A leading and long-established company in the industrial manufacturing sector is seeking a Senior Security Analyst to take ownership of its cybersecurity operations and help mature its overall security posture. This position reports to the Director of IT and will be the primary go-to for all things cyber — from endpoint protection to vulnerability management and awareness training.

What You'll Do

  • Lead daily security operations across endpoints, networks, and cloud systems.
  • Investigate and respond to potential threats, malware, and unauthorized activity.
  • Manage and improve vulnerability scanning, prioritization, and remediation processes.
  • Maintain and optimize endpoint and email protection tools.
  • Coordinate awareness training and security education initiatives company-wide.
  • Develop and maintain documentation around DR, security standards, and best practices.
  • Work cross-functionally with infrastructure and development teams to align systems with secure design principles.

What You Bring

  • 5+ years of IT security or cybersecurity experience, including incident response and vulnerability management.
  • Strong familiarity with tools such as CrowdStrike Falcon, Tenable Nessus, Proofpoint, or comparable platforms.
  • Understanding of frameworks such as NIST and general IT risk management.
  • Knowledge of Microsoft security stack and cloud identity platforms (e.g., Entra ID).
  • Certifications such as CISSP, CEH, or GSEC are an asset.
  • Excellent communication skills and the ability to work independently in a small, collaborative IT environment.

Why This Role

This is a pivotal position for a respected, innovation-driven organization looking to formalize its cybersecurity function. You'll have both the independence and the influence to shape security standards, implement leading tools, and work closely with a supportive IT leadership team that values modernization, collaboration, and operational excellence.
