Venture Builder
Improbable is a Venture Builder. We are working with leaders to create businesses in AI transformation, the metaverse and web3. We both create businesses from scratch and invest in existing businesses. Our central services teams work with ventures to help them achieve success; including early stage prototyping and initial product development where this role sits.
Your Mission
As a Principal web3 Solidity Engineer at Improbable, you will work with web3 Ventures to help them get to market faster. You will work with their leadership team to design, prototype, and launch initial versions of their dApps. This is a hands-on, strategic role where you will collaborate with executives, working all the way from identifying customer problems to shipping real dApps used in the community.
What You’ll Be Doing
- Architect, build, launch, and maintain Dapps - from concept to being used by the community
- Build on-chain logic in smart contracts, and connect them to web front-ends to be used by crypto natives and novices
- Work with business leads to define the product roadmap, help set the vision and strategy for the venture, act as a sounding board for venture leadership
- Work closely with the Somnia Blockchain team and provide product feedback to their developers
Why You’re Made For This
We are seeking an experienced Web3 Engineer with experience on EVM-based smart contracts in Solidity, Web3 JS/TS libraries for contract interactions with frontend and backend systems, and experience with The Graph.
You have strong hands-on skills with the blockchain development framework Foundry.
You’ve shipped web apps built with TypeScript (preferably React, Next.js) and used wagmi hooks for smart contract integrations.
You have a deep understanding of blockchain architecture, token standards (ERC-20, ERC-721, ERC-1155), and non-standard versions (e.g., USDC).
Knowledge of Solidity best practices and common security vulnerabilities.
You thrive when solving complex, ambiguous problems and enjoy working across disciplines to find the best solutions.
You are passionate about the web3 community.
Optional Skills
Experience with The Graph protocol for creating Subgraphs, designing smart contracts for optimal indexability, DeFi protocols like Uniswap and AAVE, Solidity fuzz testing, Slither, Mithril, and Hardhat testing framework are helpful but not essential.
We welcome applications from candidates with valuable experience, even if they do not meet every listed requirement. If you identify with the team and mission, please apply.
