Hazel is the AI coworker for consumer brands. We connect to a brand's live data—Shopify, Klaviyo, Amazon, Meta, and many others—and turn it into actionable insights that operators can use in real time. Hazel can also take action directly in the connected systems, running full playbooks autonomously with human-in-the-loop safeguards. We are backed by investors and serve prominent brands; you’ll join a small, senior engineering team working directly with the founders.

What you’ll work on In your first 60 days, you’ll extend Hazel’s action layer by writing back into the systems she connects to—e.g., creating product bundles in Shopify, launching A/B tests in Klaviyo, and building the human-in-the-loop scaffolding that keeps everything safe. Beyond that: - Full-stack product features across TypeScript/React + Go services - AI agent workflows: streaming LLM responses, multi-step tool use, approvals - Integrations across Shopify, Klaviyo, Meta, Amazon, and more, reading and writing data You’ll work directly with the founders and customers. Code you ship today will be in front of operators tomorrow.

Who we’re looking for - You’ve shipped a production LLM feature to real users - You’ve owned an API at scale: query optimization, schema design, selecting the right tool for the workload - Strong TypeScript experience - You use coding agents to do the work of a larger team, and you can explain where they helped and where they hindered - You care deeply about product ergonomics and UX - Former or aspiring founders

This isn’t for you if: - You want product specs handed to you; your
