Staff / Principal

As Claude's capabilities grow, so does our responsibility to ensure those capabilities reach the right people. The Access Programs 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.

• 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.
• Partner closely with policy, enforcement, threat intelligence, product, research, and go-to-market teams.
• Build systems that identify account compromise and takeover, apply mitigations in real time, and carry affected accounts through to full remediation.
• Design and build the dashboards, alerting, and internal admin tooling.
• Integrate with third-party identity verification and data enrichment vendors.

• A Bachelor's degree in Computer Science, Software Engineering, or comparable experience.
• Experience building and operating backend systems in production.
• Strong coding skills in at least one general-purpose programming language, and experience building software with AI coding tools.
• 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.

• 8+ years of industry software engineering experience.
• Experience building shared platforms or foundational services.
• A track record of working across functions.
• 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.
