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.
