Software Engineering Intern

Profitable, no outside investors, and no plans to take any. We grow when customers pay us. Small accounting firms in Baden-Württemberg use our engagement letter and e-signature tool, and most heard about us from a colleague.

The internship:

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. Remote, open to candidates across Germany. Hours are flexible, with one short team call each morning. Clear written English is a must, as the team works across time zones.

What you'll do:

• 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.
• Update the README and internal Confluence pages when you change how something works.
• Profile slow endpoints and suggest fixes, such as adding an index or caching a result.
• Build REST API endpoints and document them in Postman or Swagger.
• Raise pull requests on GitHub and respond to code review comments within a day.
• Fix bugs from the Jira backlog, starting with small, well-defined tickets.

Requirements:

• Based in Germany for the duration of the internship.
• Currently enrolled in a bachelor's or master's degree, graduating 2027 or 2028.
• Available for the full internship period.
• Able to communicate clearly in written English on Slack and in pull requests.
• Available for 30 to 40 hours a week for the full internship period.
• Good grasp of at least one programming language: Python, Java, JavaScript or C++.
• A GitHub profile with at least two projects you wrote yourself.
