Software Engineer, Claude.AI

We are looking for a software engineer to join our Claude.AI product team and help build innovative interfaces and APIs that enable powerful interactions with advanced language models. At Anthropic, we're not just building AI tools; we're reinventing how machines work with humans! You will work with a talented team of engineers, researchers, design and Product teams to design and implement key components of our product and platform, pushing the boundaries of what's possible with AI-powered productivity tools.

We have multiple roles open on this team and are looking for experienced engineers at different stages in their career who are excited about this space and our mission.

• Architect and build core components of the API layer that enables seamless interaction with large language models.
• Develop intelligent conversational interfaces that leverage the power of language models to streamline tasks and boost productivity.
• Optimize the API and interfaces for performance, scalability, and an intuitive user experience.
• Collaborate with researchers to continuously improve interfaces based on real-world user interactions and feedback.
• Implement tools and processes to monitor model behavior, performance, and alignment with user needs.
• Contribute to the development of novel human-machine interaction paradigms that redefine how we work with AI.

You might be a good fit if you:

• Have 2+ years of experience as a software engineer, preferably building APIs and/or interfaces.
• Have strong coding skills and experience with service-oriented architectures.
• Take a user-centric approach to product development, prioritising solutions that are robust, scalable, and intuitive.
• Are passionate about the potential of AI to revolutionise the way we work and eager to tackle cutting-edge challenges in human-machine collaboration.
• Thrive in a fast-paced, collaborative environment and enjoy pair programming (we love to pair!).

Strong candidates may also:

• Have experience with REST APIs.
• Have experience with React and frontend frameworks.
• Have experience with containerisation and DevOps.
• Have experience with QA and testing automation.
• Have experience with privacy and security best practices.
• Possess a vision for the future of human-machine interaction and a drive to make that vision a reality.

The expected salary range for this position is: Annual Salary: $300,000—$405,000 USD.

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.

US visa sponsorship: We do sponsor visas! However, we aren’t able to successfully sponsor visas for every role and every candidate; operations roles are especially difficult to support. But if we make you an offer, we will make every effort to get you into the United States, 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.
