Sr Java Engineer Low Latency Saint Georges (Saint-Georges)

This client is seeking a senior Java engineer to design and build distributed, high-throughput systems that process real-time data under strict low-latency requirements.

About the Role

You’ll be working on performance‑critical infrastructure where milliseconds matter, contributing to systems that handle large volumes of streaming market data.

Responsibilities

• Design, build, and optimize distributed, high-throughput Java applications for real‑time data processes
• Engineer systems to meet demanding low‑latency and performance targets
• Develop and maintain scalable, fault‑tolerant services that handle high‑volume data streams
• Profile, tune, and troubleshoot performance bottlenecks across the stack
• Collaborate with trading, quant, and infrastructure teams to deliver reliable production systems

Qualifications

• Solid, hands‑on experience designing and building distributed, high-throughput Java systems
• Proven track record with real‑time data processing and low‑latency engineering
• Deep understanding of concurrency, multithreading, and JVM performance tuning
• Experience with high‑volume, scalable, fault‑tolerant architectures
• Solid grasp of data structures, algorithms, and system design

Required Skills

• Background in trading, financial markets, or other latency-sensitive domain
• Experience with messaging/streaming technologies (e.g., Kafka, Aeron, Chronicle) and in‑memory data grids
