## Description

**About OuterSignal**
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.

**What You’ll Do:**

- 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

**Who You Are:**

- 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.Why Join Now:**

- **Early seat**: This is shaping the DNA of OuterSignal’s engineering org.

- **Massive upside**: Meaningful equity in a venture-backed company defining a new SaaS category

- **High leverage work**: You’ll see your code directly impact customers, revenue, and growth

- **Big surface area**: From AI pipelines to Shopify apps to RAG/vector search infra, you’ll touch it all

- **Right moment**: We’re past prototype, real brands already rely on us and have PMF, but the ceiling is wide open
