Job Title: Application Security Engineer

About the Role: The Application Security team at Anthropic is at the forefront of building security into every phase of the software development lifecycle. As an Application Security Engineer, you will partner closely with software engineers and researchers to ensure that security is a core consideration from initial design through implementation. You will lead threat modeling and secure design reviews to proactively identify and mitigate risks early, and help with continuous risk assessment. You will build tools and systems to support developers shipping code securely, adhering to secure coding best practices.

Responsibilities:

Help secure AI products and internal tools that are introducing industry-novel security risks and pushing established security boundaries

Lead “shift left” security efforts to build security into the software development lifecycle

Conduct secure design reviews and threat modeling. Identify and prioritize risks, attack surfaces, and vulnerabilities

Develop tooling to scale security code reviews and respond to developer questions, including advising developers on remediating vulnerabilities and following secure coding practices

Manage Anthropic's vulnerability management program, including integrating data ingestion pipelines, coding logic to prioritize vulnerability fixes, supporting teams remediating vulnerabilities and developing automated systems at scale

Oversee Anthropic's bug bounty program. Set scope, validate submissions, perform root cause analysis, coordinate remediation with engineering teams, and award bounties. Cultivate relationships with the ethical hacker community

Collaborate closely with product engineers and researchers to instill security best practices. Advocate for secure architecture, design, and development

Develop and document security policies, standards, and playbooks. Conduct security awareness training for engineers

Requirements:

5+ years of hands-on experience in application and infrastructure security, including securing cloud-based and containerized environments

Strong proficiency in at least one programming language (e.g., Python, Rust, Go, Java)

Lead with empathy, a collaborative spirit, and a learning mindset to work cross-functionally with engineers of all levels to build security into the software development life cycle

Leverage creative and strategic thinking to reduce risk through secure design and simplicity, not just controls

Possess broad security knowledge to connect the dots across domains and identify holistic ways to decrease the overall threat surface

Are keen to distill complex security concepts into clear actions and drive consensus without direct authority

Embody a proactive mindset to thread security throughout the product lifecycle through activities like threat modeling, secure code review, and education

Have a strong grasp of offensive security to anticipate risks from an adversary's perspective, not just check compliance boxes

Bring experience with modern application stacks, infrastructure, and security tools to implement pragmatic defenses

Are practiced at collaborating cross-functionally and effectively balancing security requirements with business objectives

Advocate for security fundamentals like least privilege, defense-in-depth, and eliminating complexity that could sub-linearly scale security through smart design

Preferred Qualifications:

Hands-on technical expertise securing complex cloud environments and microservices architectures leveraging technologies like Kubernetes, Docker, and AWS / GCP

Exposure to offensive security techniques like vulnerability testing, bug bounty, pen testing, and red team exercises

Familiarity with AI/ML security risks such as prompt injection, data poisoning, model extraction, etc. and mitigations

Experience building security tools, applications, and automated tools

Solid foundational knowledge of both software and security engineering principles and are keen to continue learning

Excellent communication skills, able to distill complex security topics for broad audiences

Worked and thrived in fast-paced environments, and comfortable navigating ambiguity

Annual Compensation Range:

$300,000-$405,000 USD

Logistics:

Minimum education: Bachelor’s 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 aren't 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.
