.NET Developer Intern

Who we are

No call centre and no offshore help desk. When clients call, one of us picks up. Certification exams are paid for, and passing one comes with a raise.

About the role

Our Core Services 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. This is a remote internship. You will work with our team in Sioux City, and the stipend is paid monthly in Sri Lankan rupees. You will need at least 4 hours of overlap with US Central time. Reliable internet and a power backup are a must.

Day to day

• Profile slow endpoints and suggest fixes, such as adding an index or caching a result.
• Pair with other engineers over screen share to work through tricky problems.
• Raise pull requests on GitHub and respond to code review comments within a day.
• Present a short demo of your work to the team every two weeks.
• Debug failing builds in the GitHub Actions pipeline and note what caused them.
• Refactor old modules when asked, keeping behaviour the same.
• Add unit tests with pytest or Jest so new code does not lower coverage.
• Fix bugs from the Jira backlog, starting with small, well-defined tickets.

Requirements

• Undergraduates or recent graduates in IT, computer science, management or a related field.
• Available for the full internship period.
• Able to communicate clearly in written English on Slack and in pull requests.
• A GitHub profile with at least two projects you wrote yourself.
• Own laptop with at least 8 GB RAM and a reliable internet connection.
• Good grasp of at least one programming language: Python, Java, JavaScript or C++.

What you'll learn

• You will ship at least one feature that real users touch before the internship ends.
• How a production codebase is organised, deployed and monitored.
• Code review on every pull request, so expect a lot of feedback on naming, tests and structure.
• Writing tests is part of the job here, and you will get good at it.
