Engineering Intern, Platform

Our website and apps help renters search listings, schedule tours and submit applications. Support shifts are shared, so engineers spend a few hours a quarter answering customer tickets.

The internship

We need a student who can write clean code, test it and explain what it does. Prior internships are not required. Fully remote. You can work from anywhere in the US. Please make sure you have a quiet place to work and a solid internet connection.

What you'll do

• Build REST API endpoints and document them in Postman or Swagger
• Update the README and internal Confluence pages when you change how something works
• Add unit tests with pytest or Jest so new code does not lower coverage
• Query and update data in PostgreSQL or MySQL, including simple migrations
• Raise pull requests on GitHub and respond to code review comments within a day
• Join the daily 15-minute standup on Google Meet and post a short written update in Slack
• Profile slow endpoints and suggest fixes, such as adding an index or caching a result

Requirements

• Available 40 hours a week for the full internship
• Authorized to work in the US. CPT and OPT candidates are welcome to apply
• Currently enrolled in a bachelor's or master's program, graduating 2026 or 2027
• Own laptop with at least 8 GB RAM and a reliable internet connection
• Good grasp of at least one programming language: Python, Java, JavaScript or C++
• Available for 30 to 40 hours a week for the full internship period

What you'll learn

• Certificate and letter of recommendation on completion, plus a pre-placement offer for strong performers
• Code review on every pull request, so expect a lot of feedback on naming, tests and structure
• Writing tests is part of the job here, and you will get good at it
• Weekly 1:1 with your mentor to go over what went well and what to work on next
