Software Engineer, Desktop

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.

We're looking for desktop app engineers to join our Claude product team and help build native applications that harness the transformative power of advanced language models. Your mission will be to package our AI capabilities into elegant desktop experiences that put unprecedented capabilities at users' fingertips. You will work with a talented team of engineers, researchers, and product specialists to design and implement key components that bridge our AI technology with intuitive user interfaces.

Join us in this exciting mission to transform how people engage with our AI technology and unlock new realms of human potential.

Today, our app is mostly web-based – but we’re eager to build the best possible version of Claude for macOS and Windows with a mix of both native and web technologies. You might be a great fit for this role if you’re up for the challenge of learning multiple programming languages.

We are more interested in strong engineers excited to learn new languages and technologies to build the best possible experience than we are looking for people with hands‑on experience in Chromium, Electron, C++, or the various native macOS and Windows APIs. We believe that strong engineers can learn whatever technology is best suited to build the best possible experience – and we understand that even the best engineers will have little experience with one of the operating systems and areas we’d like to invest in.

We’re looking for curious engineers excited to figure out, with us, what AI on the desktop could do.

• Develop and maintain the core infrastructure and features within Claude.ai and in our Electron-based desktop app using a typical web stack (Type Script, React)
• Use native code (Rust, Swift, C++) to bring advanced features to the desktop app, connecting Claude to macOS and Windows
• Optimize application performance, memory usage, and startup time across platforms
• Design and build robust update mechanisms and deployment pipelines
• Create monitoring tools to track application performance and user experience
• Build a strong intuition for how advanced LLMs could be most useful on your computer, augmenting humans in their work

• Have 5+ years of experience as a software engineer, with strong emphasis on desktop application development
• Have practical experience with Electron and deep understanding of its architecture
• Possess strong JavaScript/Type Script skills and experience with modern frontend frameworks
• Take a product-focused approach and care about building solutions that are robust, scalable, and easy to use
• Have experience with native module development in C++ to extend application capabilities
• Understand macOS and/or Windows platform‑specific technologies and development patterns
• Have experience with cross‑platform application packaging, code signing, and distribution
• Thrive in a fast‑paced, collaborative environment and enjoy working closely with cross‑functional teams

We’re working with a large number of technologies - and you might be an excellent candidate even if you’ve only worked with a subset of them. An ideal candidate may have never used Electron before but does have hands‑on experience in working with Chromium’s C++. Similarly, a great candidate may have worked on Electron apps, but hasn’t used C++ or Swift before.

We understand that even the best engineers will have more experience with some platforms than others.

• Experience working on and building operating systems, browsers, or deeply OS‑integrated software (screen sharing, video‑calling, game engines, etc)
• Experience integrating and working with AI/ML models and understanding their capabilities
• Demonstrated success implementing cross‑platform development strategies
• Vision for the future of AI‑powered desktop…
