Software Engineering Intern

Customers use our platform to manage equipment rentals: reservations, check-out, damage photos, invoicing and QuickBooks sync. Clients range from single-location retailers to franchise groups with hundreds of stores, all running our point-of-sale and loyalty software.

The internship:

This is a hands-on coding internship. Most of the work is in Python and Node.js, with some SQL and a bit of shell scripting. We are headquartered in London and have been hiring remotely since 2020. You will intern remotely with our team in London. We have hosted remote interns from several countries before. You will need to be available during UK office hours, at least until 3:00 PM GMT. Good written English matters here, since most updates are written.

Day to day:

• Build REST API endpoints and document them in Postman or Swagger.
• Fix bugs from the Jira backlog, starting with small, well-defined tickets.
• Profile slow endpoints and suggest fixes, such as adding an index or caching a result.
• Update the README and internal Confluence pages when you change how something works.
• Add unit tests with pytest or Jest so new code does not lower coverage.
• Query and update data in PostgreSQL or MySQL, including simple migrations.
• Present a short demo of your work to the team every two weeks.

Who can apply:

• Currently enrolled in a bachelor's or master's degree, graduating 2028.
• Available for the full internship period.
• Able to communicate clearly in written English on Slack and in pull requests.
• Good grasp of at least one programming language: Python, Java, JavaScript or C++.
• Own laptop with at least 8 GB RAM and a reliable internet connection.
• Basic understanding of data structures, OOP and how HTTP requests work.
• A GitHub profile with at least two projects you wrote yourself.
