Full-Time Product Designer

Knapsack is building the Intelligent Product Engine—a platform that helps teams orchestrate design, code, and content into faster, more consistent digital delivery. Our mission is to move beyond static files and manual workflows, enabling structured, system-aware, AI-augmented product creation.

We're looking for a Product Designer who designs in both Figma and the browser. You've made real UX decisions, shaped usable interfaces, and shipped product. You don't just hand off designs—you bring them to life.

This role lives at the intersection of product design and front-end development. You'll design flows, components, and product surfaces—and help implement them in production. You'll collaborate closely with engineers, sometimes writing the code yourself, other times pairing or reviewing implementation.

You thrive in a componentized world, think in systems, and understand how HTML, CSS, and modern frameworks shape design decisions. You bring a structured mindset to complex problems, and you care deeply about how things look and feel.

• Design and build product UI — from early exploration to final implementation
• Work fluidly between Figma and the codebase (HTML/CSS, React, Typescript)
• Translate your own designs into responsive, accessible components
• Identify UX gaps and inconsistencies, and improve them proactively
• Lead UX work on system tools, configuration interfaces, and structured workflows
• Collaborate with engineering and product to shape features and UI patterns
• Contribute to and evolve our internal design system
• Prototype in code when it's the clearest way to show intent

• 3+ years of product design experience, with work that shows UX thinking and visual craft
• Real experience designing complex digital products—ideally B2B, system-oriented, or technical tools
• Comfortable contributing front-end code (React, TypeScript, HTML/CSS)
• A strong grasp of UX principles: information architecture, usability, accessibility
• Familiarity with design systems, token libraries, and developer-focused tooling
• A portfolio that reflects your product thinking, interaction design, and hands-on implementation
• Ability to work without detailed specs — you know how to explore, refine, and build

• Experience contributing to design systems (tokens, documentation, components)
• Understanding of accessibility standards (WCAG, ARIA)
• Background in developer tools, creative coding, or motion design
• Interest in AI-assisted tooling or systems design
