About The Position

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 Claude.ai is Anthropic's flagship consumer product, spanning web, mobile, desktop, and browser extensions—and it's growing fast. We're looking for an engineering leader to own the foundational platform that powers all of these surfaces: the shared infrastructure, APIs, tooling, and systems that enable product teams to ship reliably, quickly, and with confidence. In this role, you'll lead the team responsible for reliability, latency, developer velocity, and common components across Claude.ai 's UI surfaces. This includes the backend-for-frontend (BFF) APIs that power our client applications. Your work will directly determine how fast customer, partner, and product teams can innovate—and how stable their experiences are when they ship. This is a highly technical leadership role: you'll stay close to the code, drive architectural decisions, and build the systems that let others move faster. This is a unique opportunity to shape the developer experience and platform foundations for one of the most rapidly evolving AI products in the world. You'll partner closely with product engineering teams, infrastructure, and leadership to ensure Claude.ai scales gracefully as we grow.

Requirements

Have 10+ years of software engineering experience, with significant time spent building platforms, developer tools, or infrastructure for consumer-facing products

Have deep expertise in modern web development stacks (React, Next.js, TypeScript) and experience designing APIs that serve frontend applications
Are passionate about developer experience and have a track record of building tools and systems that make other engineers more productive
Have strong opinions on reliability, observability, and performance—and know how to operationalize those opinions at scale
Can balance technical depth with strategic thinking, staying hands-on while also setting long-term direction
Thrive in ambiguity and can create structure and clarity for your team when the path forward isn't obvious
Communicate effectively across functions and can build alignment with product, design, and infrastructure partners

Nice To Haves

Building and scaling platforms for multiple surfaces (web, mobile, desktop, extensions) with shared infrastructure
