Founding AI Engineer – San Francisco (Onsite)

$120k–$250k + 0.1%–0.4% equity

I’m partnering with an early-stage AI team (<10 people) that’s building next-generation agentic AI systems. They’re looking for a Founding AI Engineer to join onsite in San Francisco, working directly with the cofounders to ship AI products that feel human, reason reliably, and scale.

Role Highlights:

  • End-to-end ownership of AI systems: retrieval, reasoning, tool use, and safety
  • Ship agentic matchmaking & chat features from research to production
  • Build prompt & model evaluation pipelines to support fast iteration
  • Optimise AI systems for latency, consistency, and human-likeness
  • Design context-engineering pipelines and observability dashboards

What they’re looking for:

  • 2–4+ years in AI/LLM development or a standout portfolio of AI agents
  • Strong TypeScript & Python skills with solid CS fundamentals
  • Experience with multiple LLM providers, tool-calling, and RAG pipelines
  • Practical prompt engineering & evaluation experience
  • Builder’s mindset: thrives with ambiguity, ships quickly, and cares about UX

If you’re interested in this high-ownership, early-stage role, please apply via LinkedIn or reach out directly.
