Artemis Talent is partnering with a leading trading technology firm building high-performance, real-time trading systems used across global markets.

This is not standard backend engineering. You’ll be working on latency-sensitive infrastructure across order management, execution, and market data where performance and reliability are critical.

The Role

• Design and build low-latency, high-throughput Java systems
• Optimise performance across latency, concurrency, and memory
• Contribute to mission-critical trading platforms (OMS/EMS, market data)
• Work closely with engineering and business stakeholders in a live trading environment

What They’re Looking For

• Strong Java experience (6+ years)
• Background in low-latency / high-performance systems
• Deep understanding of:
• Concurrency & multi-threading
• JVM tuning & memory optimisation
• Network programming (TCP/IP, NIO)
• Experience within trading systems / financial markets
• Exposure to FIX or similar messaging protocols

Why Join

• Work on real-time trading infrastructure
• Solve complex performance challenges at scale
• High-impact role in a fast-paced engineering environment

This is a role for engineers who understand production trading systems — not just code.

You will have real input into new technology at the fore of a re-architecture.
