JavaScript (Programming Language) Node.Js TypeScript Large Language Models Multi-Agent Systems Backend Virtual Agents

Job description

  • Own and continuously improve the backend systems that power all agentic AI features across the platform
  • Design, write, and maintain agents responsible for different tasks across a GTM team’s workflows, leveraging the latest agent frameworks
  • Develop and maintain backend services in Node.js that power these agents
  • Build state-of-the-art context management pipelines and manage thousands of stateful agents.
  • Ship fast and often - deploying to production frequently while maintaining high-quality standards

Requirements

  • Ownership-first mindset - you take initiative, move fast, and figure things out
  • Thrive in early-stage, high-urgency environments where speed and impact matter
  • Fully committed to working in-person 5 days/week at our SF HQ
  • Curious, self-aware, and feedback-driven - you bring energy, not ego
  • See this role as a defining chapter - not a stepping stone or side quest

What you bring:

  • Hands-on experience building and deploying LLM-powered applications or agentic AI systems in production
  • Strong backend engineering experience with Node.js and modern JavaScript/TypeScript
  • Experience designing and orchestrating multi-agent systems, including managing agent state, memory, and context across complex workflows
  • Familiarity with modern AI frameworks and providers (Braintrust, Cerebras, Langchain or similar)
  • Understanding of multi-model architectures - knowing when and how to route tasks across different LLMs for cost, speed, and quality tradeoffs
  • A track record of shipping in fast-moving, production environments

About the company

HockeyStack is building the agent infrastructure for enterprise revenue. We spent five years building the only data architecture that preserves causality across the full revenue stack - every interaction, every signal, in sequence. On top of that foundation, we built Nex-lm, a purpose-built AI engine that compiles natural language into deterministic agent workflows. The result is a platform that can extract the revenue blueprint from a company’s data, encode it into repeatable automations, and execute it across sales, marketing, and customer success - consistently, at scale.

We are not building a dashboard tool with an AI feature. We are building the operating layer that replaces the human bottleneck in enterprise revenue organizations. This is a category being defined right now, and we intend to own it.

We have raised $50M+ from Bessemer Venture Partners, General Catalyst, Y Combinator, and others.

We operate fully in-person in San Francisco. We move fast and we hire people who want to win.

Since launching late 2023, we have grown to 8-figures in ARR, process over 60 TB of revenue data monthly, and we are working with some of the largest B2B companies in the world like Microsoft, Harvey, New Relic, Collibra, etc.
