Software Engineering Intern

Our engineering group is split into roughly 60 product teams, each owning its services end to end, with on-call shared across time zones. Most engineers work remotely and come into the office one week a quarter for planning.

About the internship:

Thatchhall Labs is hiring a Software Engineering Intern for Immediately. We need a student who can write clean code, test it and explain what it does. Prior internships are not required. Remote, open to candidates across Spain. We do not have many meetings. Most updates happen in writing.

What you'll do:

• Update the README and internal Confluence pages when you change how something works.
• 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.
• Join the daily 15-minute standup on Google Meet and post a short written update in Slack.
• Add unit tests with pytest or Jest so new code does not lower coverage.

Who you are:

• Currently enrolled in a bachelor's or master's degree, graduating 2026, 2027 or 2028.
• Available for the full internship period.
• Some experience with Git, even if only on college or personal projects.
• Able to communicate clearly in written English on Slack and in pull requests.
• A GitHub profile with at least two projects you wrote yourself.

Nice to have:

• Contributions to an open source project, however small.

What you'll learn:

• Weekly 1:1 with your mentor to go over what went well and what to work on next.
• Code review on every pull request, so expect a lot of feedback on naming, tests and structure.
• How a production codebase is organised, deployed and monitored.
• Writing tests is part of the job here, and you will get good at it.

Program dates: Immediately, 6 months.

Compensation: €1,250 - €1,500/month

Perks:

• Company laptop.
• Possibility of a full-time offer.
• Flexible hours.
• Certificate of completion.
• Paid public holidays.

Duration: 6 months. Start: Immediately.
