Job Level
About the role
- Design, build, and optimize ML/DL models for production-scale audio deepfake detection.
- Interface with clients to build a deep understanding of the production environment and scope out model performance criteria.
- Investigate failure cases in the client environment, build custom evaluation frameworks, and implement mitigation strategies that span across Engineering and AI.
- Drive model tuning and iteration for performance under a variety of real-world environments, e.g. compression artifacts, noise, telephony, and streaming pipelines.
- Design and execute structured experimentation roadmaps, centered around client requirements, anticipated future attack vectors, and proactive system resilience.
- Collaborate with cross-functional partners (Applied Scientists, Deployment Engineers, Product teams) to deploy robust and scalable models.
- Present technical findings and model performance insights to clients as well as internal stakeholders.
Requirements
