Data Scientist

At Thales, we know technology has the ability to make our world more secure, sustainable, and inclusive – and that it’s all driven by human intelligence.

Because it takes human intelligence to build and power the systems and solutions that people depend on every day. So we stay curious and make space for diverse points of view. We share what we know and we challenge what’s possible.

We’re driving progress in some of the world’s most important industries - from the bottom of the oceans to the depths of space and cyberspace - and from manufacturing to engineering, we work together to build a future we can all trust.

Imperva, a Thales company, is a globally recognized cybersecurity leader, dedicated to securing data and applications across diverse environments. Our cutting-edge solutions empower organizations to safeguard their most critical assets, ensuring robust protection against emerging threats.

Thales believes that technology becomes truly powerful when driven by human intelligence. We value curiosity, diverse perspectives, and bold thinking—and we are proud to be ranked among Israel’s Top 50 High‑Tech Companies to Work For in 2025 (Dun & Bradstreet) and offer a flexible hybrid work model from our Tel Aviv office.
