Staff+ Fullstack Software Engineer, Safeguards Engineering

The shape of it

In the posting’s own words

We are looking for fullstack software engineers to help build safety and oversight mechanisms for 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 while enforcing our terms of service and acceptable use policies.

What it asks for · 4

• A Bachelor’s degree in Computer Science, Software Engineering or comparable experience
• Proficiency in TypeScript and modern React; comfortable in Python for backend work
• The ability to work across the stack
• Strong communication skills and ability to explain complex technical concepts to non-technical stakeholders

Also a plus

• 8+ years of experience in a software engineering position, not including internships or co-ops
• Have experience building data-dense internal tools or operator interfaces, not just marketing or consumer surfaces
• Have experience with integrity, spam, fraud, or abuse detection and mitigation
• Have experience building trust and safety detection mechanisms and intervention for AI/ML systems
• Have experience with prompt engineering, jailbreak attacks, and other adversarial inputs
• Have worked closely with operational teams to build custom internal tooling

What the job covers

• Design and build the internal review tools analysts use to investigate abuse — dashboards, case queues, and evidence viewers that make high-volume, high-stakes decisions fast and accurate.
• Build the interfaces where humans supervise agents: streaming output, interruption and approval flows, and clear provenance for every action an agent takes.
• Surface abuse patterns to our research teams through the visualizations and exploration tools that make emerging patterns legible.
• Own the frontend architecture for tools handling sensitive data at scale — performance under large datasets, correctness under real-time updates, and access controls enforced end to end.
