Your Mission

As a Principal web3 Solidity Engineer at Improbable, you will:

• Work with web3 Ventures to help them get to market faster.
• Collaborate with leadership teams to design, prototype, and launch initial versions of their dApps.
• Engage in a hands-on, strategic role, 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 community usage.
• Build on-chain logic in smart contracts and connect them to web front-ends for both crypto natives and novices.
• Work with business leads to define the product roadmap and set the vision and strategy for the venture.
• Act as a sounding board for venture leadership.
• Collaborate closely with the Somnia Blockchain team, providing product feedback.

Why You’re Made For This

We are seeking an experienced Web3 Engineer with:

• Experience in EVM-based smart contracts using Solidity and Web3 JS/TS libraries for contract interactions with frontend and backend systems.
• A track record of shipping multiple production-grade dApps built using Solidity.
• Strong hands-on skills with the blockchain development framework Foundry.
• Experience in building web apps with TypeScript (preferably React, Next.js) and using wagmi hooks for smart contract integrations.
• A deep understanding of blockchain architecture, token standards (ERC-20, ERC-721, ERC-1155), and non-compliant versions of the standard (e.g., USDC).
• Knowledge of Solidity foundational best practices and common security vulnerabilities.
• A passion for solving complex, ambiguous problems and working across disciplines to find the best solutions.
• A strong interest in the web3 community.

Optional Skills

The following technical experience is helpful but not essential:

• Experience using The Graph protocol to create Subgraphs on smart contracts and/or designing smart contracts for optimal indexability.
• Experience in the DeFi ecosystem, particularly with swapping protocols (e.g., UniswapV2 or V3) and/or lending protocols (e.g., AAVE).
• Awareness of Solidity fuzz testing, Slither, and/or Mithril.
• Familiarity with the Hardhat testing framework.

While we think the above experience could be important, we’re keen to hear from people who believe they have valuable experience to bring to the role. If you identify with the team and mission but do not meet all of our requirements, please still apply.
