Job summary

Zof AI in San Francisco, CA, seeks a Content Designer to shape how our AI talks to people who depend on it. You will own tone, flow, and how the system handles uncertainty, designing language as an interface between users and technology.

Sitting between design, product, and AI engineering, you will test prompts against transcripts, iterate on conversations, and ensure trust is built sentence by sentence across surfaces.

• Design the conversational behavior of Zof AI products: tone, personality, and flow.
• Design how the AI handles uncertainty: when it hedges, asks, or escalates.
• Write and test system prompts and response guidelines with AI engineers.
• Design human-handoff moments so escalation feels safe, not broken.
• Review real transcripts and iterate on how conversations actually go.
• Partner with the evals team to make conversation quality measurable.
• Keep a consistent voice across product surfaces and channels.
• Raise the bar for how the product communicates under every condition.

Job description

Zof AI is seeking a Content Designer to shape how our AI talks to the people who depend on it: tone, flow, and above all how it handles uncertainty. When the AI is confident, unsure, or wrong, what it says next is a designed decision, and this role owns it. Sitting between design, product, and AI engineering, the ideal candidate treats language as an interface, tests their work against real transcripts, and knows that trust in an AI product is won or lost sentence by sentence.
