Duo is on a mission to end the era of passwords and democratize advanced security technologies to protect everyone, not just the Fortune 500s. We're solving the biggest security challenge in the industry and want you to join us for the ride!

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 solve some of the most complex global business and security challenges faced today.

What you’ll do…

As a Principle Software Engineer you will be the core for implementation efforts for our Duo desktop application. This application helps people throughout the world keep their computers safe. You’ll be working with a team to build a multi-faceted product with native code on Windows, MacOS, Linux paired with a Python service infrastructure and React-based web application. This is a new product initiative with significant greenfield opportunities. You will help us make many core technical decisions.

We emphasize software craftsmanship and apply it our development practices. As a Principal Software Engineer you are expected to help mentor your Duo engineer peers. You will collaborate on technical direction, review code and be an owner over the quality of our software.

Skills you have…

• You have 7+ years of back end web application or native desktop application experience
• You love working with modern Python, Go, or C++
• You are a user of AWS including both high-level (e.g. RDS, Lambda) and low-level (e.g. EC2, VPC) services
• You have a history of writing performant, maintainable, testable code
• You have experience working with data at scale and real time processing. (e.g. Unified Logs, Kafka, Kinesis, Cassandra, RabbitMQ)
• You strive to make security simple to understand and easy to implement
• You value automated testing as much as writing expressive clean code
• You love automation — particularly CI/CD

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 in teams of high-performers who are passionate about a common goal.
• You revel in the opportunity to do it all; from Python to web front-end, to desktop!

This job may not be for you if…

• You only code alone and aren't willing to mentor and be mentored.
• 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.
