  • Excellent debugging, analytical reasoning, and written/verbal communication skills
  • Demonstrated ability to drive technical initiatives across teams and influence without authority

Preferred Qualifications

  • Track record of contributions to OpenJDK or other open-source runtime/compiler projects
  • Experience with memory-safety techniques, fuzzing, or security hardening of native runtimes
