Protofire as great enthusiasts and active contributors to the open-source blockchain communities, we help builders and providers of decentralized infrastructure, protocols, and applications, bootstrap the demand and supply sides of their markets and accelerate mass adoption.
We help startups with protocol & smart contract engineering, high-performance trusted data feeds (oracles), and awesome developer tools (SDKs/APIs).
Since we started in 2016 we’ve had a chance to contribute to the development of many top projects in the blockchain ecosystem, including Maker, Chainlink, Tezos, Gnosis, Kyber Network, The Graph, Filecoin, Synthetix, Avalanche, and more. Apart from that, we are running one of the biggest indexer nodes in the Graph Network, participating as bridge relayers and validators helping projects and networks to further decentralize their infrastructure.
We are now looking to hire a cross-disciplinary team to help Protofire scale. As such, we’re looking for a Solidity Developer who’s had extensive experience writing, testing, deploying, and auditing smart contract code and who is up to date on the current developments in Solidity.
Besides knowing Solidity, we’d love to hear your informed opinion on the latest developer tooling, adhere to industry best practices, and follow the latest vulnerabilities and hacks in the Ethereum smart contract space with interest.
How you will make an impact:
- Produce high quality, performant, and well-tested Solidity code
- You’ll be working with advanced smart contracts, working on new features for the protocols, and creating new technical DeFi primitives
- Conducting technical due diligence and understanding dynamics/tradeoffs between different blockchain protocols
- Perform smart contract audits and identify vulnerabilities
- Work closely with the product team towards building out a DeFi application Integrating front ends with smart contract code
- Achieve comprehensive unit and integration test coverage
- Design and ideation of new functionality
What you need to succeed:
- 5+ years of experience in another programming stack or language
- 1+ years of Solidity smart contract development experience
- Understanding of Javascript Ethereum SDK’s (web3.js, ethers.js)
- Experience deploying Dapps or smart contracts on to Ethereum
- Smart contract dev tools/frameworks – hardhat and truffle
- Hands-on experience conducting smart contract audits, including identifying vulnerabilities, documenting findings, and providing recommendations for remediation.
- Familiarity with common attack vectors and auditing methodologies (e.g. reentrancy, front-running, integer overflows, gas optimization, etc.)
- CI/CD setup experience
- Deep understanding of the Ethereum Virtual Machine and the broad decentralized finance ecosystem
- Problem-solving attitude, ability to act autonomously, participate in discussions, and actively propose solutions.
- Excellent communication skills – You know how to work in teams, give and receive feedback, identify bottlenecks.
- A desire to keep up with blockchain technology trends and a real interest in decentralization
