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 into 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.
