Software Engineer, Web Product

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.

We're looking for experienced software engineers to join our Web Product team, which owns the core Claude.ai experience—the primary way millions of people interact with Claude every day. This is where the future of human-AI collaboration takes shape.

Our team is responsible for transforming Claude from a chat interface into a true virtual collaborator: an AI that remembers context, takes action on your behalf, and works alongside you across your digital life. We're building the foundation for how people will work with AI for years to come.

You'll work across the full stack to design and ship features that make Claude more capable, intuitive, and trustworthy. This means building new interaction paradigms, integrating Claude with external tools and services, and creating experiences that feel less like using software and more like working with a thoughtful partner.

• Build and ship core features of claude.ai that define how millions of users interact with AI daily
• Design and implement new interaction models that expand what's possible in human-AI collaboration
• Work across the stack—from React frontends to Python or Go services—to deliver complete, polished experiences
• Collaborate closely with product, design, and research teams to translate cutting-edge model capabilities into intuitive user experiences
• Iterate rapidly based on user feedback and data to evolve features from early prototypes to scaled production systems
• Develop APIs and platform capabilities that enable Claude to connect with users' tools and workflows
• Contribute to the technical and product vision for how Claude evolves as a collaborative AI assistant

• Have 5+ years of experience as a full-stack software engineer, with strong skills in both frontend and backend development
• Have a track record of building 0-to-1 products—taking ideas from concept through launch and iteration to find market fit
• Excel at cross-functional collaboration with product, design, and research partners
• Are comfortable with ambiguity and can make good decisions without perfect information
• Communicate clearly and can translate complex technical concepts for non-technical stakeholders
• Care about craft—you sweat the details that make products feel great to use

• Experience building AI-powered products or working with large language models
• Background in building collaborative tools or productivity software
• Design sensibility and experience partnering closely with designers on interaction patterns
• Experience with service-oriented architectures and API design
• Familiarity with modern web development stacks (React, TypeScript, Python, Node.js)

Education requirements: We require at least a Bachelor's degree in a related field or equivalent experience.
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.

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.

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.
