Job summary

AssemblyAI is seeking a Senior Design Engineer to own the craft and feel of our product experience from the Playground to the dashboard. You’ll design and build interfaces for developers in React and TypeScript, shaping interaction states, motion, and information density.

You lead with design and ship end-to-end, working cross-functionally with engineering, marketing, and sales. A strong design portfolio and expert Figma skills are required, plus frontend engineering experience.

Qualifications

• A strong portfolio of shipped product work demonstrating design taste and craft.
• Genuine UX and visual design ability from concept through high-fidelity execution.
• Deep proficiency in Figma, able to move from low-fidelity exploration to high-fidelity, dev-ready designs and maintain shared component libraries.
• Solid frontend engineering skills, building production interfaces in React and TypeScript.
• Fluency with AI-assisted design and development, and building AI-native interfaces.
• Comfort operating with ambiguity and owning outcomes end to end.

Responsibilities

• 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
