About the job
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)
