Detect deepfakes in audio, video, and images. Identify AI callers and add detection to live calls, meetings, and applications. Backed by Y Combinator and AI Grant.
About the role
Reality Defender's AI Red Team exists to break our own detection models before adversaries do. As a Red Team Researcher, you'll get your hands on the newest deepfake tools the moment they appear — voice clones, real-time face swaps, injection attacks, multimodal impersonations — use them the way real attackers would, and turn every failure you uncover into a measurable fix shipped alongside our AI and Data teams. Found on 1752vc Careers, the job board for startup and VC roles.
What they're looking for
- 4+ years of experience in offensive security, adversarial ML, AI red teaming, or ML engineering with a strong adversarial focus
- Hands-on experience generating synthetic media — voice cloning and TTS, face swap, lip-sync, diffusion-based image and video tools — in an offensive or research context, not just reading about it
- Strong Python skills and practical ML fluency (PyTorch or similar): you can build attack tooling, automate testing pipelines, and reason about why a model fails, not just that it did
- Working knowledge of adversarial ML techniques — evasion, adversarial perturbations, compression and post-processing attacks, data poisoning — and how to measure model robustness
- Clear communicator who can turn technical findings into prioritized, actionable guidance for engineers and non-technical audiences alike, and who thrives with ambiguity and minimal supervision
- Background in media forensics, signal processing, speech/audio, or computer vision. (nice to have)
