Responsibilities:
- Design and build shared UI components, libraries, and abstractions that product teams across Anthropic use to ship consistently and efficiently on web and mobile
- Contribute to the BFF API layer that powers Claude.ai's client applications---thinking carefully about clean contracts, performance, and reliability at the boundary between frontend and backend
- Improve developer velocity across the organization by reducing friction in our build, deploy, and testing pipelines
- Work on performance and reliability: identify and resolve latency issues, improve observability, and help establish high standards that the rest of the platform team can build on
- Partner closely with product engineering teams to understand their needs, unblock them when possible, and shape platform investments around where the most impact is
- Help maintain and evolve documentation and tooling that make the platform approachable for engineers joining or building on top of it
You may be a good fit if you:

- Have strong practical skills in modern web technologies (React, TypeScript, Next.js) and experience designing or consuming APIs that serve frontend applications
- Care about developer experience and have a track record of building things that make other engineers more productive
- Have solid instincts around reliability, observability, and performance---and enjoy operationalizing those instincts in production systems
- Thrive in fast-paced, collaborative environments and enjoy working closely with cross-functional partners
- Pick up slack, even if it goes outside your job description
Strong candidates may also have experience with:
- Building shared component libraries or design systems for multiple surfaces (web, mobile, desktop)
- BFF architectures and API patterns that balance flexibility with consistency across client platforms
- Performance optimization and latency reduction in consumer-facing applications
- CI/CD, build systems, and deployment automation
- Observability and monitoring (metrics, logging, tracing)
- Working on AI/ML products or in rapidly evolving product environments
Candidates need not have:
- 100% of the skills needed to perform the job
- Formal certifications or education credentials
