The Opportunity As a Senior Design Technologist on the Design Foundations team, you will lead AI prototyping and internal tooling initiatives that drive precision, cohesion, accessibility, and brand consistency across the design organization. You will help ensure our AI-native platform (spanning email, calendars, docs, and agents) is supported by scalable systems that maintain our high-quality standards. You will develop AI-assisted design tooling, including prototyping frameworks, customized generation tools, and micro-interaction systems. Working in close collaboration with Product, Engineering, and Design, you will guide AI integration into design workflows from early experimentation through production deployment. In partnership with design leadership, product, and research, you will translate speculative and near-term concepts into high-fidelity, interactive prototypes. You will also build the internal tooling, frameworks, and AI integrations that enable the design organization to prototype, validate, and ship with quality and design system integrity. In this role, you will: Build high-fidelity, interactive prototypes that bring speculative and near-term product ideas to life with enough realism to be used in research, stakeholder alignment, and product decision-making. Use AI tooling and write clean, front-end code (HTML/CSS/JavaScript, React) to build micro-interactions, production-ready prototypes and develop and refine internal tools to support Design workflows. Build custom AI API integrations, structured outputs, workflows and skills that integrate with our design tokens, components, accessibility standards, and motion system. Create surface templates and prompting frameworks to accelerate prototyping experimentation across the design org. Partner with the Design System and Accessibility teams to develop tools that augment the efficiency and scale of their work. Help define how AI integrates into our front-end workflows, including validation, CI checks, token enforcement, and refactoring for cohesion. Introduce on-brand motion and micro-interactions that elevate clarity and delight. Develop reusable prototyping frameworks and internal tooling that help the broader team explore and validate ideas more quickly. Help define Superhuman's approach to AI-native design: the interaction patterns, design principles, and prototyping practices that will influence how we build for years.
