Malware Research Engineer

Here at Malwarebytes, we believe that when you’re free from threats, you’re free to thrive. It all started in 2008 with one person who needed help with a malware infection, and a community coming together to find solutions. In that moment in time a product was born for all people, with a mission to rid the world of malware. Our product has since grown and evolved, from removing malware, to protecting devices, to ever-changing prevention.

About Malwarebytes Inc.

Malwarebytes began after our founder, Marcin Kleczynski, accidentally infected his parents’ computer while downloading a video game as a teenager. At the time, there was no product that could fully solve the problem, so he set out to build one. That early experience shaped our mission: to create protection that works when people need it most.
Since then, the digital threat landscape has only grown more complex. Attackers are faster, stealthier, and more sophisticated, while traditional solutions often overwhelm people with complicated tools and settings. At Malwarebytes, we believe protection should be both powerful and refreshingly simple because if security feels too hard to use, people will not use it. That is why our aspiration is always to stay one step ahead: cutting through the noise, stopping threats others miss, and delivering peace of mind in an unpredictable digital world.
