As part of the team, this role builds and tunes detections, hunts for threats, and supports incident response to rapidly detect, contain, and remediate threats, and helps deploy, maintain, and optimize the security tools and controls that protect company and client data. The role also contributes to cloud security and the vulnerability management program and provides technical security support for audits and vendor reviews.

• Administer and improve security controls and system hardening (including Windows server and workstation security), and partner with IT and infrastructure teams on remediation and security architecture.


• Provide technical information security support for audits, risk assessments, and third‑party/vendor security reviews in partnership with the GRC team, and collaborate with teammates to share knowledge and improve processes.


• Other special projects and duties as assigned.

Minimum Requirements

• Bachelor’s degree in Information Security, Computer Science, Information Systems, or a related field (or equivalent experience).


• 5 to 8 years of experience in security engineering, security operations, incident response, and/or vulnerability management.


• Advanced knowledge of endpoint detection and response (EDR), cloud security (Azure/AWS/Microsoft 365), vulnerability management, incident response, and the MITRE ATT&CK framework, including deploying and maintaining security tooling across a hybrid (cloud and on‑premises) environment.


• Working knowledge of business‑related processes, procedures, terminology, and compliance.


• Analytical thinker with the ability to understand problems, determine root cause, and recommend appropriate solutions.


• Excellent verbal and written communication skills, able to relate complex concepts in a concise and easy‑to‑understand manner.
