We are IdeaSoft’s Ethereum-focused R&D Department – a small, fast, and relentless team building new Web3 applications from zero to one. We ship fast, break things, validate ideas, and pivot quickly.
Now, we are looking for a Backend Developer (Node.js) who thrives in chaos, doesn’t need Jira to get things done, and loves building new products in the Ethereum ecosystem.
Bonus Points
You have shipped a Web3 product before (even a hackathon POC counts)
Familiar with Uniswap V4, Farcaster, AI agents, session keys, or anything cutting-edge in Ethereum
You’ve contributed to open source or written technical articles
Requirements:
Solid experience with Node.js, TypeScript, and building REST/GraphQL APIs (usually NestJS)
Comfortable with Ethereum/Web3 libraries (ethers.js, viem, etc.)
Experience with smart contract integrations, event listening, or building indexers is a big plus
You’re fast. We don’t mean reckless. We mean you prefer to ship something in 2 days rather than perfect it for 2 weeks
You can work without Jira, PMs, or daily standups. You take responsibility and move
You’re resourceful, scrappy, and can Google your way through tough problems
Responsibilities:
Build backend logic for new Ethereum-based applications (Mini apps, DeFi, AI agents, etc.)
Integrate on-chain and off-chain components: smart contracts, indexers, APIs, bots
Write fast and functional prototypes, iterate based on feedback, and push to production when needed
Deploy and manage infrastructure (we use Docker, PostgreSQL, Redis, etc.)
Own what you build. If something breaks, you fix it
