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
