Senior Performance Engineer - Low-Latency Java

Intercontinental Exchange (ICE); Atlanta (GA); On-site; USD 180,000 - 230,000; Full time

Job summary

Intercontinental Exchange (ICE) is hiring a Lead Performance Engineer for its Clearing Performance Engineering team in Atlanta. You will own performance strategy for event-driven Java platforms that run critical clearinghouses, where end-of-day processing windows are measured in minutes.

You will lead deep-dive investigations, build test harnesses, mentor peers, and serve as the go-to voice on performance trade-offs across application, JVM, OS, and hardware layers.

Qualifications

• Bachelor’s degree in Computer Science, Engineering, or equivalent experience.
• 8+ years in performance engineering, performance testing, or Java development on high-volume, low-latency systems.
• Deep JVM expertise: heap and thread dump analysis, GC log interpretation, memory and CPU profiling.
• Java plus scripting (Python, Groovy, or shell) for automation and harness development.
• Hands-on experience with load generation (JMeter, Gatling, or custom harnesses).
• Experience with message-based architectures (Kafka, IBM MQ, or equivalent).
• Strong written and verbal communication.

Responsibilities

• Lead performance investigations on CPU-bound, multi-threaded Java systems, from application code down to JVM, OS, and hardware.
• Model how systems scale with data volume and instrument counts, and produce capacity projections that guide architecture decisions.
• Identify time-critical paths in batch and event pipelines, and propose and validate fixes such as head-start or out-of-band processing.
• Build test harnesses and realistic workloads that catch version-to-version regressions.
• Tune thread pools, GC, and heap for high-throughput, latency-sensitive pipelines.
• Turn findings into clear, data-backed recommendations for architects, developers, and business stakeholders.
