  • Build infrastructure to measure, monitor, and mitigate safety risks such as harmful content, bias, deepfakes, intellectual property issues, and misuse at global scale.
  • Develop tools, pipelines, and evaluation frameworks that enable rapid iteration on safety policies in collaboration with researchers, product, and policy teams.
  • Architect robust feedback loops between user interactions, model outputs, and training data to continuously improve safety while maintaining high performance and low latency.
  • Own full-cycle development of safety features: from problem definition and prototyping to deployment, monitoring, incident response, and long-term refinement.
  • Partner closely with the Imagine engineering, research, and product teams to embed safety into core features and deliver delightful yet responsible user experiences.

BASIC QUALIFICATIONS:

  • Proficiency in Rust, with a strong track record of writing clean, efficient, maintainable, and scalable code.
  • Experience designing and building production safety, trust & safety, or content moderation systems for consumer-facing products at scale.
  • Hands-on expertise developing real-time detection systems, data pipelines, or evaluation frameworks for high-throughput AI applications.
  • Proven ability to deliver robust, reliable solutions that reach millions of users while maintaining high standards of uptime and performance.
  • Strong problem-solving skills and a passion for turning complex safety challenges into practical, high-impact engineering solutions.
  • Deep enthusiasm for responsible AI development and a commitment to building systems that advance humanity’s understanding while protecting users.

PREFERRED SKILLS AND EXPERIENCE:

  • Experience with multimodal content safety (images, video, audio) or generative AI safety in production environments.
  • Familiarity with machine learning classifiers, safety evaluation, red-teaming, or adversarial testing for media generation models.
  • Background in distributed systems, real-time inference serving, Kubernetes, observability tools, or large-scale data infrastructure.
