  • Ruthlessly Prioritize: Proactively identify areas that would most benefit the improvement of our business, inclusive of the Incident Response program and with consideration of company/organizational objectives
  • Don’t Settle: Challenge the status quo; perform technology research, security research, and architecture reviews needed for a thorough understanding of the Twilio platform to understand what we are defending and how best to defend it
  • Draw the Owl: Building systems and services to make the most complex security problems simple and frictionless
  • Empower Others: Build, cultivate, and maintain positive relationships with internal customers to identify and facilitate solutions to increase the impact of the team’s work
