Software Security Engineering Manager, Secure Frameworks

We are seeking a Security Engineering Manager to lead our Secure Frameworks Research team, which builds high-leverage security frameworks and libraries that make model development secure and prevent entire classes of vulnerabilities through careful design. You'll collaborate closely with teams and leaders across Anthropic to own critical security foundations, including cryptographic frameworks and secure serialization and authorization systems that empower teams to work securely without becoming security experts themselves.

- Design frameworks and libraries that enable secure handling of sensitive data including model weights, customer data, and training datasets

- Own what you build completely; ensuring outstanding user experience, proactive monitoring, and responsive support

- Enable other teams to build their own security solutions by providing design pattern guidance and expanding security ownership beyond your team

- Partner with product, research, and infrastructure teams, as well as other Security teams to ensure frameworks integrate smoothly with lower-layer security controls

- Make strategic decisions about which frameworks to build based on security risk and translate into prioritized roadmaps

- Define success metrics around framework adoption and impact - the team succeeds when engineers naturally reach for Secure Frameworks' tools rather than building security solutions from scratch

- Manage and grow a team of engineers to deliver high-impact projects that balance security rigor with development velocity

- 3+ years managing security engineering teams with proven track record of team productivity

- 5+ years hands-on security and software engineering experience

- Deep expertise in securing complex architectures, threat modeling, and risk assessment with ability to evaluate security tradeoffs and make risk-based decisions

- Strong cross-functional collaboration skills, balancing security requirements with developer experience and velocity

- Clear and persuasive communicator in both writing and verbal settings

- Passionate about building diverse, high-performing teams and growing engineers in a fast-paced environment

- Low ego, high empathy, and have a track record as a talent magnet
