Java Developer Intern

About Chalkmark Labs:

Since 2009, the company has sold practice management software to dental and veterinary clinics in Switzerland. Clients range from single-location retailers to franchise groups with hundreds of stores, all running our point-of-sale and loyalty software.

Overview:

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. We are headquartered in Basel and have been hiring remotely since 2020. This is a remote internship. You will work with our team in Basel, and the stipend is paid monthly in USD. Working hours overlap with Central European Time.

Responsibilities:

• Add unit tests with pytest or Jest so new code does not lower coverage
• Write and test backend features in Python or Node.js under the guidance of a senior developer
• Pair with other engineers over screen share to work through tricky problems
• Join the daily 15-minute standup on Google Meet and post a short written update in Slack
• 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
• Build REST API endpoints and document them in Postman or Swagger

• Are able to join within 15 days
• Have a working laptop and a stable internet connection
• Can commit full time, from home, for the whole internship
• A GitHub profile with at least two projects you wrote yourself
• Own laptop with at least 8 GB RAM and a reliable internet connection
• Able to communicate clearly in written English on Slack and in pull requests
• Must be able to overlap at least 4 hours a day with the team's working hours
• Available for 30 to 40 hours a week for the full internship period

What you get out of it:

• Weekly 1:1 with your mentor to go over what went well and what to work on next
• How a production codebase is organised, deployed and monitored
• 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
