Data Scientist

🚀 Founding AI Engineer (Berkley, Onsite)

We’re building the first fully agentic social platform, starting with dating. Our AI understands user preferences, finds compatible matches, and even sets up real-life dates. The product has already gone viral across campuses, facilitated tens of thousands of real dates, and is backed by top-tier VCs and Google.

This is an early role on a <10 person team, working directly with the cofounders.

What you’ll do:

• Own agentic matchmaking end-to-end: retrieval, reasoning, tool use, safety — from research to production
• Build and evaluate prompts, models, and policies (offline + online, A/B testing)
• Design chat agents that feel fast, reliable, and human
• Build context pipelines (RAG, memory, summarization, grounding)
• Stand up agent observability: traces, costs, failures, hallucinations
• Ship internal tools and SDKs used by engineers — and by other AIs

What we’re looking for:

• 2–4+ years of experience or an exceptional portfolio of LLM/agent products
• Strong CS fundamentals and clean, maintainable code
• TypeScript + Python
• Experience with multiple LLM providers, tool/function calling, and fallbacks
• Hands-on RAG and prompt engineering with strong intuition for failure modes
• Comfort defining metrics (accuracy, latency, cost, safety) and iterating quickly
• Batchelors degree in Computer Science or other related field

Bonus points!!
