Job Description
Senior Product Designer, Design Systems
Momentus Technologies
• Own the design infrastructure that accelerates Momentus' AI-first product strategy. • Audit existing product-line-specific Figma libraries, then lead the migration to a component system that lives in code with tokens as the source of truth • Build and maintain LLM-readable system documentation, accessible to designers, engineers, and Claude • Own the context layer: structured prompt libraries, MCP server integration, and system artifacts that keep Claude producing consistent, on-brand, accessible output • Establish governance that accounts for AI-generated code, not just human-authored contributions • Track and report on system health metrics tied to business outcomes: product velocity, cycle time, and features shipped, alongside coverage and adoption • Lead the design of Momentus' AI interaction patterns as the primary design surface, covering non-deterministic outputs, trust and transparency, agentic workflow UIs, and progressive disclosure of AI behavior • Define standards for how AI features look, feel, and communicate across all product lines • Create reusable patterns for supporting surfaces: onboarding flows, reporting and analytics interfaces, and dashboards • Partner with Engineering to define token architecture, component APIs, and the front-end structure that makes the system scalable and AI-agent-consumable • Collaborate with Product Management to sequence system work against the AI-first product roadmap • Elevate design team capability through pairing, critique, and informal mentorship across all product lines • Define and uphold visual and interaction quality standards across all product lines • Champion accessibility to WCAG 2.2 AA, using AI tooling (automated audits, contrast checks, alt-text generation) to accelerate compliance rather than treat it as overhead • Contribute to design reviews with feedback grounded in system standards and AI-first principles • Own annual VPAT generation across all product lines, coordinating with Engineering and QA to assess conformance, document findings accurately, and publish updated reports on a defined cadence
Job Requirements
- Demonstrated experience building or significantly maturing a design system in a multi-product B2B SaaS environment
- AI-assisted workflows are your primary working mode today, specifically tools like Claude, Claude Code, and Claude Design.
- Comfortable producing shippable components and contributing to a shared component repo.
- Fluent in design tokens as a source-of-truth architecture, component APIs, and the front-end structures that make a system AI-agent-consumable
- Experience designing AI interaction surfaces, including non-deterministic outputs, agentic workflows, or trust and transparency patterns
- Strong communication and documentation skills, able to write system guidance that is as useful to an LLM as it is to a human engineer
- Experience working in a remote, cross-functional environment
Benefits
- Flexible work arrangements
- Professional development opportunities
