• Tune JVM garbage collection settings to remove latency outliers in production environments.
• Contribute to CI/CD pipeline automation and debug customer-reported issues related to JVM health.
• Profile JVM performance using JFR, JMX, and async-profiler tools to monitor and resolve crashes.

What we're looking for

• 6+ years of professional Java engineering with at least 2 years in performance-critical production systems.
• Mastery of modern Java (v17+) and deep understanding of the memory model, generics, concurrency primitives.
• Expertise in JVM garbage collection tuning and profiling using tools like async-profiler, JFR, JMX.
• Proficiency in concurrent programming with java.util.concurrent, Fork/Join, CompletableFuture, and lock-free algorithms.
