About The Role

We're looking for an AI Frontend Developer to join our Artificial Intelligence team and build the interfaces through which Yuno 's merchants and internal teams interact with AI.

You will work closely with AI engineers, backend and data teams, owning the frontend end to end: design system and reusable components, integration of LLM APIs with streaming responses, and the quality, performance and accessibility of everything we ship. We build with AI every day, and we expect you to use AI tools as a default part of how you code, test and iterate.
If you enjoy shipping polished products at a fast pace, care about the details that make an interface feel great, and want to build at the intersection of payments and AI, this role is for you.
Your contribution will be Build and evolve user-facing AI products: copilot and agent style interfaces, conversational flows, streaming responses and human in the loop review screens.
Design and maintain our design system and web components, used across Yuno 's applications and by third parties.
Build and evolve internal back-office tools used across teams to drive operational efficiency.

Write reusable, testable and efficient code, with unit and end to end tests and CI/CD as part of the workflow.

Champion an AI-first engineering culture, using AI-assisted development, code generation and automated testing as a default in your daily work.
Care for performance, accessibility and security in everything you ship.
