Full-Stack Blockchain & Fintech Developer for Crypto & Forex Trading Platform

Remote · Colombia Full-time

We are launching a comprehensive financial trading platform that bridges the gap between traditional Forex markets and modern Digital Asset/Crypto trading. We are looking for an elite, full-stack fintech and blockchain developer (or senior architect) to build a highly secure, scalable, and compliant trading platform. This project demands deep knowledge of financial software engineering, high-throughput order matching engines, and ironclad security protocols. Core Responsibilities: - Architect and develop the core trading platform architecture from scratch (Frontend, Backend, and Database). - Build or integrate a high-frequency, low-latency Order Matching Engine for crypto order books. - Integrate institutional Forex liquidity providers and broker APIs (e.g., PrimeXM, OneZero, or MT4/MT5 bridges). - Implement secure crypto wallet infrastructure (Custodial/Non-Custodial, Multi-Sig setups, and hot/cold wallet management). - Build a responsive, real-time user interface utilizing WebSockets for live charting (TradingView integration), instant order execution, and user dashboards. - Ensure strict compliance framework integrations, including automated KYC/AML verification pipelines. - Deploy the entire infrastructure on AWS/GCP with enterprise-grade security, DDoS protection, and end-to-end data encryption. Required Qualifications: - Proven experience building operational Crypto Exchanges, DeFi protocols, or Forex brokerage platforms. - Mastery of modern web stacks (e.g., Node.js, Go, Rust, or Python for backend; React or Vue for frontend). - Comprehensive understanding of market depth, order books, liquidity aggregation, and financial accounting logic. - Experience with Solidity/Smart Contracts and major blockchain protocols (Ethereum, EVM chains, Solana). - Obsession with security best practices to prevent financial exploits, flash loan attacks, or data breaches. To Apply: Please submit a detailed proposal highlighting your past experience in fintech, Forex, or cryptocurrency platform development. You must provide a brief case study or repository example of an exchange engine or financial dashboard you have previously built. Use code with caution. Screening Questions Have you built a crypto exchange or Forex brokerage platform before? Please provide a brief overview of its architecture. How do you plan to handle the synchronization of high-speed Forex liquidity feeds alongside volatile crypto market data? What strategies and infrastructure do you use to ensure hot wallet keys remain secure from external breaches?
