📋 Description

• Lead pre-close security due diligence on prospective acquisitions — coordinate external penetration testing, threat-model the target's 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 Anthropic's 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 Anthropic's 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 team's 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 team's security automation roadmap

🎯 Requirements

• 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 — you've 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.

🏖️ Benefits

• Competitive compensation and benefits • Optional equity donation matching • Generous vacation and parental leave • Flexible working hours • Lovely office space for collaboration
