About the role

  • This is a backend-focused software engineering role specializing in applying ML/AI to user-facing products.
  • The evolution of this role will include inference serving, fine-tuning, and synthetic dataset generation.

Responsibilities

  • Build and improve production AI/data pipelines that run across LLMs, APIs, databases, and workflow systems like Temporal, Postgres, ClickHouse, and Kubernetes.
  • Design evals and build Jupyter notebooks that help us measure model behavior, data quality, extraction accuracy, and end-to-end customer impact.
  • Build observability into AI workflows so we can understand cost, latency, reliability, and quality.
  • Integrate with fast-changing research and AI APIs, understand their behavior deeply, and build robust abstractions around them.
  • prompt chaining, eval design, research APIs, model routing, and prod orchestration.

Requirements

  • You are extremely AI-fluent and actively use modern AI tools to move faster.
  • You have strong first-principles thinking and can turn ambiguous problems into hypotheses, experiments, and shipped systems.
  • You have good judgment and taste: you simplify aggressively, avoid unnecessary complexity, and care about maintainability.

Nice to have

  • You have experience with PyTorch, Hugging Face, vLLM, Ray, MLflow, RAG, fine-tuning & RL, inference serving, and/or model evaluation systems.

Benefits

  • Meaningful equity in a venture-backed company defining a new category in commerce intelligence.
  • Bonus: You have experience with PyTorch, Hugging Face, vLLM, Ray, MLflow, RAG, fine-tuning & RL, inference serving, and/or model evaluation systems.

Company info

  • 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 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 e-commerce customer intelligence, backed by a world-class investor base.
  • You'll work on production AI that directly affects customers, data quality, and revenue - not demos or toy agents.
