Staff+ Application Security Engineer M&A

About Anthropic

Anthropics 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.

About the role

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

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

This is an AppSec role first. Youll be an active member of the Application Security team same rituals same on-run rotation same tooling working alongside engineers securing Anthropics own agentic product surfaces. The expectation is the same too: we use Claude as our primary tool and youre 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 youll pick up core AppSec project work; when its active M&A is your priority.

Were upfront that the center of gravity here is M&A rather than core product security. Its burstier more assessment-heavy and operates on confidential time-sensitive work. If you like parachuting into an unfamiliar codebase under time pressure and turning it into a clear risk picture for leadership this is that job.

Key responsibilities

• Lead pre-close security due diligence on prospective acquisitions coordinate external penetration testing threat-model the targets architecture assess security controls and deliver the security risk readout for leadership ahead of close and integration planning
• Drive post-close security integration stand up static and dynamic analysis coverage on acquired codebases track high- and critical-severity remediation to closure fold acquired assets into bug bounty scope and onboard repositories to Anthropics automated vulnerability remediation and reporting systems
• Coordinate adjacent security engineering teams (supply chain cloud corporate security detection & response) on their portions of each integration
• Work across a wide set of stakeholders on every deal corporate development legal security leadership and the engineering teams inheriting acquired systems internally; engineering and security counterparts at the target company externally translating between them and keeping the security workstream legible to all of them
• Formalize and scale Anthropics M&A security playbook risk-scoring model diligence runbook integration checklist and turn as much of it as possible into Claude-powered tooling rather than manual process
• Share the teams operational on-run rotation (bug bounty escalations launch consults incident response) swapping out during periods of active deal work
• Contribute to core AppSec projects between deals secure design reviews threat modeling for agentic systems and the teams security automation roadmap

Minimum qualifications

• Hands-on application and infrastructure security experience including cloud and containerized environments
• Demonstrated ability to rapidly assess an unfamiliar codebase or architecture and produce a clear prioritized risk assessment for a non-security audience
• Production-quality coding ability in at least one of Python Go Rust or TypeScript
• Practical threat-modeling and vulnerability-identification skills youve found and reasoned about real bugs in real systems
• Comfort operating with high autonomy ambiguity and tightly-held confidential context
• Clear written and verbal communication across varied audiences executives legal and corporate development partners and engineering counterparts at an acquired company

Preferred qualifications

• 7 years in application security security consulting or security architecture
• Prior M&A security due diligence third-party security assessment or technical due diligence experience
• Experience standing up or scaling SAST/DAST bug bounty or vulnerability management coverage across multiple codebases
• Track record of building security automation or tooling rather than relying solely on manual review
• Familiarity with using LLMs as a core part of your security workflow
• Experience securing agentic code-execution or LLM-integrated systems

Representative projects

• Point Anthropics internal LLM-driven code analysis and AI-assisted scanning at an acquired repository nobody here has seen and turn the output into a prioritized remediation plan in days rather than weeks
• Design the risk-scoring framework Anthropic uses to compare security posture across acquisitions of different shapes and sizes
• Build the automation that onboards an acquired codebase to Anthropics vulnerability dashboard dependency auto-patching and bounty scope without a human running a checklist
• Write the security risk memo for a live deal and present it to corporate development and security leadership

Logistics

Minimum education: Bachelors degree or an equivalent combination of education training and/or experience

Required field of study:A field relevant to the role as demonstrated through coursework training or professional experience

Minimum years of experience: Years of experience required will correlate with the internal job level requirements for the position

Location-based hybrid policy: Currently we expect all staff to be in one of our offices at least 25% of the time. However some roles may require more time in our offices.

Visa sponsorship:We do sponsor visas! However we arent able to successfully sponsor visas for every role and every candidate. But if we make you an offer we will make every reasonable effort to get you a visa and we retain an immigration lawyer to help with this.

We encourage you to apply even if you do not believe you meet every single qualification. Not all strong candidates will meet every single qualification as listed. Research shows that people who identify as being from underrepresented groups are more prone to experiencing imposter syndrome and doubting the strength of their candidacy so we urge you not to exclude yourself prematurely and to submit an application if youre interested in this work. We think AI systems like the ones were building have enormous social and ethical implications. We think this makes representation even more important and we strive to include a range of diverse perspectives on our team.

Your safety matters to us. To protect yourself from potential scams remember that Anthropic recruiters only contact you some cases we may partner with vetted recruiting agencies who will identify themselves as working on behalf of Anthropic. Be cautious of emails from other domains. Legitimate Anthropic recruiters will never ask for money fees or banking information before your first day.

How were different

We believe that the highest-impact AI research will be big science. At Anthropic we work as a single cohesive team on just a few large-scale research efforts. And we value impact advancing our long-term goals of steerable trustworthy AI rather than work on smaller and more specific puzzles. We view AI research as an empirical science which has as much in common with physics and biology as with traditional efforts in computer science. Were an extremely collaborative group and we host frequent research discussions to ensure that we are pursuing the highest-impact work at any given time. As such we greatly value communication skills.

The easiest way to understand our research directions is to read our recent research. This research continues many of the directions our team worked on prior to Anthropic including: GPT-3 Circuit-Based Interpretability Multimodal Neurons Scaling Laws AI & Compute Concrete Problems in AI Safety and Learning from Human Preferences.
