We believe in attack driven defense and value the understanding and the breaking of systems as highly as the designing and building of them. To this end we take on special research and development projects in our skunkworks Labs group that require different kinds of thinking and skill sets to tackle than our normal engineering process.

  • Collaborate with product and engineering to transition proof of concepts for commercialization
  • Externalize the fruits our research program to further Duo’s thought leadership and open source efforts

  • Expertise with one or more modern programming languages, preferably Python
  • Experience thinking like an attacker and bypassing existing security controls and assumptions
  • Broad, but not necessarily deep, experience across systems, web, mobile, and cloud environments
  • Strong understanding of security fundamentals and familiarity with modern security approaches
  • Demonstrated ability to innovate and brainstorm creative approaches to hard technical problems
