The posting, as the company wrote it
About the Position
We're looking to add a full-time, passionate Cybersecurity Engineer to our London 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 some of the event analysis and incident response responsibilities of the firm. We're looking for someone who has a strong technical foundation, who is not afraid to build something themselves, who brings good taste to solving security problems, and who can reason about and explain the “why” behind security practices.
About You
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
