Software Engineer Intern

About Díaz Systems:

Profitable, no outside investors, and no plans to take any. We grow when customers pay us. Founded in 1997, we now have 21 employees. We keep recurring meetings to Tuesdays and Thursdays where we can.

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. You can work from home anywhere in Argentina. We have no office requirement. Normal working hours, Monday to Friday. Strong written English is important, since much of our work is async.

What you'll do:

Raise pull requests on GitHub and respond to code review comments within a day. Write and test backend features in Python or Node.js under the guidance of a senior developer. Fix bugs from the Jira backlog, starting with small, well-defined tickets. Query and update data in PostgreSQL or MySQL, including simple migrations. Present a short demo of your work to the team every two weeks. 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.

What we're looking for:

Available for the full internship period. Based in Argentina for the duration of the internship. Currently enrolled in a bachelor's or master's degree, graduating between December 2027 and June 2028. Basic understanding of data structures, OOP and how HTTP requests work. Own laptop with at least 8 GB RAM and a reliable internet connection. 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. A GitHub profile with at least two projects you wrote yourself. Some experience with Git, even if only on college or personal projects.

Bonus points:

Contributions to an open source project, however small. Competitive programming practice on LeetCode, Codeforces or CodeChef. Familiarity with Django, Flask, FastAPI or Express.
