Software Engineer Intern

ABOUT US

No call centre and no offshore help desk. When clients call, one of us picks up. We support about 60 local businesses, most within 30 minutes of the office. Founded in 2017, we now have 28 employees.

THE INTERNSHIP

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 within Spain. The team meets in Bilbao once a quarter, travel covered. Communication happens mostly in Slack and short video calls.

DAY TO DAY

• Refactor old modules when asked, keeping behaviour the same.
• Add unit tests with pytest or Jest so new code does not lower coverage.
• 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.
• Present a short demo of your work to the team every two weeks.
• 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.

REQUIREMENTS

• Eligible to work in Spain.
• 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)
• Must be able to overlap at least 4 hours a day with the team's working hours.
• Good grasp of at least one programming language: Python, Java, JavaScript or C++.
