A key focus of the position is to secure on-premises and cloud-based workloads, as well as IT operations that support employees. Responsibilities

Secure on-premises and cloud-based workloads, along with IT operations supporting employees. Lead strategic security initiatives such as Zero Trust, threat modeling, and security automation. Evaluate and recommend cutting-edge tools, technologies, and practices to advance security posture. Perform technical risk assessments and architecture reviews for new and existing systems. Serve as a technical advisor during incident response, supporting complex investigations and root cause analysis. Collaborate with DevOps and Infrastructure teams to embed security into CI/CD pipelines, cloud environments, and infrastructure-as-code. Ensure compliance with regulatory frameworks (NIST, ISO 27001, SOC 2, PCI-DSS, HIPAA, GDPR). Mentor and guide junior security engineers and analysts, fostering skill growth and knowledge sharing. Develop clear documentation, threat models, diagrams, and reports for technical and business stakeholders. Stay informed on emerging security threats, vulnerabilities, and trends; recommend proactive countermeasures. Qualifications

Advanced knowledge of security architecture, encryption, authentication, and cloud security (AWS, Azure, GCP). Practical experience with firewalls, IDS/IPS, endpoint protection, DLP, IAM, SIEM, and vulnerability management. Familiarity with scripting (Python, PowerShell) and automation tools (Terraform, Ansible). Security certifications such as CISSP, CCSP, OSCP, or GIAC strongly preferred. Excellent analytical, problem-solving, and communication skills. Working Conditions
Must be able to perform essential job duties. Work is performed primarily in an office environment. Typically requires the ability to sit for extended periods of time (66%+ each workday), hear the telephone, and enter data on a computer and may also require the ability to lift up to 10 pounds.
