You will play a key role in supporting our Eastern Europe & CIS sales organization, helping customers discover the value of Imperva’s Application Security solutions.

Why join Thales?

At Thales, cybersecurity is about more than technology — it is about protecting what matters most.

Following our growth and the acquisition of Imperva, we are looking for an experienced, customer-focused Sales Engineer to strengthen our Eastern Europe & CIS team. This is an opportunity to work with leading application security technologies, collaborate with talented sales professionals, and make a tangible difference in how organizations protect their most critical applications and valuable data.
