Senior Software Engineer, UX

About the role:

We're looking for a Senior Software 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.

What You’ll Do:

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

What You’ll Need:

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
