About the role
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.
What they're looking for
- 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
More about this role
AssemblyAI builds the best-in-class Voice AI models powering the next generation of voice applications. Our models serve 600M+ inference calls monthly, process 1M+ hours of audio daily, and power 2 billion+ end-user experiences. The Voice AI space is at an inflection point; we’re looking for folks truly excited to join a small team and help define the future of the industry.
We are one of the most capital-efficient AI companies on the planet - with under 100 people generating roughly $600K ARR per employee, we sit among the top 5 most revenue-dense teams within the fastest-growing AI companies today. That's not an accident; it's a deliberate choice to stay lean, move fast, and give every person on the team outsized ownership and impact. With thousands of customers including Granola, Fireflies, Figure AI, and CallRail, the company has real scale - processing over 2 million hours of audio daily and handling more than 1 million API calls every day. This is a rare growth-stage opportunity where the business is proven and the trajectory is steep, but the team is still small enough that your fingerprints are on everything.
