Engineering Intern
Ship real code with a small engineering team. Pick your track: core app development, app infrastructure, or growth.
About the role
Our app has 100,000+ downloads and a small team behind it. An intern here ships to production.
You pick one of three tracks based on what you want to learn. You get a mentor on the engineering team, a real backlog, and code review on everything you write.

App Infrastructure
Work on what keeps the app fast and stable: backend services, monitoring, release pipeline, and analytics events.
Growth
Work on the website and purchase funnel in React, Tailwind, and the Shopify Storefront API. Run A/B tests, fix tracking and attribution, and build internal tools with AI.
