Intercontinental Exchange (ICE), owner of the New York Stock Exchange, 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.
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.
Knowledge and Experience
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.
Show the full description
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.
Nice to have
Experience building observability data pipelines (metrics collection, processing, and storage) is a strong advantage. Familiarity with Prometheus, VictoriaMetrics, or Grafana is a plus.
Practical use of AI tools (Claude, Copilot, Cursor) for performance work such as GC log analysis, query writing, or harness scaffolding.
