Application Engineer

What we’ll do together…

As an Application Engineer on the Integrations Team, you will be pivotal to Duo’s success and growth around strategic partnerships. You will work within the engineering team to support our technical partners as they integrate with our core platform. Our largest customers and strategic partners may rely on enterprise technologies from Oracle or SAP and this team is responsible to ensure Duo’s solutions integrate with and compliment enterprise systems.

You will develop product expertise with Duo’s SDKs and APIs to guide our partners through their solution development, documentation, deployment, and go-to-market activities. This team owns the Duo open source plugins and SDK software that enables big deals to happen. We write and maintain code in 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.

Bring your management and development skills to our already diverse and talented group. We'll work together within the agile scrum framework toward our goal of making security simple to understand, easy to implement, and seamlessly integrated into the world’s most popular software products.

Skills you have…

  • You are excited by the challenges of the security field and want to help make people safe.
  • You are comfortable understanding and solving technical problems for end users, partners, and internal systems alike.
  • You have a history of writing performant, maintainable full-stack software.
  • You have exceptional verbal and written communication skills as evidenced by a history of authoring excellent documentation.
  • The ability to see and articulate optimization opportunities in a technical system or workflow. The drive to execute impactful work to make things better.
  • Bonus Points for existing security expertise, partner management, or client relations.

3 Reasons why you should apply…

  • You thrive having the autonomy to operate in a meaningful problem space while helping advance Duo’s technical platform.
  • You work best within an empathetic team that is passionate about a common goal.
  • You are happy when users are happy and frustrated when they are frustrated.

This job may not be for you if…

  • You prefer to work alone and don’t like to speak up when it means helping others.
  • You don’t want to continue to learn and grow along with your teammates in a developing area of an already successful business.
  • 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.
