About Us
At SentinelOne, we’re redefining cybersecurity by pushing the limits of what’s possible—leveraging AI-powered, data-driven innovation to stay ahead of tomorrow’s threats.
From building industry-leading products to cultivating an exceptional company culture, our core values guide everything we do. We’re looking for passionate individuals who thrive in collaborative environments and are eager to drive impact. If you’re excited about solving complex challenges in bold, innovative ways, we’d love to connect with you.
About Our Team
Our scrum team 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 building services (e.g. gateways, caching, threat data ingestion etc) that process traffic & serve for two-way interaction between S1’s agents on the protected devices and 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).
- We also enable features in this console 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 (e.g. investigating threats & notifications from protected devices; creating blocklists, exclusions, policies etc.).
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.
