Anthropic

Anthropic's Application Security team is responsible for securing the systems that build, serve, and operate Claude. This role will establish and lead the security due diligence and integration function for Anthropic's acquisitions. You will assess target companies' security postures pre-close, provide security risk assessments to leadership, and ensure acquired systems meet Anthropic's security standards post-close. This is a dedicated role to formalize the M&A security playbook, risk model, and tooling, making the process repeatable and scalable. While the primary focus is M&A security, you will also be an active member of the Application Security team, participating in team rituals, on-call rotations, and contributing to core AppSec projects when deal flow is quiet. The role requires comfort with ambiguity, time-sensitive work, and the ability to quickly assess unfamiliar systems under pressure.
