As a Sr. Staff Security Engineer, you will play a critical role in safeguarding our Federal environments by designing, implementing, and managing advanced security detection and monitoring solutions.

  4. Conduct threat hunting and root cause analysis to mitigate risks.
  5. Ensure compliance and security standards in all detection activities.

Minimum Qualifications

  1. 8+ years of experience in security engineering or operations, with flexibility for candidates with exceptional skills.
  2. Proficiency in managing an Elastic Stack (ELK) for security event analysis and detections.
  3. Strong experience with cloud security tools like AWS, Azure, or Google Cloud.
  4. Proven ability in security detection engineering and independent problem-solving.
  5. Bachelor’s degree in Cybersecurity, Computer Science, or related field, or equivalent experience.

Preferred Qualifications
