VM, and its ecosystem of libraries and tools
- Deep knowledge of and experience with an EVM-based blockchain
- Experience writing and debugging smart contracts for an EVM-based ledger
- Experience with web3 tools written in JavaScript or TypeScript
- Experience in a tech or team lead role with the ability to guide engineers up to the Staff level
- 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 high-performance architectural systems and design patterns
- 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:
- Experience with blockchain (e.g., Bitcoin or Ethereum) protocol development is a plus
- EVM Client development
- Familiarity with security principles, cryptographic tools, and libraries
- Experience in developing libraries and platforms for use and deployment by application developers
What is EVM?
EVM stands for Ethereum Virtual Machine, and it is the runtime environment for smart contracts in the Ethereum network
It is a virtual machine that executes code written in the Solidity programming language, which is the language used for writing smart contracts on the Ethereum platform
The EVM is a sandboxed environment, which means that code executed within the EVM is isolated from the rest of the network and cannot interact with it directly
This is important for security reasons, as it prevents malicious code from affecting the rest of the network
When a smart contract is deployed to the Ethereum network, it is compiled into bytecode that can be executed by the EVM
Each node on the network maintains a copy of the EVM, which allows them to execute smart contract code and validate transactions
When a transaction is submitted to the network, the EVM processes it by executing the corresponding smart contract code
The EVM processes the transaction by reading the bytecode, interpreting it, and executing it step by step
The EVM then returns the result of the transaction to the sender, which can include changes to the state of the contract or the network as a whole
The EVM is designed to be Turing-complete, which means that it is capable of performing any computation that can be performed by a computer
This allows for complex smart contracts to be executed on the Ethereum network, including those with conditional logic, loops, and other advanced programming constructs
The EVM is a key component of the Ethereum network, as it allows for the execution of smart contracts in a secure and isolated environment
It is a crucial part of the blockchain infrastructure that enables decentralized applications to be built and run on the Ethereum platform.
