Data Scientist (AI Security)

Thales - Imperva is seeking a Data Scientist to join our AI Protection initiative in India. Our team focuses on securing the next generation of AI powered applications and generative AI platforms. We are building and advancing our AI Firewall (AIFW) to help organizations detect and mitigate emerging threats targeting Large Language Model (LLM) systems and AI agents.

This role focuses on data centric AI: designing high quality datasets and evaluation frameworks that directly improve detection performance. You will work closely with Security Researchers who discover current attack techniques and with Data Scientists and ML engineers who develop detection models. Your work will transform emerging AI threats into structured datasets and evaluation benchmarks that strengthen our ability to detect attacks such as prompt injection, jailbreaks, model manipulation, and sensitive data exfiltration.

What will you do
- Build and maintain datasets used to train and evaluate AI security detection models.




- Collaborate with Security Researchers to convert newly discovered attack techniques, jailbreak strategies, and adversarial prompts into structured datasets and labeling guidelines.
- Design scalable workflows for collecting, generating, curating, and maintaining high quality datasets.
- Implement dataset quality processes such as filtering, deduplication, sampling, and continuous updates as the threat landscape evolves.
- Define evaluation datasets and benchmarks to measure detection performance and track model improvements over time.
- Generate synthetic and adversarial prompts to expand coverage of emerging attack techniques.
- Work closely with engineers and data scientists to integrate datasets and evaluation workflows into model experimentation, training, and production pipelines.
- Analyze detection performance and recommend improvements to datasets, labeling strategies, and model training approaches.
