Senior Product Engineer

Fonzi is an AI recruiting company.

Every week, hiring managers at 100+ pre-vetted startups in NYC and San Francisco review a curated group of engineers.

We work with early stage companies backed by investors like A16z, Sequoia Capital, General Catalyst, Y Combinator and more.

The engineers who do best on Fonzi:

• Have built AI-powered products end-to-end, not just prototypes, but systems handling real users
• Can talk fluently about retrieval, memory, agent frameworks, context engineering, eval pipelines and anything else at the cutting edge
• Combine strong software engineering fundamentals with deep awareness of what's happening at the frontier of LLMs and agentic systems
• Thrive in startup environments where the problem is ambiguous and the team is small
• Have 2-8 years of experience, ideally with experience at at least one high-growth company

Compensation

• $200,000 – $400,000+ base salary depending on experience and role. Many positions include meaningful equity at pre-seed through Series B stage companies.

The Interview Process (Typical)

• Screening conversation looking for communication skills, cultural fit, genuine curiosity about AI
• Technical deep-dive talks on architecture thinking, how you'd design an AI system for a real problem
• Coding or pairing sessions building
