Summer Software Engineering Intern

About Keystone Digital

Our main product is a payroll and timekeeping app for hourly workforces, sold by subscription and supported from Irvine.

Overview

We need a student who can write clean code, test it and explain what it does. Prior internships are not required. We are headquartered in Irvine and have been hiring remotely since 2020. The internship is fully remote. Interns join our Irvine team on daily calls and get a named mentor. You will need at least 3 hours of overlap with US Pacific time.

Day to day

• 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.
• 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.
• Build REST API endpoints and document them in Postman or Swagger.
• Fix bugs from the Jira backlog, starting with small, well-defined tickets.
• Debug failing builds in the GitHub Actions pipeline and note what caused them.

Requirements

• Eligible to work in France.
• Currently enrolled in a bachelor's or master's degree, graduating 2026, 2027 or 2028.
• Available for the full internship period.
• Based in France for the duration of the internship.
• Comfortable writing simple SQL queries (SELECT, JOIN, GROUP BY)
• Own laptop with at least 8 GB RAM and a reliable internet connection.
• Able to communicate clearly in written English on Slack and in pull requests.

Nice to have

• Any previous internship, hackathon or freelance coding work.
• Contributions to an open source project, however small.
• Knowledge of Linux command line basics.

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.
