Sr. AI Engineer

Greylock Partners | San Francisco, California, United States | 1w ago
full-time | on-site | senior | 3–5 years
skills: backend software engineering, applied ai, llm, rag, agentic applications, async processing, data models

One of our early-stage investments is looking to bring on a Senior AI Engineer to join the founding technical team.

We’re looking for someone who has built agentic applications in production at a company with a strong engineering bar. This isn’t a “tinkering only” role. The ideal candidate is a strong backend software engineer who has moved into applied AI and enjoys building real products with LLMs.

What you’ll do

  • Build and ship agentic applications and AI-powered workflows used directly by customers
  • Design and productionize RAG pipelines and other modern LLM systems
  • Own backend services that support AI features, including async processing, integrations, and data access within customer environments
  • Collaborate closely with product and infrastructure engineers to turn ambiguous problems into reliable systems

What we’re looking for

  • Typically, 5+ years of cumulative software engineering experience (or exceptionally strong with 3+ years)
  • 1+ years building agentic applications in production (preferred)
  • Alternatively, 1+ years building production RAG pipelines or other modern applied AI systems
  • Strong backend engineering foundation: designing services, data models, and async processing systems
  • Experience in environments with a high engineering bar for production AI systems

Not a fit if your background is primarily

  • Classic ML research or modeling work
  • ML infrastructure / platform roles
  • Pre-training focused experience

Nice to have

  • Enterprise integrations and working in customer environments
  • Workflow orchestration / job processing frameworks
  • Building internal tools, developer platforms, or UI-driven software

What makes this compelling

  • Early, high-impact role on a small founding team
  • Opportunity to shape core AI architecture and product direction
  • Strong peers, fast iteration, and real customer problems
  • Competitive compensation and meaningful equity

Team Size: < 10

Work Culture: 5 days/week in SF Office
