Original job description

About OuterSignal

We are building the customer intelligence and personalization layer for consumer businesses. Every business knows when an order comes in or a user signs up, but they only see 5% of the real story.

We show them the other 95%: not just who’s buying, but who that person actually is. That includes the execs, influencers, journalists, retail buyers, investors, and everyday customers who become a brand’s best evangelists. Our platform enriches every customer in real time with professional and personal signals, builds 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 customer intelligence, backed by a world-class investor base.

  The Opportunity

We’re hiring a Senior Software Engineer to architect and own the core systems behind OuterSignal: the APIs, queues, and LLM pipelines that enrich millions of orders in real time.

The surface area is big, from AI pipelines to Shopify apps to RAG and vector search infrastructure, and you’ll see your code directly impact customers, revenue, and growth. We’re past prototype with strong product-market fit, and the ceiling is wide open.

You’ll work directly with the founding team on the roadmap and product direction, and help shape how we hire and build as the engineering team grows.

 

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, and Vercel

  • Integrate vector databases and RAG pipelines to make customer profiles smarter, faster, and searchable in real time

  • Ship features end to end: APIs, dashboards, and integrations (Shopify, Klaviyo, Slack, Zapier, Gorgias)

  • Keep us ahead on privacy and compliance

  • Work directly with the founding team on the roadmap, product direction, and hiring future engineers

 

What We’re Looking For

  • 5+ years of engineering experience, ideally with backend infrastructure and distributed systems

  • Experience at 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 and scaling Postgres

  • Bonus: experience building 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.

 

What We Offer

  • Impact: Join at the ground floor where your work directly influences company trajectory

  • Growth: Real brands already rely on us and we’re scaling fast, which means exceptional learning opportunities and room to grow with the company

  • Upside: Meaningful equity in a venture-backed company defining a new category

  • Team: Work directly with the founders and experienced operators

  • Ownership: An early seat shaping the DNA of OuterSignal’s engineering org

  How to Apply

Submit your resume along with responses to the application questions. We review applications on a rolling basis and will reach out to qualified candidates to discuss potential opportunities.

OuterSignal is an equal opportunity employer. We celebrate diversity and are committed to creating an inclusive environment for all employees.
