About You
Company context from the listing:
- Have strong scripting or programming, and surrounding practices: You have an interest and ability to automate in a real programming language, ability and desire to manage your code and configs in version control, and knowledge of your editor (we don't care which editor, though)
- A measured responder: Not everyone should be locking their entire lives down in the name of security. You can discuss trade-offs when it comes to cybersecurity, think about context, and understand what threat modeling is
- You understand and practice good personal cybersecurity hygiene, and can talk to others about it: For example, you know what a password manager is, and either use one or have something which you can reasonably argue is better, and can walk someone through the tradeoffs you've made (Seriously, we’ll ask you about this sort of thing during the interview process)
- You’re tapped into cybersecurity developments: You follow cybersecurity news, but can tell the difference between the latest cool hack by security researchers and what actually matters in your day-to-day
- Have a positive and collaborative attitude: You understand that a key component of cybersecurity is bringing others along with you on the journey
- Fluency in English
