  • Experience with CPU hardware profiling tools.
  • Strong grasp of computer science fundamentals such as algorithms and data structures.
  • Critical thinking and ability to work independently without direct supervision.
Nice-to-Haves
  • Entrepreneurial spirit and previous experience in early stage start-ups.
  • Experience with open-source development.
