Requirements

  • 6–8+ years of hands-on full-stack engineering experience, with deep roots in both frontend and backend.
  • At least 4 years steeped in web3—building with blockchain protocols, smart contracts, and decentralized tooling.
  • Mastery of modern JS/TS frameworks like React, Next.js, or Vue.js—your frontend skills should be second nature.
  • Deep knowledge of databases, both SQL (Postgres) and NoSQL (Mongo, Firestore), and when to use which.
  • Backend prowess with Node.js, REST APIs, and microservice architectures; experience with containers (Docker, Kubernetes) is a must.
  • A solid grasp of Intent-Based Bridging and Solver Networks—bonus points if you’ve worked on them in production.
  • Ability to read, understand, and integrate Solidity contracts into real-world applications.
  • Proven success working in fast-moving, agile environments and collaborating across multiple teams to ship scalable systems.

    • Responsibilities

  • Architect and build full-stack applications that talk to smart contracts and EVM chains—delivering snappy, intuitive web3 experiences.
  • Take the reins on system design for dApps, multi-chain SDKs, and smart contract indexers spanning multiple Layer 2 networks.
  • Champion best practices in code quality, scalability, and performance while tackling tech debt like a boss.
  • Mentor a dynamic team of engineers and collaborate across disciplines—from Product to Security—to deliver resilient, future-ready solutions.
  • Contribute to planning, sizing, and de-risking of complex projects with many moving parts.
  • Keep a pulse on performance, security, and observability to ensure smooth sailing in production.
