About the role: At Cresta, AI Builders are how we put the power of AI directly into our customers’ hands. Through these builders, our users can design, configure, test, and deploy AI agents that automate tasks, or AI workflows that augment human agents and make them feel superhuman. As a Product Designer on AI Builders, you’ll design the tools that make this possible. That means owning the end-to-end experience of how customers build, evaluate, and ship AI — navigating the nuanced interplay between agentic and deterministic workflows, and finding the right balance between the two. You’ll sit at the intersection of LLM capabilities, CX operations, and workflow design, translating powerful AI primitives into builder experiences that real contact center teams (from developers to business operators) can adopt and scale with confidence. Responsibilities: • You’ll turn the complexity of AI and business logic into builder experiences that feel intuitive and self-serve, for both technical users (developers) and non-technical ones (business operators) • You’ll pair vibe coding/design with your engineer and designer partners to spin off builder concepts and iterate them into polished, production-ready experiences • You’ll partner with PMs and tech leads to define problem spaces, north‑star experiences, and iterative milestones • You’ll run discovery and evaluative research with our users – interviews, workflow walkthroughs, usability tests, and competitive analysis, to understand how they work today and where AI can meaningfully help. • You’ll collaborate closely with PMs, MLEs, FDE/FDPMs, Customer Success, and Marketing teams across the organization. • You’ll advocate for craft – raise the quality bar and help the team develop a shared eye for what great looks like • You’ll have good judgment of when to ship: perfect is the enemy of good Qualifications We Value: • Education in Design, HCI, Interaction, or 5+ years equivalent industry experience • Experience in designing AI-driven workflows, no-code/low-code/agentic builders, or complex B2B enterprise applications • AI-native working style: comfortable using Claude Code, Cursor, MCP, or similar tools to move faster, prototype deeper, and push beyond what traditional design tooling (Figma) allows • Portfolio showcasing simple and elegant design solutions to complex problems, with a focus on end‑to‑end flows rather than isolated screens • Strong product thinking + a blend of UX disciplines (interaction design, prototyping, visual design, and user research) • Curious, adaptable, and a quick learner who thrives in a collaborative, team-oriented environment.
