Software Engineer

Who you are

• 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/TypeScript 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
• Experience working on and building operating systems, browsers, or deeply OS-integrated software (screensharing, 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 applications and a drive to make that vision a reality
• Have experience with IPC (Inter-Process Communication) and security in desktop applications
• We encourage you to apply even if you do not believe you meet every single qualification

What the job involves

• 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 (TypeScript, 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

The application process

• Deadline to apply: None. Applications will be reviewed on a rolling basis
