Introduction

Josephine Is Ready for AI Security Leadership

6-year data scientist delivering FaceID spoof detection and reliability analytics at scale.

About

I make high-stakes ML dependable, when mistakes cost trust.

I’m happiest in the messy middle between models and real life, where data is noisy, attackers adapt, and uptime matters. I’ve spent my career turning security signals, telemetry, and edge cases into systems teams can actually run. The common thread is simple, I care about protecting people, not just shipping predictions.

I build ML that holds up under pressure, when the data is adversarial and the stakes are real. On biometric spoofing defense, I helped drive a false acceptance rate below 1 in 1,000,000, the kind of bar that protects both users and brands.

I also know what happens after a model ships. I’ve run daily anomaly detection and root-cause workflows on large-scale systems, reducing downtime by 5% by treating monitoring, metrics, and failure modes as product features.

And I’m comfortable moving between research rigor and practical execution. My background spans national-lab style measurement discipline and hands-on building across telemetry, logs, and image pipelines, plus teaching and enablement that helps teams adopt what we ship.

If you know a hiring manager building security ML, reliability and observability, or AI evaluation and safety, I’d love a warm intro. A LinkedIn share also helps a lot, I’m specifically looking for teams where ML quality is measured, monitored, and trusted.

Target roles: Staff Applied Scientist, Identity, Fraud, or Trust, ML Reliability or Observability Data Scientist, AI Evaluation or AI Security Lead (LLM safety, testing, guardrails)
