Blockchain Engineer




C# Java Python Kotlin intermediate

What are we all about?

We are a team of builders and researchers on a mission to empower enterprises and developers worldwide to access and build on decentralized systems.

Our expertise covers several domains: Ethereum and Starknet protocol engineering, layer-2, cryptography research, protocol research, decentralized finance (DeFi), security auditing, formal verification, real-time monitoring, smart contract development, and dapps and enterprise engineering.

Working to solve some of the most challenging problems in the blockchain space, we frequently collaborate with, such as Ethereum Foundation, Starknet Foundation, Gnosis Chain, Flashbots, Forta Protocol, Lido, EigenLayer, Open Zeppelin, RISCZero, Aleph Zero, and many more.

Today, there are nearly 200 of us working remotely from over 45+ countries.

Are you the one?

We are looking for a passionate and skilled engineer to join our highly dynamic team.

You will be developing blockchain-based solutions that span across a wide spectrum of the web3 ecosystem, from protocol level engineering and smart contracts development to DApps and Enterprise/Financial applications that integrate with or are built on blockchain infrastructure.

This is a remote-first role. You will be working with a globally distributed team of talented engineers and researchers, as well as many leading industry partners.

You should be proficient in at least one or more general programming languages (refer to the skills section for details), as well as Smart Contract development, primarily Solidity. A deep understanding of the Ethereum blockchain, strong general engineering skills, and a firm grasp of computer science fundamentals are required. The ideal candidate would be a robust problem-solver with excellent attention to detail and effective communication skills. Familiarity with non-EVM blockchains, the DeFi landscape, and traditional finance would be advantageous.

Responsibilities include, but not limited to:

  • Work on full-stack engineering solutions that integrate with or built on top of blockchains.
  • Design and build applications on various blockchains
  • Develop, test, and deploy secure smart contracts
  • Debug and optimize smart contracts
  • Extract and process data from the blockchain
  • Develop scripts & tools to automate or improve blockchain interactions
  • Collaborate with other engineers and teams, both internally and externally
  • Stay updated with new developments and technology in the blockchain space

Technical Skills:

  • Excellent programming skills in one or more of the following programming languages: C#, Go, TS/JS, Solidity, Rust, Python, Java, Kotlin, but will also consider other tech stacks.
  • Proficient in a smart contract programming language (eg. Solidity, Cairo, MOVE) with extensive experience in developing complex smart contracts. Familiar with toolings such as Foundry, Hardhat or Remix.
  • Ability to implement efficient algorithms and design complex data structures
  • Understanding of good software architecture and engineering process
  • Ability to write clean, testable, and maintainable code without over-engineering
  • Deep understanding of Ethereum blockchain architecture
  • Understanding of the DeFi landscape, such as lending protocols, AMMs, Perps and stablecoins
  • Experience in developing off-chain applications that integrate with web3 protocols, using libraries such as Web3.js and ethers.js.
  • Strong computer science background

Other Competencies:

  • You need to be a self-starter, with the curiosity and drive to continuously improve.
  • Excellent problem-solving and analytical skills, with attention to detail
  • Strong written and verbal communication and collaboration skills
  • Proficiency in English

Nice to have:

  • Knowledge in Traditional Finance, and the intersection between traditional finance and blockchain, such as Tokenisation.
  • Experience with layer-2 solutions like Starknet, Optimism, zkSync, and Arbitrum
  • Familiarity with blockchain data analytics tools like Dune and Nansen
  • Knowledge of cryptographic primitives like hashing and signature schemes
  • Familiarity with formal verification methods for smart contracts
  • Experience in front-end development with frameworks like React or Angular
  • Familiarity with smart contracts auditing tooling/techniques (e.g Fuzzing, Symbolic execution, Static and Dynamic Analysis)
  • Infrastructure / DevOps experience (eg. setup private networks)
  • Ethereum core development experience.
