Job summary

AssemblyAI is seeking a Senior Design Engineer to own the craft and feel of its 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.

Qualifications

• Strong portfolio of shipped product work demonstrating real design taste and craft.
• Genuine UX and visual design ability from concept through high-fidelity execution.

• Comfort operating with ambiguity and owning outcomes end to end.

Responsibilities

• Own the visual and interaction design of 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.
• Turn rough product ideas into polished, high-fidelity experiences, prototyping quickly to test direction before committing.
• 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.
