Overview:

Improbable is a Venture Builder and a pioneering technology company developing next-generation networked and digital infrastructure for the web3 economy. 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.

Over the past decade, the company has evolved into a global leader in venture building, decentralised technology, digital assets, and blockchain-enabled infrastructure—empowering creators, brands, and communities to build and scale the next era of digital experiences.

Your Mission:

Somnia is building next-generation blockchain infrastructure. We are seeking a Senior Full Stack Web3 Engineer to define, architect, and implement foundational protocol principles of the Somnia blockchain. This is a senior, hands-on engineering role for an individual who has previously shipped production-grade blockchain protocols incorporating advanced AI/ML components and is comfortable operating at the intersection of research, architecture, and execution.

You will play a critical role in shaping the core protocol, influencing long-term technical direction, and ensuring Somnia’s blockchain is secure, scalable, and fit for real-world adoption, specifically exploring how decentralized AI models can enhance the network. We are seeking an experienced Web3 Engineer with experience on EVM based smart contracts on Solidity, Web3 JS/TS libraries to perform contract interactions with frontend and backend systems as well as experience with creating and interacting with The Graph.

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
• Working closely with the Somnia Blockchain and providing product feedback to their team of developers

Why You’re Made For This:

• You’ve shipped multiple production-grade dApps built using Solidity.
• You have strong hands-on skills with the blockchain development framework Foundry
• You’ve shipped webapps 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-compliant versions of the standard (e.g. USDC)
• Knowledge of Solidity foundational best practices and most 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.

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