We are looking for an experienced Senior Full-stack Web3 Engineer to join our team and contribute to building modern blockchain-powered applications. You will work across the full technology stack — from frontend interfaces and backend services to on-chain integrations — delivering scalable and secure Web3 products used by real users.

 

This role is ideal for engineers who enjoy owning features end-to-end, working with decentralized systems, and solving complex product challenges in Web3 environments such as DeFi platforms, wallets, or blockchain-based services.

 

Requirements

 

  • 5–7+ years of professional experience as a Full-stack Engineer, including hands-on production experience with Web3 applications.
  • Strong experience building dApps and Web3 integrations, including wallet connectivity, blockchain RPC interaction, indexing, and transaction processing.
  • Understanding of DeFi primitives such as DEXs, swaps, lending, liquidity pools, and trading mechanisms.
  • Experience with modern frontend development using TypeScript, React, Redux, or similar frameworks.
  • Backend development experience with Node.js, C#, Go, Java, or similar technologies.
  • Experience interacting with smart contracts and blockchain systems (e.g., Solidity, Ethereum-based ecosystems).
  • Solid understanding of the transaction lifecycle: signing, submission, execution, confirmations, and failure handling.
  • Strong focus on security best practices when designing and integrating Web3 systems.
  • Experience building scalable distributed systems, including monitoring, logging, tracing, and performance optimization.
  • Ability to work across the stack and take ownership of features from architecture to production.

 

Responsibilities

 

  • Design and develop Web3-enabled applications, including frontend interfaces, backend services, and blockchain integrations.
  • Implement wallet connectivity and transaction flows, ensuring reliability and security.
  • Build and maintain integrations with blockchain nodes, RPC endpoints, and indexing services.
  • Work on DeFi-related functionality, including swaps, payments, settlement flows, and smart contract interactions.
  • Collaborate with product, design, and engineering teams to deliver scalable solutions.
  • Ensure system performance, reliability, monitoring, and observability across services.
  • Contribute to architecture decisions and continuously improve the platform’s technical foundations.

 

We offer

 

  • Competitive compensation based on experience.
  • Opportunity to work on cutting-edge Web3 and DeFi products.
  • Remote-friendly work environment with flexible collaboration.
  • Work with experienced engineers on high-impact blockchain systems.
  • Professional growth and the opportunity to expand across frontend, backend, and on-chain development.
