Staff+ Software Engineer, Safeguards Infrastructure

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.

We are looking for software engineers to help build the foundational pieces for safety, oversight and intervention mechanisms of our AI systems. As a software engineer on the Safeguards team, you will work to monitor models, prevent misuse, and ensure user well-being. This role will focus on building systems to detect unwanted model behaviors and prevent disallowed use of models.

• Develop the foundational systems which power Safeguards, including infrastructure for data storage and management, metric and evaluation systems, and tooling for human and agentic review.
• Ensure the day-to-day running of Safeguards systems and hold a high operational bar which serves both safety and customers while reducing the amount of human intervention and oversight required.
• Build robust and reliable multi-layered defenses for real-time improvement of safety mechanisms that work at scale.

• Bachelor’s degree in Computer Science, Software Engineering or comparable professional experience.
• Proficiency in Python.
• Ability to work across the stack.
• Strong communication skills and ability to explain complex technical concepts to non-technical stakeholders.
• Strong candidates may also have: 7+ years of experience, experience building trust and safety, anti-spam, fraud or abuse detection and mitigation mechanisms for AI/ML systems, experience building metrics and measurement systems or data and privacy management systems, experience working with operational teams to build custom internal tooling, proficiency in TypeScript or Rust, experience with Claude Code or similar agentic coding tools.

Annual Salary: £325,000—£395,000 GBP.
