Software Developer Placement Student

About Bellwether Labs:

We operate a subscription e-commerce site selling coffee, tea and brewing gear, shipped from our own warehouse. Sellers use the platform to list used outdoor gear, and we handle payments, shipping labels and buyer protection.

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. The internship is fully remote. Interns join our Stamford team on daily calls and get a named mentor. Expect to work a schedule that overlaps with US Eastern business hours until about noon ET.

Responsibilities:

• Write and test backend features in Python or Node.js under the guidance of a senior developer
• Build REST API endpoints and document them in Postman or Swagger
• Add unit tests with pytest or Jest so new code does not lower coverage
• 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
• Debug failing builds in the GitHub Actions pipeline and note what caused them
• Refactor old modules when asked, keeping behaviour the same
• Fix bugs from the Jira backlog, starting with small, well-defined tickets

• Based in Slovakia for the duration of the internship
• Currently enrolled in a bachelor's or master's degree, graduating 2026, 2027 or 2028
• Available for the full internship period
• Eligible to work in Slovakia
• A GitHub profile with at least two projects you wrote yourself
• Some experience with Git, even if only on college or personal projects
• Able to communicate clearly in written English on Slack and in pull requests
• Basic understanding of data structures, OOP and how HTTP requests work
• Comfortable writing simple SQL queries (SELECT, JOIN, GROUP BY)
• Available for 30 to 40 hours a week for the full internship period
