About the position

You will build and improve infrastructure surrounding KOMOJU by making our platform highly reliable, efficient, and scalable. You will do this by automating all things infrastructure.

  1. 1

    Initial Screening

    Your application will be reviewed by our engineers. Rather than just your work history, we’re looking for something that demonstrates a passion for programming.
