Responsibilities

Deliver technical or research work for application security engineering.
Collaborate with research, engineering, security, product and business teams.
Improve reliability, testing, documentation and operational readiness.
Translate complex technical questions into measurable systems or research outcomes.

Qualifications

Hands-on application and infrastructure security experience, including cloud and containerized environments
Production-quality coding ability in at least one of Python, Go, Rust, or TypeScript, with a track record of building durable systems rather than one-off scripts
Practical threat-modeling and vulnerability-identification skills — you've found and reasoned about real bugs in real systems, even if breaking isn't your primary mode
Demonstrated ability to operate with high autonomy and ambiguity — comfortable being handed a problem and a lot of latitude rather than a spec
Clear technical communication with both engineers and leadership
7+ years in application security, security engineering, or security-focused software engineering
Already use LLMs as a core part of how you work, with opinions about where they help and where they don't
Experience securing agentic, code-execution, or LLM-integrated systems specifically
Prior ownership of a bug bounty program, vulnerability disclosure program, or vulnerability-management infrastructure at scale
Background building security automation or developer-facing security tooling
Offensive security or penetration testing experience
An increasingly autonomous vulnerability pipeline — LLM-driven code analysis finds the issue, scores it for real exploitability, and opens the fix PR, with humans as the review step rather than the author
Bug bounty operations where Claude handles first-line triage and drafting, and engineers focus on the reports that actually need judgment
AI-assisted threat modeling that generates intake questions, drafts the model, and recommends which design reviews need a human in the room
Automated dependency vulnerability remediation across Anthropic's codebase
The company-wide vulnerability dashboard and SLA enforcement layer every engineering team works against
