ABOUT THE TEAM & ROLE

Our scrum team of 8 is responsible for the backend part for SentinelOne’s main productline - Endpoint Protection - securing tens of millions of devices across the globe of all kinds of OS (Windows, Linux, macOS), and processing billions security events every day.

• We are primarily building “remote update services” that ensure efficient and timely delivery of detection content across S1’s agents on the protected devices to ensure the ability of our SW to respond to the latest cyber threats and 0-day vulnerabilities in real time, and prevent the harm.
• We also enable features within our cloud-based Management console (a large-scale distributed system, with a client facing, data-heavy & complex web application, that can be seen in many S1 vs. Ransomware demos),that allow tens of thousands of users on IT security teams of our clients to manage our security SW deployed on endpoints in client’s environments, and to administer these detection content updates.

You’ll be joining a team with a significant impact on how our customers’ environments (incl. 4 or Fortune10 companies, hundreds of Global2000 or governments) are protected, how they interact with agents, gain visibility into their security posture, and understand the risks and act upon them. As core team at S1, we’re heavily involved in every end-to-end effort, features development and are key contributors to the design and build of the right architecture of S1’s cybersecurity solution to match the scale & hyper-growth of our business.
