[Remote] Staff AI Engineer (Audio)

Note: The job is a remote job and is open to candidates in USA. Reality Defender is an award-winning cybersecurity company focused on detecting deepfakes and AI-generated media. They are seeking a Staff AI Engineer (Audio) to develop and deploy cutting-edge audio deepfake detection models, collaborating with multiple teams to ensure model robustness and performance in real-world scenarios.

Responsibilities

• Design, build, and optimize ML/DL models for production-scale audio deepfake detection, ensuring robustness across diverse real-world conditions including compression artifacts, noise, telephony, and streaming pipelines
• Partner with clients to develop a deep understanding of their production environments and define model performance criteria
• Investigate failure cases in client environments, build custom evaluation frameworks, and implement mitigation strategies spanning both Engineering and AI
• Design and execute structured experimentation roadmaps aligned with client requirements and proactive system resilience goals. Translate findings into clear and actionable insights
• Monitor, measure, and report on model performance in production using data analytics and AI observability tools (e.g. Datadog, Metabase). Identify degradation trends, data drift, and emerging threat patterns before they impact client outcomes
• Build and maintain dashboards and analytics pipelines that surface model health metrics, enabling data-driven decisions across AI, Engineering, and Product teams
• Collaborate with cross-functional partners — Applied Scientists, Deployment Engineers, and Product teams — to deploy scalable, production-grade models with clear performance benchmarks and monitoring in place

Skills

• PhD in Computer Science, Machine Learning, Signal Processing, or related field (or equivalent industry experience)
• 2+ years of industry experience building and deploying ML/DL models for AI products
