Job Description
Founding Software Engineer architecting and building customer intelligence solutions for e-commerce startup OuterSignal. Joining a high-performing team in a fast-paced, dynamic environment.
Responsibilities:
- 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
