Position
Generative AI Engineer
Full-time, On-site
Zof AI is hiring for this role in San Francisco, CA. This is a full-time opportunity for candidates who want to contribute directly to the development of ambitious AI products in a high-performance environment.
Deep, hands-on experience building production features on top of LLM APIs is required.
About this Role
Zof AI is seeking a Generative AI Engineer to build product features on top of frontier model APIs. This role owns the model-facing layer of our products: retrieval and RAG pipelines, agent planning and orchestration, multi-agent frameworks, and the context engineering that makes AI systems reliable in production. If you have worked as a GenAI Engineer, LLM Engineer, RAG Engineer, or Algorithm Engineer, this is that discipline at Zof AI. The ideal candidate has shipped LLM-powered features to real users and treats quality, cost, and latency as engineering constraints, not afterthoughts.
Responsibilities
- Design and build product features on top of frontier model APIs.
- Build and tune retrieval and RAG pipelines end to end.
- Design agent planning, tool use, and multi-agent orchestration.
- Own prompt and context engineering as a disciplined, tested practice.
- Wire evals into the development loop so quality is measured, not assumed.
- Optimize the cost, quality, and latency of AI features in production.
- Collaborate with product and engineering to ship reliably and fast.
- Own model-layer systems from design through production.
Requirements
- Experience shipping LLM-powered features to production.
- Strong software engineering foundation.
- Working knowledge of retrieval, RAG, and agent patterns.
- Fluency with the modern model API and tooling ecosystem.
- Judgment about quality, cost, and latency trade-offs.
- Clear written and verbal communication.
- Comfort operating in a fast-moving environment.
- Evidence of building high-quality technical work.
Nice to have
- Experience with multi-agent frameworks or agent orchestration systems.
- Experience building or using eval harnesses.
- Experience with TypeScript, Python, Node.js, Postgres, or similar technologies.
- Experience with fine-tuning or model adaptation.
What we provide in San Francisco
- MacBook Pro
- Premium AI development tools
- Cursor Ultra
- Claude Code Ultra
- OpenAI Codex Max or equivalent advanced AI tooling
- Access to a high-performance AI product environment
- Close collaboration with leadership, engineering, and customers
- Opportunity to work in the San Francisco AI ecosystem
- Wellness and productivity support where applicable
- Competitive startup environment
- High ownership
- Direct product impact
Benefits may depend on role and final offer terms.
