About Cyera

Come join the company building the security operating model for the age of AI. AI has changed how data is used — and security must change with it. Cyera's mission is to empower businesses to accelerate AI Adoption by defining a holistic approach to securing AI - from data to access to model. Instead of perimeter controls and static policies, Cyera provides a unified control plane that understands relationships between data, access, and behaviors across humans, systems, and AI. Backed by the world’s leading investors and working with a large and growing list of Fortune 1000 companies, we are looking for world-class talent to join us as we usher in the new era of data and AI security.

About the Role

As a Data Scientist on Cyera’s Research team, you’ll develop and productionize ML/AI models that power our classifications and insights. You’ll partner closely with Product and Engineering to turn open-ended data-security challenges into measurable experiments and shipped features. You’ll own the end-to-end lifecycle—from problem framing and data strategy to evaluation, deployment, and ongoing monitoring—helping customers discover, protect, and govern their data at scale.

What You’ll Do

• Responsibility for an end-to-end research process. That includes identifying the problem, feature engineering, model development to deployment, outcome analysis, and refinement.
• You will be a hands-on domain leader, laying the foundations of our data science workflows and algorithms. This is an excellent opportunity to work with endless amounts of user data and creatively generate insights that will increase the ability to classify tons of data.
• Develop, evaluate, and maintain machine learning and NLP solutions to enhance Cyera’s core capabilities in sensitive data classification.
• Innovation and creative thinking are the keys! Implementing ML models to the entire research process - clustering, text extraction, document analysis, and tabular data classification.
• Close interaction and collaboration with an excellent team of engineers, data analysts, and security researchers.

Requirements

Who You Are

Must-Haves

• BSc in computer science, math, physics, or a related field
• 5+ years of experience as a data scientist
