Blockchain & DApp Developer (Remote)
Budget: $15 – $25 USD
Pay: USD $20 - $50 / hour
Location: In Remote (No Mexico)
CrypForexBridge is seeking a Blockchain & DApp Developer for an innovative project integrating blockchain, Web3, and Forex/Crypto markets into a modular, secure, and scalable platform.
The architecture will combine a Node.js backend with smart contracts on Ethereum or EVM-compatible chains. Node.js will handle off-chain processes such as user authentication, rate aggregation, and connections to traditional systems (including banking APIs), while smart contracts will manage on-chain transactions with full transparency.
Responsibilities
Design and develop smart contracts in Solidity for crypto-to-crypto swaps and fiat-pegged token management.
Integrate the Node.js backend with blockchain via Web3.js.
Implement APIs for real-time crypto and forex market data.
Apply development best practices: use test networks for QA, conduct smart contract audits, and build a modular architecture.
Collaborate in the system’s evolution toward later phases, including multi-chain integration and additional modules.
Requirements
Proven experience in blockchain and DApp development.
Strong proficiency in Node.js and related frameworks.
Experience with Solidity, Web3.js, and the Ethereum/EVM ecosystem.
Knowledge of decentralized architectures and DeFi protocols.
Ability to integrate external APIs and data oracles.
Intermediate/Advanced English for team communication.
Nice to Have
Experience with atomic swaps and DEX liquidity pools.
Familiarity with stablecoins and asset tokenization.
Experience in multi-chain scalability and asset bridges (cross-chain bridges).
We Offer
100% remote and flexible work.
High-impact project at the intersection of crypto and forex.
International and multidisciplinary team.
Competitive pay: USD $20 - $50/hour, depending on experience.
Apply by sending your portfolio, GitHub, and relevant experience in blockchain and Node.js.
