• 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

• Take a defined design direction and execute it with precision, finalizing the details that elevate a feature from functional to delightful • Make confident trade-off decisions where design ideals, product needs, technical constraints, and timelines collide — without losing the thread of what matters most • Adapt designs in real time as customer research, usage data, and prototype feedback reshape the problem • Use AI fluently across your workflow — for research synthesis, exploration, prototyping, and compressing the path from idea to artifact • Own the end-to-end design of meaningful features and flows, from problem framing through high-fidelity execution and post-launch refinement • Partner closely with Product and Engineering across multiple squads, fluidly context-switching without losing quality or momentum • Apply and extend our design system thoughtfully, contributing patterns back as you go • Raise the quality bar through strong critique, generous collaboration, and consistent craft

Role Description We are looking for a UX Designer to support the evolution of the platform and related cross-business digital initiatives. The role focuses on creating high-quality wireframes, prototypes, and scalable design system components while collaborating closely with product, development, and business teams. - Create wireframes, user flows, prototypes, and detailed UI designs for key components on the platform - Design solutions for cross-business unit initiatives, platform enhancements, and marketing page revamps - Take ownership of final prototypes and design documentation across multiple project phases - Collaborate with Product Owners, developers, and stakeholders to align design output with business goals and project scope - Contribute to design strategy discussions and help align design approaches across multiple platforms - Design, document, and maintain reusable components and patterns within the Design System - Support design and development teams across various business units - Work closely with developers to ensure components are implemented as intended and follow accessibility standards - Contribute to design system governance, including reviews, versioning, and adoption processes - Participate in research, usability testing, and design validation activities Qualifications - Strong experience in Product Design / UI/UX Design for enterprise or large-scale digital platforms - Proven experience creating wireframes, prototypes, and high-fidelity UI designs - Experience working with Design Systems and reusable component libraries - Strong understanding of accessibility standards and responsive design principles - Experience collaborating closely with developers and cross-functional product teams - Ability to manage multiple design streams and stakeholder expectations - Experience with design governance, documentation, and component versioning - Strong communication and presentation skills - Experience with modern design tools such as Figma - English proficiency required Requirements - Experience working in enterprise or global corporate environments - Experience with usability testing and user research activities - Knowledge of frontend implementation constraints and collaboration workflows - Experience supporting multi-brand or multi-platform ecosystems

• Drive the design vision for your product area(s), connecting long-term user needs with near-term execution plans. • Collaborate closely with product and engineering leads to shape roadmaps, clarify goals, and define success metrics. • Translate abstract, ambiguous challenges into clear design problems and informed recommendations. • Own the full design lifecycle—from discovery and wireframes to detailed interaction specs and production-ready assets. • Craft innovative experiences that balance usability, technical feasibility, and domain-specific complexity (e.g., spatial, data-rich, or mission-critical environments). • Lead and contribute to complex feature and system-level design initiatives, ensuring cohesion and scalability across the platform. • Conduct and integrate research, testing, and data insights into every phase of the design process. • Partner with UX researchers, engineers, and domain experts to ground decisions in evidence and real-world behavior. • Communicate insights through storytelling, frameworks, and documentation that foster empathy and alignment. • Contribute to the evolution of Slingshot’s design system, UI patterns, and visual standards across platforms and teams. • Apply a strong understanding of hierarchy, typography, motion, and layout to create intuitive and expressive interfaces. • Maintain a high bar for craft, consistency, and accessibility. • Collaborate fluidly with engineering, product, program, growth, sales, and marketing teams to align on vision and execution. • Serve as a thought partner to product managers and technical leads; influence trade-offs and strategic choices. • Champion a user-centered approach across the company, advocating for design best practices and systemic thinking.
