If you’re enthusiastic about innovative approaches to problem-solving, we would love to speak with you about joining our team!

What are we looking for?

We are looking for talented security researchers, people who look at the world differently, who explore, "hunt" and live to beat the system and challenge it. People who are in pursuit of outsmarting the malware and overcoming it.

What will you do?

  • You’ll research and find new and innovative ways to detect, prevent and protect against the biggest and most prioritized threats we deal with.
  • You will be part of strategic and long-term research projects that would involve deep research of OS internals, research for new detection techniques, and novel threats.
  • Continually learning about emerging threats, techniques, and new technologies on a regular basis.
  • Besides new methods and technologies, you’ll also suggest how existing techniques and technologies can be improved for better coverage or accuracy.
  • Initiate and propose new features and capabilities, leveraging personal experience and expertise in security research.
  • You will also be encouraged to write white papers, blogs, and articles.

What experience or knowledge should you bring?

  • Ability to perform both offensive and defensive security research
  • Proven experience (at least 3 years) with malware analysis (statically and dynamically) and reverse engineering (x86/x64).
  • Experience and familiarity with the malware world (how the malware operates, techniques, infamous families).

  • Experienced with C, C++, and Python programming.
  • Advantage
    • Knowledge or experience developing bypasses or self-protection mechanisms for EDR, EPP, and AV technologies
    • Understanding of existing EDR, EPP, and AV internals.

Why us?

Because you will work on real-world problems with risks of millions of dollars (protecting against Ransomware and other threats) and make an impact by preventing our customers from appearing in global news after being attacked.
