Fully Remote Software Engineer - Radley James

We’re working with a crypto-native DeFi trading platform, backed by a leading digital assets firm (client name kept confidential), to hire a Senior Backend Developer.

This is a hands-on role covering backend engineering, smart contract integration, and trading-adjacent systems, working closely with experienced engineers, product, and UX in a fast-moving, production-focused environment. What You’ll Be Doing

• Building and maintaining backend services and public APIs in Rust and Python

• Contributing to the evolution of a performance-critical DeFi trading platform

What We’re Looking For

• Strong experience with Rust and Python
• 3–4+ years in crypto / DeFi-native roles

• Understanding of DEXs and trading concepts (hands-on or theoretical)
• Comfortable operating production systems in a cloud environment
