Software Developer Intern

Who we are:

We run a marketplace with over 300,000 active sellers and fulfillment centers in four regions. Our engineering, trust and safety, and customer support teams work across offices in Phoenix and several other countries. Product reviews happen on Thursdays, with demos of whatever shipped that week.

Overview:

The intern will work on internal tools and APIs used by our support and operations staff. Daily standup on Google Meet, everything else async on Slack. You can work from home anywhere in the US. We have no office requirement.

Responsibilities:

• Add unit tests with pytest or Jest so new code does not lower coverage
• Debug failing builds in the GitHub Actions pipeline and note what caused them
• Build REST API endpoints and document them in Postman or Swagger
• Join the daily 15-minute standup on Google Meet and post a short written update in Slack
• Write and test backend features in Python or Node.js under the guidance of a senior developer

Requirements:

• Currently enrolled in a bachelor's or master's program, graduating 2027 or 2028
• Available 40 hours a week for the full internship
• Authorized to work in the US. CPT and OPT candidates are welcome to apply
• Some experience with Git, even if only on college or personal projects
• A GitHub profile with at least two projects you wrote yourself
• Own laptop with at least 8 GB RAM and a reliable internet connection
• Comfortable writing simple SQL queries (SELECT, JOIN, GROUP BY)

Nice to have:

• Contributions to an open source project, however small
• Knowledge of Linux command line basics
• Exposure to Docker or a cloud platform such as AWS or GCP

What you'll learn:

• Weekly 1:1 with your mentor to go over what went well and what to work on next
• How a production codebase is organised, deployed and monitored
• Certificate and letter of recommendation on completion, plus a pre-placement offer for strong performers
• Writing tests is part of the job here, and you will get good at it
