Software Engineering Intern

Who we are:

Our field services team covers retail chains, hospitals and banks, dispatching technicians to over 4,000 sites. Corwin is a managed services provider with 350 employees, supporting more than 1,500 client organisations across Finland. Lunch is usually whatever is closest to the client site.

About the role:

Our Integrations 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. Remote within Finland. The team meets in Tampere once a quarter, travel covered. Please make sure you have a quiet place to work and a solid internet connection.

Day to day:

Profile slow endpoints and suggest fixes, such as adding an index or caching a result. Query and update data in PostgreSQL or MySQL, including simple migrations. Add unit tests with pytest or Jest so new code does not lower coverage. 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. Write and test backend features in Python or Node.js under the guidance of a senior developer.

Who can apply:

Eligible to work in Finland. Based in Finland for the duration of the internship. Currently enrolled in a bachelor's or master's degree, graduating between December 2027 and June 2028. Available for the full internship period. Must be able to overlap at least 4 hours a day with the team's working hours. Some experience with Git, even if only on college or personal projects. Good grasp of at least one programming language: Python, Java, JavaScript or C++.

What you get out of it:

Code review on every pull request, so expect a lot of feedback on naming, tests and structure. How a production codebase is organised, deployed and monitored.
