Stellar Cyber is a fast-growing Cybersecurity company focused on delivering holistic cyberattack protection to organizations while significantly reducing total costs of ownership with its innovative Open XDR (eXtended Detection and Response) platformbased on advanced ML and security technologies. Stellar Cyber has been recognized by Gartner as one of the leading XDR players.

To accelerate our growth, we are seeking a talented Security Engineer specializing in detection to join our cybersecurity team with startup passion, a can-do attitude, and a desire to make an impact, while building a future for themselves and Stellar Cyber. If you are excited to be part of a very fast-growing team with lots of opportunities, Stellar Cyber is a great place to grow your career.

Responsibilities:

  • Research and author detection rules in Sigma format. Your top responsibility will be to create out-of-the-box detection rules in Stellar Cyber’s Open XDR platform. These rules will be covering various areas in need, such as endpoints (e.g., Windows, Linux), cloud (e.g., AWS, Azure), SaaS (e.g., Microsoft 365, Google Workspace), and network (e.g., DNS metadata).
  • Manage and build detection use cases for out-of-the-box detection rules. You will be responsible for organizing detection rules into carefully designed use cases (e.g., with alert types, TTP mappings, informative alert descriptions, etc.) that help Stellar Cyber’s customers to understand and work on the rule-triggered alerts effectively.
