Senior Staff Software Engineer

About the Role

Anthropic’s Consumer Products team is hiring a Senior Staff Software Engineer to serve as the technical lead for Claude’s core chat experience on mobile — the surface where most people meet Claude for the first time. You’ll own the technical direction for our iOS and Android apps and shape how the chat interface evolves across mobile and web, working closely with product, design, and partner teams to deliver the most compelling way to talk to an AI.

This is a deeply hands-on staff+ role. You’ll write code, set architectural direction, and make the hardest technical calls — but the real measure of success is influence: building the credibility and partnerships that let a growing organization move together. You’ll help us figure out not just how to build, but what to build, as the product and the models underneath it evolve in tandem.

We care as much about craft as we do about capability. The right person obsesses over how the app feels — performance, polish, the small details that make software feel alive — and knows how to put systems in place so a fast-moving team can keep that bar high.

In this role, you will:

• 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.
• Build across the org: Partner with teams like Claude Code, Cowork, and Growth so their work lands seamlessly in the app — and so the app makes their work better.
• Go deep on the platform: Push into iOS and Android internals — rendering, text, streaming, performance — to unlock experiences that aren’t possible at the app layer alone.
• 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.

You might be a good fit if you:
