About the role

  • 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

Requirements

  • 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.
Benefits
  • 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
