## About the Role

* 5+ years engineering experience, ideally with backend infra + distributed systems
 * Experience in a fast-paced startup or willingness to dive in to a dynamic, changing environment
 * Fluent in JS/TS (Node), with some Python/ML exposure a plus
 * Experience with vector databases (Pinecone, Weaviate, pgvector, etc.) and RAG architectures
 * Comfortable designing schemas + scaling Postgres
 * Bonus if you've built around LLMs, Shopify apps, or data-privacy frameworks
 * Most importantly: you want ownership. You like to build quickly, solve "figure-it-out" problems, and aren't afraid of messy early-stage work.

## Description

We are building the customer intelligence layer for commerce. Brands know when an order comes in, but they only see ~5% of the real story. We show them the other 95%: not just who bought, but who that person is - the execs, influencers, journalists, retail buyers, investors, and everyday customers who become a brand's best evangelists. Our platform enriches every order in real time with professional + personal signals, unlocks personas, and powers everything from surprise-and-delight outreach to smarter email flows, analytics, and BD leads. We're a small, high-performing team building the category-defining platform for e-commerce customer intelligence, backed by a world-class investor base., * Architect and own core systems that process millions of orders across APIs and LLM pipelines

 * Build queue-based microservices using Redis, Node.js, Typescript, Postgres, Docker/K8s, Vercel
 * Integrate vector databases + RAG pipelines to make customer profiles smarter, faster, and searchable in real time
 * Ship features end-to-end: APIs, dashboards, integrations (Shopify, Klaviyo, Slack, Zapier, Gorgias)
 * Keep us ahead on privacy & compliance
 * Work directly with Founding Team on roadmap, product direction, and hiring future engineers
