They are seeking a Senior Staff Software Engineer to lead the technical direction for Claude’s core chat experience on mobile, collaborating closely with various teams to enhance the user interface and experience.

Responsibilities:

• Lead the chat experience: Own the technical strategy for Claude’s core chat surface on mobile, and influence how it evolves across web and other clients

• Raise the bar on craft: Work side-by-side with design to ship an interface that feels fast, polished, and considered, and build the quality systems that keep it that way
• Shape the roadmap: Bring an engineering point of view to product strategy — what we should build, in what order, and why
