Senior Offensive Security Researcher

As an Offensive Security Researcher, you will be tasked with proactively researching the newest and most sophisticated attack techniques and working closely with some of the best security researchers in the industry to shape the future of cyber security. You will bring curiosity, persistence, and a drive to leave no stone unturned in the search for the next bypass. By being part of our team, your work will impact protection of tens of millions of customer endpoints worldwide, incl. 4 of Fortune10 and hundreds of Global2000, and you will have a chance to work on a industry-leading endpoint security product (recognized 6x in-a-row as Gartner Leaders, scoring highly in Mitre Att&ck, in Frost Radar, SE Labs and by others).

What Will You Do?

Primary responsibilities include:

• Proactively research and deeply understand the internals of the newest and most sophisticated attack techniques and exploits, and emulate these attacks to assess and improve our detection engines (incl. designing detections and writing behavioural detection signatures).
• Build tools to support detection assessments, create proofs of concept for the newest techniques and exploits, and develop automation flows to automate unconventional attacks and offensive frameworks.
• Work closely with the Threat Intelligence team and the research and engineering detection teams to provide guidance and highlight gaps in detection and visibility capabilities.

What Skills and Knowledge Will You Bring?

Ideal candidates will have:

• Multiple years of experience in security research, or offensive research, with a deep understanding of OS internals (Windows and/or, preferably, Linux).
• Hands-on experience coding in Python and C/C++.
• Deep understanding of the malware world, including how malware operates, well-known malware families, and evasion and exploitation techniques.
• An advantage would be: experience in malware analysis, both static and dynamic, and reverse engineering (x86/x64), understanding of existing antivirus internals, experience writing behavioural detection signatures.
