The program:

Saltbox Telecom is hiring a Software Engineering Intern for Jun 2027. Our Internal Tools team is five engineers working fully remote across two time zones. The intern picks up small backend tickets first and moves to bigger features once comfortable. Our headquarters is in Nantes, and about a third of the team works remotely from other countries. 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. Please make sure you have a quiet place to work and a solid internet connection.

Responsibilities:

• Profile slow endpoints and suggest fixes, such as adding an index or caching a result.
• Join the daily 15-minute standup on Google Meet and post a short written update in Slack.
• Raise pull requests on GitHub and respond to code review comments within a day.
• Update the README and internal Confluence pages when you change how something works.
• Write and test backend features in Python or Node.js under the guidance of a senior developer.
• Debug failing builds in the GitHub Actions pipeline and note what caused them.
• Fix bugs from the Jira backlog, starting with small, well-defined tickets.

Preferred qualifications:

What you'll learn:
