Software Engineering Intern

Who we are

Traffic during holiday peaks can reach ten times normal levels, and the platform is built for it. Core hours are 10 to 3, and the rest of the day is flexible.

This is a hands-on coding internship. Most of the work is in Python and Node.js, with some SQL and a bit of shell scripting. The internship is fully remote. Interns join our Cary team on daily calls and get a named mentor. Core hours are 9:00 AM to 1:00 PM US Eastern.
