# Founding Engineer

> Join Henry Labs in NYC as a founding engineer

* 📍 **Location: New York City (in-person)**
* 💰 **Salary: \$120,000 - \$280,000 + 0.5% - 2% equity**
* 💼 **Years of experience: 1+**
* 🛠️ **Skills: TypeScript, Bun, Postgres, Playwright, SDKs, API design, React**

## About Henry Labs

We're building the **operating system for agentic commerce**: the layer that turns a user's intent to buy into a completed order on any merchant site.

We enable a **true universal cart** and **one-click checkout anywhere on the Internet** - so users can add items from multiple merchants in one place and buy seamlessly, without bouncing through different tabs, logins, and carts.

Platforms like Pinterest, Instagram, TikTok, and AI chatbots/shopping experiences already handle product discovery. What's missing is reliably executing checkout across thousands of ecommerce sites without direct integrations.

That's where we come in. Our agent **executes checkout on behalf of users**, then returns order confirmation back to the app.

Imagine being able to **buy an entire outfit you see on Pinterest in one click** - sizes, colors, shipping, and payment handled instantly - without bouncing through 6 different sites and carts.

That's just one example of what we enable. Companies use us to embed shopping natively so that users can **buy what they want, the moment they discover it**.

If you're excited about building agents and infrastructure that **revolutionizes how the world buys online**, we'd love to talk!

## About the role

As **Founding Engineer** at Henry Labs, you'll architect and build the core systems that power our AI agent platform end-to-end. You'll own critical infrastructure from conception to production, working with bleeding edge tech that needs to be both reliable and low latency. You'll also play a foundational role in how we build Henry Labs's culture.

## What you'll do

* Design, develop, and scale new **product infrastructure, developer tools, and APIs**
* Set direction for **critical technical surface areas**, enabling us to stay ahead of rapid growth
* Build reliable, scalable backend systems that handle payment and checkout complexity
* Shape Henry Labs's hiring decisions and **culture** as we grow

## What we're looking for

* **1+ years of experience** building production software
* Experience with **TypeScript, React, Supabase/Postgres, and API/SDK design**
* Interest or experience in **browser automation, Playwright, or similar tooling**
* Interest or experience in **fintech, payments, e-commerce, or developer tools**
* **Technical excellence:** as a developer tool, our technical decisions are the product, and the details matter a lot.
* **Low ego, high impact:** you care more about building something meaningful than who gets credit
* **Start-up ready:** early stage sometimes means figuring it out as we go, and that energizes rather than drains you
* **Excited to crush it:** we're moving fast and looking for people excited about high velocity, high impact work, and having fun along the way.

## What you can expect at Henry Labs

* **Industry-competitive salary**
* **Above market equity** in an early-stage company
