Job Description

Own end-to-end product design for agentic chat experiences in GTM One at ZoomInfo, from behavior and trust to costs, proof-before-launch, and shipping in code.

Responsibilities

Lead the agent experience across universal chat, including how the agent communicates status, requests input, and reports progress on long-running work.
Design interaction patterns that let agents create artifacts, apps, and automations built on context, including how those outputs appear to the customer.
Build cost estimation and credit-approval moments into chat so customers understand what an agent action costs before and after it runs.
Use evals as a design instrument: apply evaluation results to confirm readiness before launch and decide what to change after real users engage.
Define trust mechanics for calibrating confidence in agent output, including how failures, uncertainty, and partial results are surfaced.
Prototype in code: open pull requests and ship working proposals alongside engineering.
Partner with product management and engineering on orchestration and tool infrastructure while owning the customer-facing experience.
Define problems alongside solutions, using thin briefs and operating as a product thinker across the scope you own.

Requirements

At least 2 years designing AI or agentic products where model behavior was the product itself (not AI features layered onto a conventional surface), with the ability to discuss what went wrong in front of real users.
Experience running evals: built or used evaluation setups for an agent, including how you determined readiness before launch and what changed after real users used it.
Proven shipping in code: prototype with AI coding tools (not only in Figma), open pull requests, and read a backend contract even if you are not an engineer by title.
Working understanding of LLM behavior in production: latency, streaming, tool calling, confidence, and failure modes, with design that addresses these realities rather than only the happy path.
Experience collaborating directly with engineering in their channels and on their timelines as a core part of shipping.

Preferred

Domain depth designing for sellers, marketers, RevOps, or CS within a CRM, sales-engagement, data, or revenue-intelligence product.
Experience navigating enterprise complexity, data-dense interfaces, bulk operations, or long-running jobs while maintaining end-user clarity.
Experience designing for products where usage directly costs the customer money.
Comfort blending UX research with agentic design, using research to predict and evals to confirm.

How We Evaluate

Assessed across four axes: context engineering and agentic systems (including eval experience); blend of UX research and agentic design; aesthetic quality and experience craft; and engineering fundamentals.
Interviews include:
- Walking through a real agent-surface decision, including an argument you lost.
- An eval you ran and what it changed.
- A live conversation about a go-to-market workflow.
- A working session on an open problem.
- A look at your own tooling.
No spec work, no unpaid take-home, and no design challenge we would not actually ship.

Location: Waltham, MA (onsite)

Salary: USD 171,430 - 269,390 per year
