Software Developer Intern

Our product started as a side project in 2020 and now has a few hundred paying customers, mostly in Arizona. Profitable, no outside investors, and no plans to take any. We grow when customers pay us. On-call rotates weekly and pays a flat stipend whether or not the pager goes off.

Overview

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. Remote within the US. The team meets in Phoenix once a quarter, travel covered. Few meetings, lots of written updates.

What you'll do

• Profile slow endpoints and suggest fixes, such as adding an index or caching a result
• 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
• Write and test backend features in Python or Node.js under the guidance of a senior developer
• Query and update data in PostgreSQL or MySQL, including simple migrations

Who can apply

• Based in the US for the duration of the internship
• Currently enrolled in a bachelor's or master's program, graduating 2026, 2027 or 2028
• Authorized to work in the US. CPT and OPT candidates are welcome to apply
• 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++
• Comfortable writing simple SQL queries (SELECT, JOIN, GROUP BY)

Bonus points

• Familiarity with Django, Flask, FastAPI or Express
• Exposure to Docker or a cloud platform such as AWS or GCP

What you get out of it

• How a production codebase is organised, deployed and monitored
• Certificate and letter of recommendation on completion, plus a pre-placement offer for strong performers
• Writing tests is part of the job here, and you will get good at it
• Code review on every pull request, so expect a lot of feedback on naming, tests and structure
