Staff+ Application Security Engineer - M&A

Anthropic's Application Security team secures the systems that build, serve, and increasingly are Claude , and as Anthropic's footprint grows, that mandate now extends to companies and codebases we bring in from outside. This role establishes that function.

You'll own security due diligence and secure integration for Anthropic's acquisitions , assessing a target's security posture pre-close, writing the security risk readout for leadership, and after close, bringing acquired systems up to Anthropic's bar. Security has been part of every deal to date, but this is the first dedicated role for it: you'll formalize the playbook, the risk model, and the tooling, and make them repeatable.
