Software Engineer, Safeguards Infrastructure

London, UK

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. You will apply your technical skills to uphold our principles of safety, transparency, and oversight.

• 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 experience.
• 4‑10+ years of experience in a software engineering position.
• Proficiency in Python.
• Ability to work across the stack.
• Strong communication skills and ability to explain complex technical concepts to non‑technical stakeholders.

• Have experience building trust and safety, anti‑spam, fraud or abuse detection and mitigation mechanisms and interventions for AI/ML systems.
• Have experience building metrics and measurement systems or data and privacy management systems.
• Have worked closely with operational teams to build custom internal tooling.
• Be proficient in Type Script or Rust.
• Have experience with Claude Code or similar agentic coding tools.

Final date to receive applications:

Education requirements:

We require at least a Bachelor’s degree in a related field or equivalent experience.

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.

We encourage you to apply even if you do not believe you meet every single qualification. Not all strong candidates will meet every single qualification as listed. Research shows that people who identify as being from underrepresented groups are more prone to experiencing imposter syndrome and doubting the strength of their candidacy, so we urge you not to exclude yourself prematurely and to submit an application if you’re interested in this work.

We think AI systems like the ones we’re building have enormous social and ethical implications. We think this makes representation even more important, and we strive to include a range of diverse perspectives on our team.
