Software Engineering Intern

Harborlane Labs employs 440 people across engineering hubs in London and three other locations, building ERP software for mid-market manufacturers.

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. This role is fully remote within the UK. Hours are flexible, with one short team call each morning. Communication happens mostly in Slack and short video calls.

RESPONSIBILITIES

• Add unit tests with pytest or Jest so new code does not lower coverage.
• Fix bugs from the Jira backlog, starting with small, well-defined tickets.
• Build REST API endpoints and document them in Postman or Swagger.
• Refactor old modules when asked, keeping behaviour the same.
• Profile slow endpoints and suggest fixes, such as adding an index or caching a result.
• Join the daily 15-minute standup on Google Meet and post a short written update in Slack.

REQUIREMENTS

• Based in the UK for the duration of the internship.
• Eligible to work in the UK.
• Currently enrolled in a bachelor's or master's degree, graduating 2027 or 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.
• A GitHub profile with at least two projects you wrote yourself.
• Able to communicate clearly in written English on Slack and in pull requests.
• Good grasp of at least one programming language: Python, Java, JavaScript or C++.
• 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.
• Certificate and letter of recommendation on completion, plus a pre-placement offer for strong performers.
• 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.
