Senior Solidity/Smart Contract Engineer

WE ARE: StartupSoft connects top Ukrainian engineers with world-class startups from Silicon Valley and EU. Our developers work directly on the product as an integral part of the startup team.

PROJECT:

Leading Web3 governance software that combines contract and client work to deliver software that empowers the creative action and participation of tens of thousands and delegates and community members across the world’s biggest DAOs.

Their vision is to reduce the barriers to human coordination and make those problems as efficient and effective as possible. They are currently working with some of the world’s biggest and most influential DAOs: Uniswap, ENS, Optimism, Nouns and more. Each day, they build better and better software for these communities to coordinate people and resources to empower collective, distributed actions in our world. Over the coming years, they will build out their own governor and protocol that will take all that they have learned and continue to learn from working with these great DAOs and bring it to the mainstream.

TEAM: СЕО, CTO, Head of Engineering, 15 ppl at customer service, 10 engineers;

PROJECT STACK: Solidity, Foundry, Web3.

PROJECT STAGE: seed, live product.

REQUIREMENTS:

• Passion for or curiosity about Web3 governance, with the ability to discuss its challenges and potential.
• Understanding of the Web3 data stack — how data moves onto the EVM and into applications efficiently.
• Familiarity with key Web3 protocols like Lido, Uniswap, and ERC-721/1155, with the ability to explain their design patterns.
• Experience optimizing smart contracts to reduce gas costs while maintaining quality.
• Knowledge of L2 solutions (e.g., Optimism) or a strong interest in learning how they operate.
• Enthusiasm for open-source development — be ready to share code or discuss favorite projects.
• Strong Solidity development skills and experience with smart contract creation.
• Proficiency with the Foundry toolchain.

RESPONSIBILITIES:

• Develop and maintain smart contracts using Solidity.
• Work specifically with the Foundry toolchain (mandatory).
• Reviewing existing Governance and DAO contracts of prospective customers and making suggestions of how they could improve the design of their governor and estimating the time and cost of each.
• Working with our auditors to address issues and designs with our existing protocol code and smart contracts.
• Working with the team to brainstorm and contribute to our protocol’s whitepaper and design documents as we build out the future of collective, creative human collaboration.
• Working on contract upgrades for existing DAOs using the ERC-20, ERC-721 and ERC-1155 protocols.
• Working on building our own deployer and upgrade contracts for our new customers that don’t have existing governance solutions.
• Working with our engineering team to make sure that the contracts you are writing are being indexed and called properly and that our application is working as best as can be.
• Most importantly, thinking creatively and outside the box when it comes to pushing the envelope on the design and engineering of innovative Governance and voting modules to make the experience of collective creation and human collaboration better for new and existing DAOs.

YOU WILL GET:

• Competitive financial reward and other social benefits;
