We are looking for a Low Latency Java Developer to join our client's New York technology team. This role is central to building and optimizing the ultra-low latency trading infrastructure that underpins our strategies. Candidates with investment bank or electronic trading backgrounds and proven experience in Aeron (similar to Sequencer) are strongly preferred. Key Responsibilities • Design, develop, and maintain low-latency Java trading applications. • Implement high-performance messaging systems leveraging Aeron. • Optimize systems for microsecond-level latency through JVM tuning, lock-free data structures, and concurrency design. • Partner with trading, quant, and infrastructure teams to deliver scalable solutions for production environments. • Troubleshoot and resolve performance bottlenecks in real time. Requirements • 5+ years of Java development experience with a strong focus on low-latency/high • throughput systems. • Hands-on expertise with Aeron or similar messaging systems (Sequencer, Chronicle • Queue, etc.). • Strong background in multi-threading, concurrency, and lock-free programming. • Experience with networking protocols (TCP, UDP, Multicast). • Proven track record in financial services, hedge funds, or investment banks. • Deep knowledge of JVM internals, GC tuning, and performance profiling. Nice to Have • Exposure to exchange protocols (FIX, ITCH, OUCH). • Experience with C++ or Rust in low-latency contexts. • Familiarity with systematic trading or market data distribution.
