Senior 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.

• 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.

• Have led technical direction across teams you didn’t manage, and can point to specific moments where you built credibility and brought people along.
• Are deeply expert on at least one mobile platform — iOS preferred — including the layers below the framework: rendering, performance, memory, text.
• Have great product instincts and care about craft. You notice when something feels off, and you’ve fought for the details that make consumer software feel great.
• Have shipped consumer‑scale mobile apps and put the systems in place (performance budgets, quality gates, observability) that let a team move fast without breaking things.
• Work well with product, design, and partner engineering teams — you’re the person they want in the room when a hard call has to be made.

• Experience building AI/LLM‑powered or real‑time streaming chat interfaces.
• Depth across both iOS and Android, or native + cross‑platform.
• A track record of seeing a multi‑quarter technical strategy through from proposal to outcome.
