Backend Development Intern

Annual releases gave way to two-week sprints years ago, and the platform now handles over 200 million API calls a day. Our engineering group is split into roughly 60 product teams, each owning its services end to end, with on-call shared across time zones. We started in 1995 and have grown to about 2,700 people.

About the role:

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. Our headquarters is in Madrid, and about a third of the team works remotely from other countries. This is a remote internship. You will work with our team in Madrid, and the stipend is paid monthly in USD. Working hours overlap with Central European Time. You need a reliable internet connection and somewhere quiet to work.

What you'll do:

• 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.
• Build REST API endpoints and document them in Postman or Swagger.
• 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.
• Fix bugs from the Jira backlog, starting with small, well-defined tickets.

What we're looking for:

• Final-year students or recent graduates of BSc in CSE, EEE, BBA or a related subject.
• Own laptop and a reliable internet connection.
• Based anywhere in Bangladesh.
• Available for at least 30 hours a week from home.
• Good grasp of at least one programming language: Python, Java, JavaScript or C++.
• Able to communicate clearly in written English on Slack and in pull requests.
• Comfortable writing simple SQL queries (SELECT, JOIN, GROUP BY)
• Some experience with Git, even if only on college or personal projects.
• Available for 30 to 40 hours a week for the full internship period.
• Basic understanding of data structures, OOP and how HTTP requests work.

Bonus points:

• Competitive programming practice on LeetCode, Codeforces or CodeChef.
• Contributions to an open source project, however small.

What you get out of it:

• Weekly 1:1 with your mentor to go over what went well and what to work on next.
• Writing tests is part of the job here, and you will get good at it.
• Certificate and letter of recommendation on completion, plus a pre-placement offer for strong performers.
