Full Job Description
We are looking for a Staff AI Engineer to lead the architectural evolution of our Inbound, Outbound, and Signal Agents. You will be responsible for turning raw intent signals into high-conversion pipeline through LLM-driven reasoning, advanced identity resolution, and seamless workflow automation.

What You'll Build
  • Autonomous Inbound Agents: Lead the development of AI agents that don't just "chat," but identify, qualify, and route leads using our proprietary Inbound Identity graph.
  • Signal Intelligence: Architect the data pipelines that ingest millions of signals to determine "Strategic/Executive Value" for our customers.
  • LLM Ops & Scalability: Build the infrastructure to move from "prompt engineering" to "agentic reasoning," ensuring our AI is reliable, cost-efficient, and fast enough for real-time web traffic.
  • Data Room Ready Engineering: Maintain rigorous documentation and clean architecture, ensuring our tech stack is a "plug-and-play" asset for our Series B due diligence.

Tech stack:
  • Backend: TypeScript, Node.js, GraphQL, tRPC
  • Infrastructure: PostgreSQL, Redis, Elasticsearch, Google Cloud Platform, Kubernetes, Docker
  • Third-party Integrations: Salesforce, Hubspot, Pipedrive, Outreach, Apollo, Slack
  • Experience with TypeScript
  • Experience with Node.js
  • Experience with React
  • Experience with PostgreSQL, Redis

Who You Are
  • The 10x Architect: You have a track record of taking AI products from 0 to 1 and then scaling them to 100. You understand that "Growth at all costs" is dead-you build for unit economic efficiency.
  • Technical Depth: Expert in Python, TypeScript, and the modern AI stack (LangChain/LlamaIndex, Vector DBs, OpenAI/Anthropic APIs).
  • Product-Minded: You don't just build features; you solve problems for our core personas-Marketing, Sales, and RevOps.
  • Lean & Mean Mindset: You are excited about the challenge of a high-performance, consolidated team and thrive in an environment where speed-to-market is the primary metric.
  • 8+ years of experience

Why Warmly?
  • Proven PMF: Our top champions are already buying for Inbound Identity. You are joining a rocket ship that already has its trajectory set.
  • Series B Readiness: We are sharpening our tools and our team to dominate the market. You will have a seat at the table as we scale the engineering org.
  • Equity & Impact: High-leverage role with significant equity upside as we prepare for our next major milestone.
