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. We have multiple teams that are currently hiring within Safeguards. Team placement occurs after the interview process, taking into account your interests and experience alongside organizational needs. This flexible approach allows us to match talented engineers where they'll have the greatest impact and growth potential. Responsibilities: * 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.
