  • Excellent communication and teamwork capabilities, with experience in agile development environments
  • Proven ability to offer constructive feedback and mentorship to junior engineers
  • Experience in test automation and tooling/infrastructure development
  • Background in performance profiling (sampling and instrumentation)
  • Familiarity with contemporary Intel and ARM hardware
ADDITIONAL ADVANTAGES FOR EXPERIENCE WITH:
  • Working knowledge of compilers, linkers, and other toolchain components
  • Familiarity with benchmarking frameworks such as Google Benchmark, JMH, or similar
  • Understanding of hardware performance counters and their effective use for performance analysis
  • Experience with cloud platforms like AWS, Azure, or GCP
  • Experience in establishing CI/CD pipelines
