About Hazel

Hazel is the AI coworker for consumer brands. We connect to a brand's live data — Shopify, Amazon, Klaviyo, warehouse systems — and turn it into an AI teammate that can answer business questions, run multi-step research, and surface opportunities that would take a human hours to find. Think: "what's driving the drop in repeat purchase rate?" answered in minutes, with citations, from real data.

We're a small, venture-backed team and already working with great brands you'd recognize. We're hiring our next founding engineer to build alongside us.

The Role

You'll own major pieces of the product end-to-end — from the conversational AI interface to the data integrations that power it. You'll work directly with the founders and customers, ship fast, and have real influence over what we build and how.

What You'll Do

Build AI agent workflows — streaming LLM responses, multi-step research with tool use, human-in-the-loop approvals.
Ship product features across the full stack: React, Typescript / Golang services
Design and extend integrations with platforms like Shopify, Amazon Ads, and Stripe
Define service contracts with protobuf and build the infrastructure that connects our services
Work directly with customers to understand what they need and translate that into product

About You

Strong software engineer with meaningful startup or high-growth experience
You've shipped end-to-end products — not just features within a larger system
High agency — you figure things out, make tradeoffs, and move fast without waiting for permission
Deep TypeScript experience; comfortable picking up Python or Go as needed
Solid understanding of database design and query performance (Postgres, DuckDB)
You care about getting the interface right, not just the API

Bonus Points

Experience building with LLMs — prompt engineering, tool use, retrieval, agent architectures, skills, mcp, etc.
E-commerce, consumer, or retail domain knowledge
Familiarity with workflow orchestration (Temporal, etc.)

Our Stack

TypeScript, React, Tailwind css, Vercel, Go, Python, Protobuf/Buf, PostgreSQL, Temporal, DuckDB/MotherDuck, Render

Why Join Hazel

You'll build AI products used daily by operators at real brands
You own features end-to-end; your work ships directly to customers
Novel technical challenges at the intersection of LLMs, live data, and business decision-making
Lean team, big ambition, real ownership — both in equity and in how you shape what we're building
