We're building and scaling the technical infrastructure behind one of the most advanced real-time trading platforms in the industry.. We’re seeking Low-Latency Java Developers to join the Pricing & Risk team, responsible for the core systems that process, price, and publish live financial market data across asset classes.
These systems are built for ultra-low latency, high throughput, and precision, supporting thousands of price updates per second across FX, options, equities, crypto, and commodities. This role is ideal for engineers who thrive on performance-critical challenges, want to build production-grade systems that directly impact trading, and enjoy working at the intersection of finance and cutting-edge engineering.
Requirements
3+ years of professional Java development experience, ideally in low-latency or high-throughput systems.
Strong proficiency in modern Java (Java 17 or 21) and multi-threaded concurrent programming.
Experience with lock-free architectures, LMAX Disruptor, or similar high-performance patterns.
Strong understanding of system design, fault tolerance, and horizontal scalability.
Good communication skills and ability to work effectively remotely.
Preferences:
Deep understanding of JVM internals, garbage collection tuning, and performance profiling.
Familiarity with Aeron, TIBCO Rendezvous, QuickFIX/J, or other messaging and protocol stacks.
Understanding of market data processing, FIX protocol, or real-time event pipelines.
Experience building and tuning Spring Framework–based systems for performance and reliability.
Solid grasp of network programming, UDP/TCP, and serialization techniques such as SBE or custom binary formats.

Knowledge of monitoring, metrics, and troubleshooting distributed systems (e.g. Pulse, Grafana, Prometheus).
Responsibilities:
Design, implement, and optimize ultra-low-latency pricing and risk components in Java.
Develop and maintain the core pricing pipeline.
Work on multi-asset pricing services, connecting to multiple market data vendors (FIX, TIBCO, Aeron, HTTP/WebSocket, etc).
Build and maintain vendor adapters for data ingestion and publishing bridges to downstream systems.
Profile and tune performance at every layer.
Collaborate with pricing analysts, risk specialists, and DevOps engineers to ensure stability and precision in live trading environments.
Participate in code reviews, testing (unit, integration, and performance), and continuous delivery.
Document system behaviour, configuration flows, and new service patterns to ensure long-term maintainability.
Stay current with advancements in low-latency Java, messaging frameworks, and financial data technologies.
