Core Java Developer - Low Latency Trading Technology

Location: United Kingdom (Remote)

We're working with a high-performance financial technology business whose software sits directly in the execution path of real-time electronic trading.

This is not a Spring Boot microservices environment.

This is an opportunity for an engineer who enjoys solving performance problems at the lowest levels of the stack. The team builds and maintains low-latency trading infrastructure used by banks, brokers and market participants globally.

You'll work on market connectivity, FIX integration, execution workflows, smart order routing and real-time trading systems where latency, throughput and reliability matter.

We're particularly interested in engineers who have built systems from the ground up and who understand what happens underneath the frameworks.

Key Requirements:

* Strong Core Java
* Multi-threading, concurrency and locking
* Memory management and garbage collection optimisation
* Low-latency system design
* FIX Protocol
* Trading technology experience
* Smart Order Routing, market connectivity or electronic trading desirable
