Software Engineering Intern

Our website and apps help renters search listings, schedule tours and submit applications.

Overview:

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. You can work from home anywhere in Iceland. 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:

• 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.
• Build REST API endpoints and document them in Postman or Swagger.
• Refactor old modules when asked, keeping behaviour the same.
• Fix bugs from the Jira backlog, starting with small, well-defined tickets.
• Debug failing builds in the GitHub Actions pipeline and note what caused them.

What we're looking for:

• Currently enrolled in a bachelor's or master's degree, graduating 2027 or 2028.
• Based in Iceland for the duration of the internship.
• Must be able to overlap at least 4 hours a day with the team's working hours.
• Good grasp of at least one programming language: Python, Java, JavaScript or C++.
• Available for 30 to 40 hours a week for the full internship period.
• Able to communicate clearly in written English on Slack and in pull requests.

What you get out of it:

• Weekly 1:1 with your mentor to go over what went well and what to work on next.
• Writing tests is part of the job here, and you will get good at it.
• You will ship at least one feature that real users touch before the internship ends.
• Certificate and letter of recommendation on completion, plus a pre-placement offer for strong performers.
