Software Engineering Intern - Remote

About us:

We run a marketplace with over 300,000 active sellers and fulfillment centres in four regions. Since 2002, the company has expanded from listings into payments, shipping and seller financing. Support shifts are shared, so engineers spend a few hours a quarter answering customer tickets.

About the role:

We need a student who can write clean code, test it and explain what it does. Prior internships are not required. We are headquartered in Dallas and have been hiring remotely since 2020. This is a remote internship. You will work with our team in Dallas, and the stipend is paid monthly in USD. Core hours overlap with US Central time, 9:00 AM to 1:00 PM CT. Communication happens mostly in Slack and short video calls.

What you'll do:

• 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
• Refactor old modules when asked, keeping behaviour the same
• Add unit tests with pytest or Jest so new code does not lower coverage
• Update the README and internal Confluence pages when you change how something works

Who can apply:

• Based in Spain for the duration of the internship
• Currently enrolled in a bachelor's or master's degree, graduating between December 2027 and June 2028
• Comfortable writing simple SQL queries (SELECT, JOIN, GROUP BY)
• Able to communicate clearly in written English on Slack and in pull requests
• Basic understanding of data structures, OOP and how HTTP requests work
• Good grasp of at least one programming language: Python, Java, JavaScript or C++

Bonus points:

• Competitive programming practice on LeetCode, Codeforces or CodeChef
