  • Collaborate with cross-functional teams — from AI researchers to cloud infrastructure engineers — to ensure storage meets the needs of cutting-edge AI workloads.
  • Mentor and guide other engineers, fostering a culture of technical excellence, innovation, and collaboration.
  • Continuously evaluate emerging technologies and trends to anticipate the future of AI-native storage.
