Software Engineer Intern

About Fernhill Systems:

More than 9,000 organisations use our HR and payroll suite, from regional hospitals to school districts. Public sector agencies, utilities and large health systems licence our asset management platform under multi-year contracts.

About the role:

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. You can work from home anywhere in Sweden. We have no office requirement. Normal working hours, Monday to Friday. Strong written English is important, since much of our work is async.

What you'll do:

• 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
• Present a short demo of your work to the team every two weeks
• Profile slow endpoints and suggest fixes, such as adding an index or caching a result
• Write and test backend features in Python or Node.js under the guidance of a senior developer
• Fix bugs from the Jira backlog, starting with small, well-defined tickets
• Build REST API endpoints and document them in Postman or Swagger

What we're looking for:

• Currently enrolled in a bachelor's or master's degree, graduating between December 2027 and June 2028
• Based in Sweden for the duration of the internship
• Some experience with Git, even if only on college or personal projects
• Comfortable writing simple SQL queries (SELECT, JOIN, GROUP BY)
• Must be able to overlap at least 4 hours a day with the team's working hours

What you'll learn:

• Code review on every pull request, so expect a lot of feedback on naming, tests and structure
• Certificate and letter of recommendation on completion, plus a pre-placement offer for strong performers
• You will ship at least one feature that real users touch before the internship ends
• Writing tests is part of the job here, and you will get good at it

Duration: 4 months

Start date: Feb 2027

Stipend: SEK 20,000-SEK 22,500/month

What we offer:

• Online learning budget
• Flexible hours
• Possibility of a full-time offer
• Internet allowance
• Letter of recommendation

Duration: 4 months. Start: Feb 2027.
