Staff+ Application Security Engineer - M&A

<div class="content-intro"><h2><strong>About Anthropic</strong></h2> <p>Anthropic’s mission is to create reliable, interpretable, and steerable AI systems. We want AI to be safe and beneficial for our users and for society as a whole. Our team is a quickly growing group of committed researchers, engineers, policy experts, and business leaders working together to build beneficial AI systems.</p></div><h2>About the role</h2> <p>Anthropic&39;s Application Security team secures the systems that build, serve, and increasingly <em>are</em> Claude — and as Anthropic&39;s footprint grows, that mandate now extends to companies and codebases we bring in from outside. This role establishes that function.</p> <p>You&39;ll own security due diligence and secure integration for Anthropic&39;s acquisitions — assessing a target&39;s security posture pre-close, writing the security risk readout for leadership, and after close, bringing acquired systems up to Anthropic&39;s bar. Security has been part of every deal to date, but this is the first dedicated role for it: you&39;ll formalize the playbook, the risk model, and the tooling, and make them repeatable.</p> <p>This is an AppSec role first. You&39;ll be an active member of the Application Security team — same rituals, same on-run rotation, same tooling, working alongside engineers securing Anthropic&39;s own agentic product surfaces. The expectation is the same too: we use Claude as our primary tool, and you&39;re expected to automate the repeatable parts of diligence and integration as you go, so each acquisition is easier than the last. When deal flow is quiet, you&39;ll pick up core AppSec project work; when it&39;s active, M&A is your priority.</p> <p>We&39;re upfront that the center of gravity here is M&A rather than core product security. It&39;s burstier, more assessment-
