Backend Engineering Intern

About CM Data:

Our main product is a payroll and timekeeping app for hourly workforces, sold by subscription and supported from Columbus. Most engineers work remotely and come into the office one week a quarter for planning.

Overview:

We need a student who can write clean code, test it and explain what it does. Prior internships are not required. Remote within the US. The team meets in Columbus once a quarter, travel covered. Day-to-day communication is in Slack and Google Meet.

What you'll do:

• Query and update data in PostgreSQL or MySQL, including simple migrations.
• Raise pull requests on GitHub and respond to code review comments within a day.
• Write and test backend features in Python or Node.js under the guidance of a senior developer.
• Refactor old modules when asked, keeping behaviour the same.
• Add unit tests with pytest or Jest so new code does not lower coverage.
• Pair with other engineers over screen share to work through tricky problems.
• Profile slow endpoints and suggest fixes, such as adding an index or caching a result.
• Present a short demo of your work to the team every two weeks.

Who can apply:

• Based in the US for the duration of the internship.
• Available 40 hours a week for the full internship.
• 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++.
• A GitHub profile with at least two projects you wrote yourself.
• Able to communicate clearly in written English on Slack and in pull requests.

Preferred:

• Competitive programming practice on LeetCode, Codeforces or CodeChef.
• Contributions to an open source project, however small.
• Knowledge of Linux command line basics.

What you get out of it:

• 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.
