Senior Design Engineer, AssemblyAI

• A strong portfolio of shipped product work that demonstrates real design taste and craft
• Genuine UX and visual design ability, from concept through high-fidelity execution
• Deep proficiency in Figma, comfortable moving from low-fidelity exploration to high-fidelity, dev-ready designs and maintaining shared component libraries
• Solid frontend engineering skills, comfortable building production interfaces in modern React and TypeScript
• Fluency with AI-assisted design and development, and a real instinct for building AI-native interfaces
• Comfort operating with ambiguity and owning outcomes end to end

Desirable

• We're looking for a Senior Design Engineer to own the craft and feel of AssemblyAI's product experience end to end
• This person will design and build the interfaces our developers live in, from the Playground to the dashboard, and hold the bar on how everything looks, moves, and feels, not just whether it works
• This person should have a strong design background paired with real frontend engineering ability, and be deeply interested in what exceptional product design looks like in an AI-native, developer-facing product
• You lead with design. Engineering is how you bring that design to life, because you don't have to hand your vision off to someone else to build it. You care about the details other people skip: interaction states, motion, hierarchy, information density, the difference between a UI that works and one that feels right
• This is a cross-functional role that requires close partnership with engineering, marketing and sales, and the judgment to move from a rough idea to a polished, shipped experience without waiting for a spec
• Own the visual and interaction design of our core product surfaces, then build them in production React and TypeScript
• Set the bar for UX quality across the product: interaction states, motion, hierarchy, and the details that separate a working interface from one that feels considered
• Take rough product ideas and turn them into polished, high-fidelity experiences, prototyping quickly to pressure-test direction before we commit
• Shape and steward our design system and visual language so quality scales as the product grows
• Partner directly with engineering and marketing on direction, not just execution
• Use AI tooling and agents as a core part of how you work, designing and shipping faster because of it
