About the Role

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.

The right candidate is a strong generalist engineer with the technical depth to engage with research, the product instincts to know what's worth building, and the drive to move fast. Prior security experience is useful but not required; range across the stack and good judgment about what to build matter more.

Responsibilities

• 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

You may be a good fit if you:

• Contribute across the stack, from front-end UI to back-end infrastructure
• Are proficient in TypeScript, Python, and/or Go and have experience building distributed systems
• Enjoy fast iteration and are energized by prototyping new ideas
• Are comfortable working closely with research and go-to-market teams
• Have strong communication skills and can work effectively across functions
• Have 7+ years of experience as a software engineer

Strong candidates may also have:

• Experience building client-side terminal applications
• Experience developing cybersecurity products
• Experience in incident response, reverse engineering, network analysis, penetration testing, or similar fields
• Experience building skills, plugins, or hooks in Claude Code or similar tools
• Experience building with Claude Managed Agents or similar frameworks

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