Senior Information Security Engineer

Duo Security, now a part of Cisco, is the leading provider of Trusted Access security and multi-factor authentication delivered through the cloud.

Duo’s mission is to make security simple for everyone. We were born from a hacker ethos and a desire to make the Internet a secure place. We believe in empowering people to follow their passions inside and outside of the office and enable every employee to bring their whole self to work.

Our team is our secret weapon. We run the spectrum from artists to analysts, low-key to high energy, and bring together a diversity of skill sets, experiences, and perspectives to solve what we consider to be the world's most pressing geopolitical challenge — transforming the security industry as we know it. Together we build solutions that are easy, effective, trustworthy, and enduring. And that’s why we are the most loved and trusted company in security.

As a Senior Information Security Engineer, you will provide technical leadership to the team while you build tools to keep the security company secure. You will democratize security as a practitioner, and you will be Duo’s “customer zero” implementing and providing feedback on our own product.

As a member of the Corporate Security Engineering team team, you will create a security foundation across the organization, through tools, automation, and best practices. You'll experiment with cutting edge technologies to uncover the best way to scale this foundation to all of Duo, Cisco, and beyond.

  • Deep experience with cloud security and an understanding of how to automate security within AWS or GCP
  • Highly skilled in Python, Go or a similar modern high-level language
