Software Engineering Intern

Our main product is a payroll and timekeeping app for hourly workforces, sold by subscription and supported from Karlsruhe. Krause Systems builds scheduling and dispatch software for field service companies, from two-truck plumbing outfits to regional HVAC contractors.

The internship:

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 Karlsruhe, and about a third of the team works remotely from other countries. The internship is fully remote. Interns join our Karlsruhe team on daily calls and get a named mentor. Core hours are 10:00 to 15:00 CET.

• Raise pull requests on GitHub and respond to code review comments within a day
