  • Collaborate with the security engineering and security operations center (SOC) teams to integrate new threat intelligence and enhance existing security tools and controls.
  • Mentor junior analysts and contribute to the ongoing improvement of the organization's overall security posture.

What you will need to succeed...

  • Education: Bachelor's degree in computer science, Cybersecurity, Information Technology, or a related field.
  • Certifications: Preferred certifications GCIH (GIAC Certified Incident Handler) and CompTIA CySA+ (Cybersecurity Analyst+) certification
  • Proven, hands-on experience using platform for EDR (Endpoint Detection and Response) and threat hunting.
  • Expert-level knowledge of PowerShell Scripting, Python and EDR and SIEM query language is preferred.
  • Deep understanding of incident response lifecycles, methodologies, and forensic techniques.
  • Strong knowledge of networking protocols, operating systems (Windows, Linux, macOS), and common attack vectors.
  • Familiarity with scripting languages (e.g., Python, PowerShell) for automation of hunting tasks is a plus.
  • Exceptional analytical and problem-solving skills with keen attention to detail with the ability to work independently with minimal supervision and manage multiple investigations simultaneously.
  • Strong communication skills, capable of presenting complex technical information clearly to both technical and non-technical audiences.
  • A proactive mindset and a passion for continuous learning in the rapidly evolving field of cybersecurity.

Location: We are looking for someone who is driving distance to our Westbrook, Maine HQ with the expectation of a minimum of 8 days on-site per month. We would also consider candidates willing to relocate to Maine or candidate in the New England area (NH or MA ) that can travel to HQ occasionally.
