Internship overview:

Yarrowhook is hiring a Python Engineering Intern for Summer 2027. 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. We are headquartered in Lublin and have been hiring remotely since 2020. The internship is fully remote. Interns join our Lublin team on daily calls and get a named mentor. Core hours are 10:00 to 15:00 CET.

Responsibilities:

• Query and update data in PostgreSQL or MySQL, including simple migrations.
• Write and test backend features in Python or Node.js under the guidance of a senior developer.
• Join the daily 15-minute standup on Google Meet and post a short written update in Slack.
• Build REST API endpoints and document them in Postman or Swagger.
• Raise pull requests on GitHub and respond to code review comments within a day.
• Add unit tests with pytest or Jest so new code does not lower coverage.

Who you are:

• Authorized to work in the US. CPT and OPT candidates are welcome to apply.
• Available 40 hours a week for the full internship.
• Comfortable writing simple SQL queries (SELECT, JOIN, GROUP BY)
• Basic understanding of data structures, OOP and how HTTP requests work.
• Some experience with Git, even if only on college or personal projects.
• Good grasp of at least one programming language: Python, Java, JavaScript or C++.

Nice to have:

• Contributions to an open source project, however small.

What you'll learn:

• How a production codebase is organised, deployed and monitored.
• Certificate and letter of recommendation on completion, plus a pre-placement offer for strong performers.
• You will ship at least one feature that real users touch before the internship ends.
• Weekly 1:1 with your mentor to go over what went well and what to work on next.

Program dates: Summer 2027, 10 weeks.

Pay: $42.00-$48.00/hr

Perks:

• Final presentation to leadership.
• Company laptop.
• Intern events and speaker sessions (virtual)
• Paid sick time.

Duration: 10 weeks. Start: Summer 2027.
