Backend Engineering Intern

About us:

Two developers, a designer and a support lead make up most of the company, so everyone touches the product. Customers who call us usually reach someone who wrote the code they are asking about. On-call rotates weekly and pays a flat stipend whether or not the pager goes off.

Overview:

We need a student who can write clean code, test it and explain what it does. Prior internships are not required. You can work from home anywhere in the US. We have no office requirement. Hours are flexible, with one short team call each morning. We use Slack, Notion and Google Meet. Cameras on for team calls.

Day to day:

Update the README and internal Confluence pages when you change how something works. Refactor old modules when asked, keeping behaviour the same. Debug failing builds in the GitHub Actions pipeline and note what caused them. Build REST API endpoints and document them in Postman or Swagger. Query and update data in PostgreSQL or MySQL, including simple migrations. Present a short demo of your work to the team every two weeks. Pair with other engineers over screen share to work through tricky problems. Write and test backend features in Python or Node.js under the guidance of a senior developer.

Requirements:

Available 40 hours a week for the full internship. Based in the US for the duration of the internship. 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. Some experience with Git, even if only on college or personal projects.

Nice to have:

Competitive programming practice on LeetCode, Codeforces or CodeChef. Familiarity with Django, Flask, FastAPI or Express.

What you'll learn:

Weekly 1:1 with your mentor to go over what went well and what to work on next. How a production codebase is organised, deployed and monitored. Certificate and letter of recommendation on completion, plus a pre-placement offer for strong performers.
