About Us:

SentinelOne is defining the future of cybersecurity through our XDR platform that automatically prevents, detects, and responds to threats in real-time. Singularity XDR ingests data and leverages our patented AI models to deliver autonomous protection. With SentinelOne, organizations gain full transparency into everything happening across the network at machine speed – to defeat every attack, at every stage of the threat lifecycle.

We are a values-driven team where names are known, results are rewarded, and friendships are formed.

About the team

Our team is responsible for Endpoint Protection services, and covers end-to-end from agent to backend to frontend the following areas:

  • Building services that process traffic between SentinelOne's Agent (which is responsible for protection across all kinds of OS - Windows, Linux, macOS) and our cloud-based Management console, and building common modules (like a communicator layer).
  • Developing a big part of backend of this Management console itself (which is in short a large-scale distributed system, a complex "control application" used by IT security teams of S1 clients - that can be seen in many S1 vs. Ransomware demos) and the management of the "fleet" of agents deployed on endpoints in client's environments.

We’re a team with a significant impact on how our customers environments 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 & triple-digit-growth of our business.
