Fullstack Engineer

What you'll do

Build and own features across the stack, from database and API through to the interface users touch

Design and implement the API endpoints new product surfaces depend on

Implement frontend work coming from design, from small UI corrections through to full components and flows

Ship experiments and instrumentation on activation, conversion, and engagement flows, and iterate on what the data says

Work on generative AI product surfaces: prompt flows, generation pipelines, the places where model behavior meets UX
