Engineering Manager, UI Platform

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

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.

Responsibilities

• Lead and grow the UI Platform team, setting technical direction for reliability, performance, and developer experience across all Claude.ai surfaces
• Own the foundational systems that product teams depend on: shared components, BFF APIs, build and deploy pipelines, observability, and performance infrastructure
• Design and evolve the API layer that powers Claude.ai ‘s client applications, ensuring clean abstractions and reliable contracts for product teams
• Drive improvements to developer velocity—reducing friction, improving tooling, and enabling teams to ship features faster and more safely
• Establish and maintain high standards for latency, reliability, and quality across the platform
• Partner closely with product engineering, infrastructure, and leadership to align platform investments with product priorities
• Create clarity and direction in a fast-moving, ambiguous environment where priorities shift as Claude.ai evolves
• Build a culture of technical excellence, collaboration, and continuous improvement within your team

You may be a good fit if you

• Have 10+ years of software engineering experience, with significant time spent building platforms, developer tools, or infrastructure for consumer-facing products
• Have 5+ years of engineering leadership experience, including managing and growing teams in high-growth environments
• Have deep expertise in modern web development stacks (React, Next.js, TypeScript) and experience designing and evolving APIs
