About the Right Team Member

As a Platform Engineer, you will help accelerate our engineering team as we deploy frequently to production for 100+ services. You will help create systems, tools, and practices so that we can scale with increasing confidence.


  • Professional experience designing, building, and operating distributed systems at large-scale in an AWS environment.
  • Use existing commercial and open source tools to create a robust, reliable, and performant platform.
  • Determine when these tools are insufficient and decide when it's time to write our own (and then write them).  Our go-to languages are Python and Java.
  • Excited by big, complicated problems and try to solve them with creative, elegant, and simple solutions.
  • Communicate problems and their solutions to other engineers as well as a less technical audience.
  • Look at a process and you instinctively want to automate it.
  • You value simplicity and strive to eliminate unnecessary complexity.
  • At least 5 years of professional programming experience.
  • You treat infrastructure as code.  Prior experience with Terraform is a plus.
  • Passionate about your craft and want to be surrounded by like-minded individuals.

We are an equal opportunity employer and value diversity at our company. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.
