The ideal candidate will have real-world experience in a Red Team and previously worked on all stages of penetration testing from scoping to reporting.
You’ll need to be highly motivated, have an innovative mind-set and a good attention to detail. You will need to stay up to date with the latest techniques and threats and apply this knowledge to help protect Sophos and our customers.
This a great opportunity to help secure a world-leading cybersecurity company. As you’d expect you’ll be joining an organization that takes security seriously.
