About the role
Cosmon is hiring the founding product designer for Nexus to define the UX of an agentic platform that helps mechanical engineers delegate CAD, CAE, and PLM workflows. You’ll own end-to-end product design across the agent, desktop app shell, and IT/admin surfaces to build trust, observability, and recovery patterns that enable enterprise adoption. What you'll do • Own UX end-to-end for Nexus, setting the design bar across agent, desktop, and admin surfaces. • Define agent interaction patterns including plan review, step-level approvals, scope boundaries, and agent-to-human handoffs. • Design observability and verification surfaces (diffs, plans, reasoning traces, audit history) so engineers can trust and validate agent actions. • Map user stories across engineering workflows (DFM review, drawing generation, mold-flow setup, PLM check-in) and design for their stakeholders and failure modes. • Own the Nexus desktop app shell, including information architecture, navigation, and panel/command surfaces. • Design integration experiences for CAD/CAE/PLM tools that respect established mental models without inheriting legacy UI debt. • Design IT-facing experiences like installers, activation, admin consoles, deployment status, and enterprise error surfaces. • Run and partner on research with PM and engineering, including customer calls and usability sessions with F100 users. • Build a design system from scratch (tokens, components, motion, density, accessibility) and define what “shipped” means visually and interactively. What Cosmon is looking for • 7+ years designing digital products with at least 2 years owning a major surface end-to-end and shipping products to real users. • Deep CAD experience (practitioner or designer for CAD users) with fluency in tools and workflows used by mechanical engineers. • Experience designing AI-powered products or interactions on top of LLMs/generative/ML systems. • Strong systems thinking: design for state, edge cases, error paths, and recovery across multi-step flows. • High interaction and visual craft with the ability to defend pixel-level decisions and system-level architecture. • Comfortable collaborating with engineers, reading code, and participating in technical discussions. • Bias toward shipping and iterating quickly rather than perfecting abstractions. • Direct experience with agentic interaction patterns (plan/approve, observability, rollback) is a meaningful accelerant. • CAE, PLM, or PDM familiarity (Ansys, Abaqus, Simulia, COMSOL, Windchill, Teamcenter, Enovia, Aras) is a plus. • Experience designing desktop/native applications and IT/admin surfaces, and building a design system from zero.
