In 2017, we were honored to receive the JPMorgan Chase Hall of Innovation Award for our truly unique, automated, and scalable static file analysis, malware classification and malware hunting technologies. Our pioneering technologies, exceptional products, and successful customer deployments also drove a $25 million investment in ReversingLabs, backed by some of the savviest investors in the world.

In this day and age, with systems and people under attack day and night by highly advanced cyber threats, a swift but detailed analysis of current threats and attack vectors is necessary. Given the number of such attacks, this is no small feat.

As a member of the threat analyst team, you will often have to put yourself in the attacker’s shoes, correlate even the tiniest clues with millions of metadata records, and try to connect the dots to completely understand the attack chain. Finally, to prevent such attacks from happening again, you will need to transform your knowledge into a rule-based format that our analysis solutions understand, effectively shielding other potential victims.

Of course, we don’t expect you to be able to tackle threats right off the bat. Based on your skill level, you will undergo a specially crafted training during the first few months to sharpen your skills before entering the arena. Do you have what it takes?
