Internship — Fullstack Engineer (Add-to-Cart)
**Add-to-Cart is our moment of truth.**
It’s also one of the biggest sources of incidents and operational load today — and fixing it is a direct lever on conversion and customer trust.
Role
As a Fullstack Engineering Intern, you will directly report to the CTO \& Co-Founder and you will:
1.
**Own a “core conversion” topic:**
make our
**Add-to-Cart**

2.
**Be accountable for measurable outcomes:**
reduce Add-to-Cart incidents and shorten time-to-resolution, with clear tracking of impact.
3.
**Think business-first:**
partner with Ops, Account Management, and Engineering to prioritize what best protects customer satisfaction and revenue.
4.
**Experience the startup pace:**
work day-to-day in an early-stage team that moves fast and ships often.
Mission
The product evolves quickly, so your scope will adapt. Concrete examples on Add-to-Cart include:
* **Stabilize Add-to-Cart “deeply”**
Identify recurring patterns (intermittent failures, multi-BU setups, sync issues, variants, refresh/state bugs, client-specific configs).
* Improve reproducibility and ticket quality (what we always need to diagnose fast).
* Propose and implement targeted fixes on the highest-impact root causes.
* **Build the AI agent that will replace you**
Build an AI agent capable of automatically:
* diagnose the add-to-cart issue on our customer website
* propose a fix in our code
* test the fix
What success looks like (8–12 weeks)
* A
**visible decrease**
in Add-to-Cart incidents and/or mean time to resolution.
