Founding Fullstack Engineer

💻 Software Development🟣 Senior

Job description

About Us

We are ZetaChain, Our mission is to build a Universal Blockchain with native access to any blockchain, making crypto as accessible, diverse, and connected as the internet. Build apps that interact with networks and tokens natively without the need for wrapping or bridging. Or add a smart contract layer to chains, such as Bitcoin.

Now we are onto something new: We are building a new dApps team and we’re building Soul — an AI-powered Web3 app for fortune-telling, identity, and social discovery — and other upcoming consumer-facing products in the blockchain space.

About the Role

You’ll be our first in-house engineer and the technical backbone of our Web3 apps (starting with Soul). You’ll own end-to-end development, from blockchain integrations to backend and frontend, while setting the foundation for our engineering team.

Responsibilities

  • Lead technical architecture and development of Soul + upcoming apps.

  • Build blockchain integrations: wallet connection, calling smart contracts, data flows.

  • Develop across stack: frontend (React/Next.js), backend (Node.js), infra (Kubernetes/GCP).

  • Establish engineering best practices

  • Mentor future hires.

Requirements

  • 5+ years of fullstack development.

  • Strong blockchain/Web3 experience (Solidity, smart contracts, EVM chains).

  • Familiarity with smart contracts is required but you do not write smart contracts as part of this role

  • Proven track record in consumer apps or startups.

  • Startup mindset: hands-on, independent, fast-moving.

Growth & Culture

  • Shape the engineering vision as our first founding engineer.

  • Work closely with the founder, with exposure to product, design, and strategy.

  • Remote-first culture with async-friendly communication.

  • Opportunity to grow into Head of Engineering as we scale.

  • We’d love to offer token share benefits, so you grow with the company’s success.
