Senior Software Engineer

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 serve 150+ brands and are growing 50% month-over-month - all within our first 6 months of operation. 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
