Senior Research Scientist

Proving who someone is online has never been harder or more important. You'll research how to detect fraud and verify identities more accurately. Your work will include detecting AI-generated and manipulated images, understanding how models perform across populations, and finding patterns in how attackers behave.

You bring depth in at least one of computer vision, mathematics and statistics, or identity verification and fraud prevention. You test ideas with focused experiments and follow what the results show. You'll work with our ML and engineering teams to turn your findings into defenses for real customers, and you'll get to publish your work.

WHAT YOU’LL DO AT PERSONA

• Lead research on open problems in identity verification and fraud prevention, using focused experiments to test new ideas quickly.
• Develop methods to detect manipulated documents, AI-generated images and emerging fraud attacks.
• Evaluate how reliably our models perform across different populations
• Uncover the patterns in verification data that reveal fraud, and prove they're real signal and not noise.
• Calibrate model confidence and measure fraud events with limited labeled data.
• Partner with ML and engineering to turn research prototypes into production models.
• Publish at top venues such as CVPR, NeurIPS and USENIX Security, and stay active in the research community.
