  • 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

  • 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:
