About this role

Role Overview

The Staff+ Application Security Engineer - M&A role at Anthropic is a specialized position focused on establishing and scaling security due diligence and secure integration for company acquisitions. Based remotely or out of San Francisco, Seattle, or New York City, this opportunity suits an experienced security professional who thrives on assessing unfamiliar codebases and managing confidential, time-sensitive M&A risk.

Key Responsibilities

Lead pre-close security due diligence on prospective acquisitions by coordinating external penetration testing, threat-modeling target architectures, assessing controls, and delivering risk readouts.
Drive post-close security integration by setting up static and dynamic analysis coverage, tracking critical remediation to closure, and folding assets into bug bounty scopes.
Coordinate adjacent security engineering teams, including cloud, supply chain, detection, and corporate security.
Collaborate with internal stakeholders and external target company counterparts to keep security workstreams legible and transparent.
Formalize and scale the M&A security playbook, risk-scoring models, and integration checklists using Claude-powered tooling.
Participate in the team's operational on-run rotation and contribute to core application security projects between deals.

Requirements

Hands-on application and infrastructure security experience within cloud and containerized environments.
Demonstrated ability to rapidly assess unfamiliar codebases or architectures and produce prioritized risk assessments for non-security audiences.
Production-quality coding ability in Python, Go, Rust, or TypeScript.
Practical threat-modeling and vulnerability-identification skills.
Comfort operating with high autonomy, ambiguity, and tightly-held confidential context.
Clear written and verbal communication across executives, legal teams, and acquired engineering counterparts.
A relevant Bachelor's degree or equivalent combination of education, training, and experience.

Nice to Have

7+ years of experience in application security, security consulting, or security architecture.
Prior M&A security due diligence, third-party assessment, or technical due diligence experience.
Experience scaling SAST/DAST, bug bounty, or vulnerability management coverage across multiple codebases.
Track record of building security automation or tooling.
Familiarity with using LLMs in security workflows and securing agentic, code-execution, or LLM-integrated systems.
