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. Trust, accountability, relentlessness, ingenuity, and OneSentinel define the pillars of our collaborative and unified global culture. We're looking for people that will drive team success and collaboration across SentinelOne. If you’re enthusiastic about innovative approaches to problem-solving, we would love to speak with you about joining our team!

About the team & role

Our scrum team of 6 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 hundreds of 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.
