Senior Security Engineer

The Senior Security Engineer is responsible for designing, implementing, and governing NEMS enterprise security architecture across all clinic sites, data center environments, and cloud infrastructure. Operating within a hybrid multi-site environment spanning multiple hosting locations with defined security SLAs aligned to HIPAA and NIST standards, this role serves as a hands-on technical leader who collaborates with external security vendors, cloud providers, and internal infrastructure teams to architect and enforce a cohesive, Zero-Trust security environment. The Senior Security Engineer plays a critical role in IAM governance, endpoint protection, lifecycle management, security policy development and enforcement, SOC coordination, and continuous compliance monitoring across endpoints and data centers.
