The program

Saltbox Telecom is hiring a Software Developer Intern for Summer 2027. 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. You will intern remotely with our team in Nantes. We have hosted remote interns from several countries before. Core hours are 10:00 to 15:00 CET. Day-to-day communication is in Slack and Google Meet.

What you'll do

• Update the README and internal Confluence pages when you change how something works
• Join the daily 15-minute standup on Google Meet and post a short written update in Slack
• Query and update data in PostgreSQL or MySQL, including simple migrations
• Profile slow endpoints and suggest fixes, such as adding an index or caching a result
• Debug failing builds in the GitHub Actions pipeline and note what caused them
• Build REST API endpoints and document them in Postman or Swagger
• Add unit tests with pytest or Jest so new code does not lower coverage
• Pair with other engineers over screen share to work through tricky problems
