About Anthropic

Anthropic’s mission is to create reliable, interpretable, and steerable AI systems. We want AI to be safe and beneficial for our users and for society as a whole. Our team is a quickly growing group of committed researchers, engineers, policy experts, and business leaders working together to build beneficial AI systems.

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:

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

Location-based hybrid policy: Currently, we expect all staff to be in one of our offices at least 25% of the time. However, some roles may require more time in our offices.

Visa sponsorship: We do sponsor visas! However, we aren't able to successfully sponsor visas for every role and every candidate. But if we make you an offer, we will make every reasonable effort to get you a visa, and we retain an immigration lawyer to help with this.

We encourage you to apply even if you do not believe you meet every single qualification. Not all strong candidates will meet every single qualification as listed. Research shows that people who identify as being from underrepresented groups are more prone to experiencing imposter syndrome and doubting the strength of their candidacy, so we urge you not to exclude yourself prematurely and to submit an application if you're interested in this work. We think AI systems like the ones we're building have enormous social and ethical implications. We think this makes representation even more important, and we strive to include a range of diverse perspectives on our team.

Your safety matters to us. To protect yourself from potential scams, remember that Anthropic recruiters only contact you from @anthropic.com email addresses. In some cases, we may partner with vetted recruiting agencies who will identify themselves as working on behalf of Anthropic. Be cautious of emails from other domains. Legitimate Anthropic recruiters will never ask for money, fees, or banking information before your first day.

How we're different

We believe that the highest-impact AI research will be big science. At Anthropic we work as a single cohesive team on just a few large-scale research efforts. And we value impact — advancing our long-term goals of steerable, trustworthy AI — rather than work on smaller and more specific puzzles. We view AI research as an empirical science, which has as much in common with physics and biology as with traditional efforts in computer science. We're an extremely collaborative group, and we host frequent research discussions to ensure that we are pursuing the highest-impact work at any given time. As such, we greatly value communication skills.

The easiest way to understand our research directions is to read our recent research. This research continues many of the directions our team worked on prior to Anthropic, including: GPT-3, Circuit-Based Interpretability, Multimodal Neurons, Scaling Laws, AI & Compute, Concrete Problems in AI Safety, and Learning from Human Preferences.
