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.
