Staff+ Software Engineer, Privacy

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

Anthropic is working on frontier AI systems that handle sensitive information at enormous scale. How we protect that data, and how we build privacy into our systems rather than bolting it on afterward, is central to our mission of building AI that is safe and beneficial.

This is a foundational role. As one of our first dedicated privacy engineers, you will help establish the privacy engineering function at Anthropic and shape how privacy is designed into our AI systems from the ground up. You'll sit within our Data Infrastructure team, architecting privacy-preserving systems, leading the implementation of privacy-enhancing technologies across our infrastructure, and providing technical leadership on privacy across engineering, research, and product teams.

You'll work at the intersection of privacy engineering, AI safety, and distributed systems, solving problems that don't yet have established answers. This is a senior individual contributor role with high autonomy and broad influence.

Key responsibilities

Design and implement privacy-preserving architectures for AI training and inference systems operating at very large scale, using techniques e.g. differential privacy, federated learning, and secure multi-party computation

Partner with researchers to implement privacy-preserving training methods that protect user data while maintaining model quality

Build foundational privacy infrastructure, including automated data discovery, classification, access controls, audit logging, and lifecycle management

Translate regulatory requirements (e.g., GDPR, CCPA, HIPAA, the EU AI Act) into technical implementations and automated compliance controls

Architect data governance systems for tracking data lineage, purpose limitation, and retention across distributed AI systems

Lead privacy reviews and threat modeling for new models and features, identifying risks and designing scalable mitigations

Partner with product and infrastructure teams to embed privacy controls into Claude's inference systems, user interfaces, and data pipelines

Develop privacy engineering toolkits and frameworks that enable other engineers to build privacy-preserving features by default

Design privacy-preserving analytics and measurement systems that surface useful insights without exposing individual user data

Evaluate emerging privacy technologies from academia and industry, and contribute to open-source tooling and AI privacy standards

Advise on and advocate for privacy practices as a core part of how we approach AI safety

Minimum qualifications

Experience applying privacy engineering principles in production systems, including privacy by design, data minimization, and purpose limitation

Proficiency in Python, Go, or similar languages, with experience building and operating production systems at scale

Experience designing and implementing privacy infrastructure for systems with a large user base

Experience with data governance, classification, or data lifecycle management systems

Experience with distributed systems and cloud infrastructure at scale

Understanding of privacy regulations such as GDPR and CCPA, and the ability to translate legal requirements into technical designs
