Description
We're hiring a Senior Staff Software Engineer to lead the technical direction for Claude's core chat experience on mobile. You'll own the technical strategy for our iOS and Android apps and shape how the chat interface evolves across mobile and web.
As a Senior Staff Software Engineer, you'll be responsible for leading the chat experience, building across the org, going deep on the platform, raising the bar on craft, and shaping the roadmap. You'll work closely with product, design, and partner teams to deliver the most compelling way to talk to an AI.
You'll be a deeply hands-on staff+ role, writing code, setting architectural direction, and making the hardest technical calls. The real measure of success is influence: building the credibility and partnerships that let a growing organization move together.
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.
You might be a good fit if you:
- 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.
Strong candidates may also have:
- 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
