Staff Software Engineer, Web Platform

Anthropics 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.

is Anthropics flagship consumer product spanning web mobile desktop and browser extensionsand its growing fast. The Web Platform team owns the foundational layer that makes all of this possible: the shared infrastructure components APIs and tooling that let every other product team at Anthropic ship quickly reliably and with confidence.

As a Software Engineer on this team youll be hands-on building the platform that other engineers depend on every day. This means designing and shipping shared components and design-system-level abstractions evolving the backend-for-frontend (BFF) APIs that power our client applications and improving the build deploy and observability systems that keep running smoothly across surfaces. Your work will directly shape how fast teams across Anthropic can innovateand how stable their experiences are when they do.

This is a great fit if you care deeply about developer experience and want your engineering work to have outsized leverage: instead of shipping one feature youre building the tools and systems that make dozens of features possible.

• 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
• Design and build shared UI components libraries and abstractions that product teams across Anthropic use to ship consistently and efficiently on web and mobile
• 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

• Have strong practical skills in modern web technologies (React TypeScript or comparable frameworks) 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 performanceand 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

• Have 5 years of software engineering experience with significant time spent building shared platforms developer tools or infrastructure that other engineers rely on
• Building shared component libraries design systems or reusable UI infrastructure
• API design and and client-server architecture patterns that balance flexibility with consistency across client platforms
• Performance optimization and latency reduction in production web applications
• CI/CD build systems and/or deployment automation
• Observability and monitoring (e.g. metrics logging tracing)

Be cautious of emails from other domains. Legitimate Anthropic recruiters will never ask for money fees or banking information before your first day. If youre ever unsure about a communication dont click any linksvisit for confirmed position openings.

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. Were 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.

Anthropic is a public benefit corporation headquartered in San Francisco. We offer competitive compensation and benefits optional equity donation matching generous vacation and parental leave flexible working hours and a lovely office space in which to collaborate with colleagues.
