As part of SentinelOne’s main product line - Endpoint Protection, we secure tens of millions of devices across the globe of all kinds of OS (Windows, Linux, macOS), and process billions of security events every day. Our team provides crucial SaaS platform capabilities, such as:
- Building services (e.g. alert pipelines, gateways, detection data ingestion, caching layers) that remotely support and enhance the agent detection mechanisms, while also providing foundational infrastructure used by internal detection/malware research and MDR teams (providing security operations services for our clients) to develop and deliver advanced detection capabilities at scale.
- Developing advanced alert reporting and visibility features that give customers timely, actionable insights into detection activity, alert life cycles and threat patterns, helping them quickly understand, prioritize and respond to events surfaced by the agents.
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 a 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.
