We are working in collaboration with a client to source a Senior Java Developer. The Senior Java Developer is required for a small trading technology firm focused on crypto markets, working directly on exchange connectivity and low-latency trading systems.

You’ll be working directly on live trading systems, solving real-world problems around exchange behaviour, performance and connectivity, in a collaborative team of experienced engineers. This is not a generic backend or platform role. The focus is specifically on building and optimising connectivity into crypto exchanges, where each venue has its own quirks and performance considerations.

The Role

  • Build and optimise connectivity into crypto exchanges (APIs, FIX and proprietary protocols)
  • Improve latency and performance across real-time trading systems
  • Work with live market data and order flow in production environments
  • Identify efficient ways of routing messages without relying on expensive infrastructure
  • Bring practical knowledge of how different exchanges behave and how to get the best performance from them
  • Contribute to system design decisions around connectivity, latency and performance

Key experience:

  • Strong development background in Java (or C/C++)
  • Experience working in low-latency or performance-critical systems
  • Hands-on experience with crypto exchange connectivity (e.g. Binance, OKX, Coinbase or similar)
  • Understanding of how different exchanges behave and how to optimise connectivity and routing
  • Comfortable working in Linux/Unix environments

Nice to have:

  • Experience with FIX or market data systems
  • Experience working in trading or real-time environments
  • Scripting experience (Python or similar)

This is a hands-on role within a flat hierarchical team where you’ll have direct impact on how the firm connects to and interacts with exchanges, rather than working on isolated components. You’ll be working closely with traders and engineers in a small, collaborative team, contributing across different areas rather than operating in a silo.
