Backend Node.js Developer

Remote

Full-time

Vacancy Description

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

What We Offer

Competitive compensation

Social package (24 working days of annual leave and 5 paid sick days)

Flexible working hours

Challenging projects in diverse business domains and a variety of tech stacks

Personal development and professional growth opportunities

Work with talented, ambitious and family-feel team

Educational possibilities: corporate courses, knowledge hubs, and in-house English classes

Compensation for your professional certification & support for your learning activities

Opportunity to choose IT equipment you like

Corporate social responsibility
