Software Engineering Intern

Our main product is a payroll and timekeeping app for hourly workforces, sold by subscription and supported from New York City. Customers use our platform to manage equipment rentals: reservations, check-out, damage photos, invoicing and QuickBooks sync. Laptops are MacBook Pros, and you pick your own editor.

Overview:

Our Integrations team is five engineers working fully remote across two time zones. The intern picks up small backend tickets first and moves to bigger features once comfortable. We are headquartered in New York City and have been hiring remotely since 2020. You will intern remotely with our team in New York City. We have hosted remote interns from several countries before. Core hours are 9:00 AM to 1:00 PM US Eastern. Strong written English is important, since much of our work is async.

What you'll do:

• Update the README and internal Confluence pages when you change how something works
• Raise pull requests on GitHub and respond to code review comments within a day
• Refactor old modules when asked, keeping behaviour the same
• Add unit tests with pytest or Jest so new code does not lower coverage
• Write and test backend features in Python or Node.js under the guidance of a senior developer
• 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
• Fix bugs from the Jira backlog, starting with small, well-defined tickets

Requirements:

• Currently enrolled in a bachelor's or master's degree, graduating 2028
• Based in Germany for the duration of the internship
• Comfortable writing simple SQL queries (SELECT, JOIN, GROUP BY)
• Some experience with Git, even if only on college or personal projects
• A GitHub profile with at least two projects you wrote yourself
• Basic understanding of data structures, OOP and how HTTP requests work
• 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++

What you get out of it:

• Code review on every pull request, so expect a lot of feedback on naming, tests and structure
• Weekly 1:1 with your mentor to go over what went well and what to work on next
• 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
