- Implement and maintain security controls aligned with SOC 2 and NIST principles.
- Support audits, risk assessments, and evidence collection activities.
- Define, maintain, and improve operational runbooks, monitoring, backup, and recovery processes.
- Mentor and provide technical guidance to system administrators and service desk staff.
- Partner with IT leadership on platform improvements, standardization, and roadmap planning.

The expected hiring compensation range for this position is $137,000 - $160,000 USD annually. Base pay offered may vary depending on multiple individualized factors, including market location, job-related knowledge, skills, and experience. The current bonus target for the position is 20% of the base salary with a stretch to twice the target, modified for corporate and individual performance.
