Position Summary

The GRC Automation & Continuous Controls Monitoring (CCM) Senior Cybersecurity Engineer is a strategic and technical role, responsible or helping turn GRC into a trust engine for the business: reducing audit friction, improving business risk exposure visibility, accelerating evidence readiness, and enabling stronger operational confidence. The role serves as the technical focal for GRC automation, developing automated evidence collection, control testing, risk intelligence, and AI-enabled governance capabilities across cloud, on-premises, identity, operational technology (OT), and security platforms. The role collaborates closely with Cyber Fusion, Enterprise Architecture, and Cyber Engineering, to design and build deterministic control-testing logic where deterministic approaches are enough; and AI agents and LLM-backed workflows where reasoning, summarization, or judgment is required, such as evidence-to-control mapping, attestation drafting, drift detection, and audit-package assembly. This position belongs to a family of jobs with increasing responsibility, competency, and skill level. Actual position title and pay grade will be based on the selected candidate’s experience and qualifications.

Key Responsibilities

• Conducts detailed analyses on changes to cybersecurity solutions and its relationship to internal and external systems to assess control effectiveness and cybersecurity risk. Resolves complex multi-functional technical issues.
• Leverages cybersecurity assessments, standards, control testing methodologies, and compliance frameworks to ensure compliance across security systems.
• Improves the efficiency and effectiveness of Security solutions, governance processes, automated controls, and monitoring capabilities.
• Analyzes existing processes and procedures and leads efforts for implementing improvements, automation opportunities, or remediation activities.
• Responsible for development and submission of Standard Operating Procedures.
• Analyzes business impacting events, performs initial investigation, and evaluates control performance, exceptions, and risk indicators through continuous monitoring activities.
