What's Guardio?

Guardio is a B2C cybersecurity startup offering security and privacy solutions directly to consumers - regular people, not corporate companies. We develop products you’d want for yourself, your parents, family, and friends. Our goal is to protect real people from cyber problems and crime. We try and avoid buzzwords, but sometimes those keywords are necessary: we help our customers avoid and combat the modern world’s security threats, like phishing, financial scams, malware, browser hijacking, identity theft, data leaks, and a whole lot more.

Guardio is a relatively small company (we just passed 90 people) on a rapid growth path, and we’re looking for core team members to join our team. We already have well over a million registered customers and plenty of new products and features in the pipeline.

So, what’s the job?
