About the Role

We're looking to add a full-time Cybersecurity Engineer to our Hong Kong office to help protect our company's people, data, and infrastructure from the wilds of the internet. Our Cybersecurity Engineers work on firm-wide defenses, provide expertise and advice to other groups, lead employee cybersecurity awareness efforts, and handle event analysis and incident response responsibilities. The successful candidate will have a strong technical foundation, build solutions independently, bring good taste to solving security problems, and can explain the reasoning behind security practices.

Requirements

  • Have strong scripting or programming, and surrounding practices: interest and ability to automate in a real programming language, ability and desire to manage code and configs in version control, and knowledge of your editor (we don't care which editor)
  • A measured responder: can discuss trade-offs when it comes to cybersecurity, think about context, and understand what threat modeling is
  • Understands and practices good personal cybersecurity hygiene, and can talk to others about it (e.g. knows what a password manager is, uses one or has something reasonably better, and can walk someone through the trade-offs made)
  • Tapped into cybersecurity developments: follows cybersecurity news and can tell the difference between the latest cool hack by security researchers and what actually matters day-to-day
  • Have a positive and collaborative attitude: understands that a key component of cybersecurity is bringing others along with you on the journey
  • Fluency in English required
  • Strong technical foundation
  • Not afraid to build something themselves
  • Brings good taste to solving security problems
  • Can reason about and explain the "why" behind security practices
