  • Proven ability to design and implement high-performance, scalable distributed systems
  • Experience with cloud platforms (e.g. AWS or GCP), automation, and Infrastructure as Code
  • Understanding of operating live systems with large user volumes
  • Highly autonomous and proactive, with a strong sense of ownership
  • Humble, pragmatic mindset and a respectful attitude toward others and their work
  • Passion for games and building technology that enables others to succeed
