About Anthropic

Anthropic’s 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

As Claude's capabilities grow, so does our responsibility to ensure those capabilities reach the right people. The Identity & Access Controls team builds the systems that verify who our customers are, grant access to advanced model capabilities for approved use cases, and ensure that access is not misused.

As a software engineer on this team, you will build the identity, vetting, and access management infrastructure that underpins our trusted access programs, along with the monitoring and enforcement tooling that keeps them safe. This work sits at the center of how Anthropic deploys frontier capabilities responsibly, balancing broad access with rigorous safeguards.

Responsibilities

Build identity verification and vetting systems (KYC/KYB) that establish who our individual and business customers are
Design and implement access control systems that grant, scope, and revoke access to advanced capabilities based on approved use cases
Build infrastructure to configure safety systems and detection thresholds on a per-customer basis for trusted access programs
Develop monitoring to detect misuse of expanded access, and tooling that enables enforcement teams to act on it
Detect and remediate account takeover
Integrate with third-party identity verification and data enrichment vendors
Create monitoring dashboards, alerts, and internal admin tooling
Work closely with policy, enforcement, threat intelligence, and go-to-market teams to ensure access decisions are well-informed and consistently applied

Requirements

A Bachelor's degree in Computer Science, Software Engineering, or comparable experience
Experience building and operating backend systems in production
Proficiency in Python and SQL
Strong communication skills and ability to explain complex technical concepts to non-technical stakeholders
Care about the societal impacts of AI and want your work to make powerful systems safer

Preferred qualifications

8+ years of industry software engineering experience (not including internships and co-ops)
Experience with identity, authentication, or authorization systems at scale
Experience with KYC/KYB workflows or identity verification vendors
Experience in trust and safety, integrity, fraud, or abuse detection
Experience detecting and responding to account takeover or credential compromise
Experience partnering with operational teams to build custom internal tooling

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.

How we're 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.
