Build, maintain, and fine-tune internal tools, datasets, and evaluation pipelines for trust and safety workflows. Collaborate closely with security, product, and infrastructure teams to bring research ideas into stable, scalable production systems. About You: 5+ years of experience in abuse prevention, trust & safety, or security engineering. Strong programming skills in JavaScript/TypeScript and Python.
