Staff+ Software Engineer (Cybersecurity Products)

• We’re looking for a Software Engineer to join the team building Claude Security. In this role, you’ll take new security capabilities in frontier models and turn them into products that customers can rely on, working across the full stack from early prototype through production
• This role sits close to both research and go-to-market. You’ll work with researchers on the team to understand what the models can do and where they fall short, and with customers and partners to understand which problems are worth solving for them. You’ll be expected to form your own view from both and to own significant pieces of the roadmap, including deciding what not to pursue
• Build and ship user-facing and/or backend features for Claude Security
• Build the agent loops, tool integrations, and enabling infrastructure for cybersecurity products
• Collaborate tightly with product managers and go-to-market to understand user needs, shape feature scope, and make informed tradeoffs as you build
• Iterate quickly based on user feedback and internal testing, improving the experience on a continuous basis
• Collaborate with research teams to identify and develop new model capabilities for security applications
