Principal Software Engineer

Malwarebytes is reimagining security to safeguard devices, data, and people — no matter their location, lifestyle, or means. What began in 2008 with one person helping another remove a malware infection has grown into a global leader in online protection, with an all-in-one suite of cybersecurity, privacy, and identity protection solutions that empower millions of people worldwide to enjoy their digital lives, free from threats and scams.

Our portfolio has grown far beyond malware removal into a full suite of award-winning cybersecurity, privacy, and identity solutions, from the free tools that have long served as a first line of defense to newer options for identity protection and personal data removal. The threat landscape keeps getting faster, stealthier, and more sophisticated, and we believe protection should be both powerful and refreshingly simple — because security that's too hard to use doesn't get used.

Built and beloved by experts, we combine world-class threat research with proprietary, AI-powered processes to deliver powerful digital protection that's always by your side.
