Software Developer Placement Student

Who we are

More than 9,000 organisations use our HR and payroll suite, from regional hospitals to school districts.

About the role

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 Warsaw team on daily calls and get a named mentor. Working hours overlap with Central European Time. You will need a reliable internet connection and a quiet place to work.

Responsibilities

• Join the daily 15-minute standup on Google Meet and post a short written update in Slack.
• Present a short demo of your work to the team every two weeks.
• Refactor old modules when asked, keeping behaviour the same.
• Debug failing builds in the GitHub Actions pipeline and note what caused them.
• Write and test backend features in Python or Node.js under the guidance of a senior developer.
• Query and update data in PostgreSQL or MySQL, including simple migrations.
• Pair with other engineers over screen share to work through tricky problems.
• Add unit tests with pytest or Jest so new code does not lower coverage.

Requirements

• Based in Romania for the duration of the internship.
• Currently enrolled in a bachelor's or master's degree, graduating 2026 or 2027.
• Good grasp of at least one programming language: Python, Java, JavaScript or C++.
• Comfortable writing simple SQL queries (SELECT, JOIN, GROUP BY)
• Able to communicate clearly in written English on Slack and in pull requests.

Bonus points

• Any previous internship, hackathon or freelance coding work.
