Explore high-impact Senior System Security and Information Assurance Engineer jobs and discover a career at the forefront of cybersecurity. Professionals in this critical senior role are the architects and guardians of an organization's most sensitive information systems. They design, implement, and manage comprehensive security frameworks to protect data integrity, confidentiality, and availability against evolving threats. This position is not merely about defense; it involves proactively building resilient systems that adhere to strict governance standards and enable secure business operations. Typically found within government contracting, defense, finance, and large enterprise sectors, these engineers translate high-level security policy into robust technical reality. The core responsibilities of a Senior System Security and Information Assurance Engineer are multifaceted. They commonly lead the implementation and management of enterprise-wide security solutions, such as Privileged Access Management (PAM), Identity, Credential, and Access Management (ICAM), and Zero Trust architectures. A central duty is enforcing the principle of least privilege, often through Just-In-Time access and credential vaulting, to eliminate standing privileges. These experts are responsible for integrating security tools across complex environments, ensuring seamless operation between identity providers, SIEM systems, and governance platforms. A significant portion of their work involves rigorous compliance, where they author critical documentation—System Security Plans (SSPs), Standard Operating Procedures (SOPs), and Low-Level Designs (LLDs)—to support Risk Management Framework (RMF) processes and achieve Authority to Operate (ATO) for systems. They also provide technical leadership, mentoring junior staff and collaborating with cross-functional teams to align security initiatives with business objectives. Candidates pursuing Senior System Security and Information Assurance Engineer jobs must possess a deep and specialized skill set. Typically, a bachelor’s or master’s degree in Cybersecurity, Computer Science, or a related engineering field is required, complemented by 8-10+ years of progressive experience in cybersecurity or systems engineering. Technical expertise is paramount, including hands-on proficiency with PAM/IGA solutions, identity federation protocols (SAML, OAuth), and scripting for automation and integration. A firm grasp of foundational frameworks like NIST SP 800-53, NIST 800-207 (Zero Trust), and DoD directives is essential. Industry certifications such as CISSP, CISM, or DoD 8570 IAT Level III (e.g., CASP+, CISSP) are standard requirements, validating both technical and managerial competence. For many roles, particularly those supporting national security, the ability to obtain and maintain a high-level government security clearance is a fundamental prerequisite. Successful professionals in this field blend sharp technical acumen with strategic vision, communication skills, and a meticulous approach to risk and compliance, making them invaluable assets in securing the digital landscape.
