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.
