Reports to: Chief Scientist

Stellar Cyber is a groundbreaking cyber security company focused on helping organizations secure their environments easily and impactfully while dramatically reducing costs with its innovative Open XDR platform. XDR has been listed as the Trend No. 1 in Gartner top security and risk trend for 2020.

We are headquartered in Santa Clara, California.

We are looking for a Security Researcher or a Security Research Engineer with a passion on system security and data-driven security, who can invent new security detections, adopt machine learning models for detections, build big data pipeline for detections, and improve machine learning algorithms on correlating multiple detection signals to reconstruct the context of the attacks.


  • Research on different security problems based on demands, understand what data can be used to address the problems. Work with other teams on data collection.
  • Investigate different sources of data for security detection, such as authentication logs, cloud trails, SAAS application logs, endpoint data, network traffic. Research and propose efficient detection methods for various attacks.
  • Research and propose efficient detection algorithms with security domain knowledge, threat intelligence and machine learning. Implement the detection in products.
  • Design and implement red-team tools and attack test cases, to evaluate new detectors in products
  • Design and implement proper big data pipeline and machine learning infrastructure for detections and correlations
  • Research and propose efficient algorithms and systems to connect the dots, to correlate detection signals from various data sources, to build the context for sophisticated attacks.


  • Degrees in computer science, computer engineering, or information assurance. B.S./B.A. is required, and advanced degrees such as PhD or master are preferred.
  • Substantial hands-on experience with system security
  • Strong system design and implementation experiences
  • Experiences with data-driven security by analyzing diverse sources of data to identify security problems.
  • Experiences with applying machine learning in security is a big plus
  • Excellent verbal, writing, and interpersonal communication skills
  • Self-motivated with strong sense of ownership
  • The ability to work successfully in a high-energy, fast paced, rapidly changing environment
