The Application Security team is responsible for ensuring that each engineer at Duo Security is enabled & supported throughout the Secure Development Lifecycle (SDL) to build security-resilient software. Whether for internally built technologies that help to “engineer the business,” or to delight our customers with innovative products & services, Duo’s Application Security team provides its capabilities across the entire business unit to reduce overall risk.

What you’ll do…

• Lead various types of Application Security technical initiatives to assist in furthering the maturity and security posture of Duo and its products.
• Work closely with teams, people, and leaders outside of AppSec to build positive relationships.
• Provide security guidance on feature designs and specifications
• Work closely with engineers on identifying and providing guidance on risk by reviewing architecture and implementation artifacts.
• Perform code reviews and audits of new and existing features.
• Identify and implement new ways that we can validate the security of Duo products and its development practices at scale.
• Support product security incident response escalations, coordinate 3rd-party security assessments, provide ad-hoc technical security expertise to product, sales, & engineering teammates.
• Research, build and implement tools, libraries & frameworks that aid developers in writing secure code.

Skills you have…

• You have a strong understanding of many vulnerability classes and how they occur across a variety of languages including Python, Javascript, Java, C, C#, and Objective-C. An expertise in one or more of those languages is highly desirable.
• You’re comfortable manually auditing code for vulnerabilities and using both commercial and custom static & dynamic code analysis tools (e.g. burpsuite, bandit, dlint)
• You are able to mentor and be mentored on security practices, controls and bring an influential flair to your audience whether it is one on one, during a presentation, or workshop.
• You understand security engineering principles, and how to seriously consider when a “best practice” may not be, in fact, the best choice or positively impact actual security and our customers.
• Have been a part of a PSIRT team or have a solid understanding of the concepts and methodology

4 Reasons why you should apply…

• You’re excited to be part of building an ever-maturing application security program that covers the Security Development Lifecycle, from training through incident response.
• You love to communicate in a friendly, encouraging manner with software engineers and product managers, helping to not only identify security issues, but also a mentor and advocate on solutions.
• You’re passionate about security, but understand each control or process has a “cost” that must be thought about critically, and from the point-of-view of many stakeholders.
• You want to continuously elevate your skills and the skills of your teammates.

4 Reasons why you SHOULDN’T apply….

• You only find excitement in breaking software. This role requires a broad participation in realizing a world-class application security program that leverages many talents at once.
• Getting work done quickly is more important than how you present that work. We pride ourselves in detail-oriented, well-written communications -- whether on reports or email.
• You don’t enjoy self-management of many tasks of various priority levels that can shift day-to-day. We value accountability of work that spans across tactical & strategic goals.
• You are a lone wolf and prefer not to work on a team where collaboration and insight focuses the team for success on a daily basis.
