Software Engineering Intern - Remote

Small accounting firms in Guanajuato use our engagement letter and e-signature tool, and most heard about us from a colleague.

About the role:

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. Remote position. Most of the team is in León, but nobody is required to come in. Normal working hours, Monday to Friday. We use Slack, Notion and Google Meet. Cameras on for team calls.

Responsibilities:

• Raise pull requests on GitHub and respond to code review comments within a day.
• 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.
• Join the daily 15-minute standup on Google Meet and post a short written update in Slack.
• Profile slow endpoints and suggest fixes, such as adding an index or caching a result.
• Refactor old modules when asked, keeping behaviour the same.
• Update the README and internal Confluence pages when you change how something works.
• Fix bugs from the Jira backlog, starting with small, well-defined tickets.

What we're looking for:

• Based in Mexico for the duration of the internship.
• Available for the full internship period.
• Must be able to overlap at least 4 hours a day with the team's working hours.
• Basic understanding of data structures, OOP and how HTTP requests work.
• 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.

What you'll learn:

• Certificate and letter of recommendation on completion, plus a pre-placement offer for strong performers.
• Writing tests is part of the job here, and you will get good at it.

Start date: Mar 2027
