We are Duo, and we’re here to democratize security for everyone. Our mission is to protect the mission of our customers like Facebook, Twitter, Kayak and Etsy by making security simple.

We’re a diverse crew of makers and builders, skaters and coders, filmmakers and DJs, teachers and students brought together by a shared belief in adding value to the world. This diversity allows us to bring an empathetic approach to tackle some of the most complex global business and security challenges faced today.

What we’ll do together…

As a Sr. Software Engineer on the Apps Team, you will bring your development skills to our already diverse and talented group. We'll work together within the agile scrum framework toward our goal of making security easy to understand and easy to implement. We tackle real problems for real users and push our product forward for the betterment of everyone.

Our challenge is an unusual one, while we spend the majority of our time building new features for our primary application in Python we also support a vast array of open source projects that span multiple languages including (but not limited to) Python, C, Java, Ruby, PHP, and Javascript. We don’t expect that you already know all of these, only that you are willing to learn and contribute to our team in a meaningful way. We emphasize software craftsmanship and apply it our development practices through Testing, Continuous Integration, Build Automation, and Mentorship. We prioritize team success highest and tend to swarm on sprint work to meet our collective goals

Skills you have…

• You are excited by the challenges of the security field and want to help make people safe.
• You have a history of writing performant, maintainable code using a server-side language.
• You value automated testing as much as writing expressive clean code.
• You already have experience with event-driven networking libraries like Twisted specifically; or asynchronous software development in general.
• You can go beyond the terminal to develop user interfaces that unlock the full potential of the software you write.
• Bonus Points for existing security expertise or experience with LDAP and Radius protocol.

3 Reasons why you should apply…

• You thrive having the autonomy to operate in a meaningful problem space solving real problems for real people.
• You work best within an empathetic team which is passionate about a common goal.
• You are happy when your end-users are happy and frustrated when they are frustrated.

This job may not be for you if…

• You only code alone and aren't willing to mentor and be mentored.
• You don’t want to continue to learn and grow along with your teammates.
• You lack a real passion for writing high-quality secure software that is backed by an equally mature approach to testing.
• You stress under the ambiguity of a problem and default to others to provide you with the answers.
• Your first instinct is to point out why something can’t be done rather than focusing on what the customer problem is.
• You tire at the thought of a steady, deliberate pace in both a product and company.
• You aren't looking to take your career to the next level at a best-in-class SaaS company.
