About this role: The Platform Product Designer is responsible for the horizontal frameworks and shared capabilities that every Cresta product is built on top of — from AI Agent and Agentic Assist to QM/Coaching and Insights. You design platforms, not point solutions. You think horizontally and systematically. You make sure cross‑cutting concerns are solved once as a reliable, extensible platform, then reused across products and customers — rather than being rebuilt product‑by‑product. Your work makes these capabilities self‑serve and customizable for both internal squads and external customers/partners. Note this is not a Design Systems-only role. Example workstreams include but are not limited to: Frontend platform (building blocks of libraries and UI frameworks) Internationalization and languages Roles and permissions / IAM Organizational and user management Accessibility / WCAG Data and metadata management Integration experience with 3rd-party data platforms Login flows and onboarding experience Notifications and alerts Privacy and PII redaction experiences SDK and dev tools Responsibilities: You'll design frameworks instead of point solutions, and the frameworks you design should be scalable, self-servable, and customizable for both business users and developers. You'll understand how data, permissions, and services flow across products, and reflect that in clear mental models in design. You'll partner with Platform PM and Platform tech leads to help shape the strategy of the platform. You'll vibe code/vibe design in Cursor or Claude for proof-of-concept, then apply rigor and thoughtfulness to make it an enterprise-ready experience. You'll advocate for craft - raise the quality bar and help the team develop a shared eye for what great looks like. You'll drive cross-squad alignment by understanding their needs, and secure buy-in and drive adoption from stakeholders. You'll have good judgment about when to ship: perfect is the enemy of good. Qualifications We Value: Education in Design, HCI, or Interaction Design, or 5+ years of equivalent industry experience. Experience designing large-scale B2B/enterprise platforms, data-rich experiences, or dev/ops tools. 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 systems thinking and end‑to‑end flows rather than isolated screens, and simple, elegant design solutions to complex problems. Strong systems thinking and technical fluency, with 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.
