Software Engineering Intern

Who we are

Small businesses use our merchant services for card processing, POS terminals and next-day funding. Our advisors handle retirement planning, investment management and estate coordination for about 900 households.

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. The internship is fully remote. Interns join our Montpellier team on daily calls and get a named mentor. Working hours overlap with Central European Time.

Day to day

• 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.
• Query and update data in PostgreSQL or MySQL, including simple migrations.
• Pair with other engineers over screen share to work through tricky problems.
• Raise pull requests on GitHub and respond to code review comments within a day.
• Profile slow endpoints and suggest fixes, such as adding an index or caching a result.
• Fix bugs from the Jira backlog, starting with small, well-defined tickets.

Who can apply

• Based in Mexico for the duration of the internship.
• Currently enrolled in a bachelor's or master's degree, graduating 2027 or 2028.
• Available for 30 to 40 hours a week for the full internship period.
• Good grasp of at least one programming language: Python, Java, JavaScript or C++.
• Must be able to overlap at least 4 hours a day with the team's working hours.
• Own laptop with at least 8 GB RAM and a reliable internet connection.

What you get out of it

• You will ship at least one feature that real users touch before the internship ends.
• How a production codebase is organised, deployed and monitored.
• Code review on every pull request, so expect a lot of feedback on naming, tests and structure.
