Security Engineer

Celtic Bank is seeking a skilled Security Engineer to help protect the Bank’s systems, data, and technology environment. This role is responsible for identifying, reducing, and continuously managing internal and external security risks while leading key security initiatives across identity, network, endpoint, and cloud environments.

The Security Engineer will administer critical security platforms, maintain a consolidated technology asset inventory, and lead projects involving modern desktop authentication, Secure Access Service Edge (SASE), Cloud Access Security Broker (CASB), and SaaS Security Posture Management (SSPM). This position will also support incident response activities and help continuously strengthen the Bank’s overall security capabilities.

What You’ll Do

• Administer, configure, and maintain the Rapid7 attack surface management platform, including discovery scope, scan configuration, and exposure triage.
• Build and maintain a consolidated asset inventory using the attack surface management tool, reconciling discovered assets against authoritative systems of record.
• Own cyber asset attack surface management (CAASM), correlating asset, vulnerability, and tool-coverage data to identify unmanaged, unprotected, or misconfigured assets.
• Lead the modern desktop authentication project, implementing two-factor authentication for endpoint sign-in across the environment.
• Lead the Secure Access Service Edge (SASE) conversion project, including design, phased rollout, policy definition, and migration from legacy network access controls.
• Lead the cloud access security broker (CASB) and SaaS security posture management (SSPM) projects, establishing policy, monitoring, and remediation workflows for sanctioned and unsanctioned cloud applications.
• Maintain CrowdStrike endpoint protection, including sensor deployment and health, policy tuning, detection triage, and coverage reporting.
• Maintain the Dashlane enterprise password management platform, including provisioning, group and sharing standards, and adoption reporting.
• Support incident management and response, including investigation, containment, and post-incident remediation for endpoint, identity, and cloud events.
• Track and report security posture metrics, including asset coverage, attack surface exposure, two-factor enrollment, and project milestones, to IT and security leadership.
• Develop and maintain technical documentation, including tool configurations, project designs, operational procedures, and runbooks.

Requirements

• Bachelor's degree in Information Technology, Computer Science, Information Security, or a related field, or equivalent combination of education and experience; security certifications (e.g., Security+, CySA+, SSCP) preferred.
• 3–5 years of hands-on experience in information security or enterprise IT, with a focus on attack surface, endpoint, and identity security.
• Demonstrated experience administering an attack surface management platform (Rapid7 or comparable) and building asset inventory from discovery data.
• Experience with endpoint detection and response tooling, preferably CrowdStrike, including policy configuration, sensor health, and detection triage.
• Working knowledge of SASE, CASB, and SSPM concepts, with experience supporting or leading the deployment of at least one.
• Experience implementing multi-factor authentication for endpoint or workstation sign-in, and familiarity with enterprise password management platforms such as Dashlane.
• Understanding of information security principles, data classification, and regulatory requirements applicable to financial institutions (e.g., GLBA, FFIEC, ISO 27001).
• Experience participating in incident response, including investigation, containment, and remediation, and the ability to lead technical projects across multiple teams.
• Strong analytical, troubleshooting, and documentation skills, with the ability to communicate technical concepts clearly to both technical and non-technical audiences.
