  • Collaborate closely with security, product, and infrastructure teams to bring research ideas into stable, scalable production systems

Requirements

  • 5+ years of experience in abuse prevention, trust & safety, or security engineering
  • Strong programming skills in JavaScript/TypeScript and Python
  • Hands-on experience working with LLMs, including prompt engineering, evaluation, and fine-tuning
  • Solid understanding of cloud infrastructure, including AWS
