Serving as a subject matter expert in security architecture to include providing advice to Program Managers, Customer technical experts, and internal program teams.
Continuously improve engineering processes, documentation standards, implementation playbooks, migration runbooks, technical standards, and execution models to accelerate delivery, reduce rework, improve operational handoff, and lower sustainment burden.
Multi-Cloud Security Architecture: Design security architectures and solutions spanning AWS, Azure, GCP, and OCI, identifying common architectural patterns while accounting for CSP-specific capabilities and limitations. Security Platform Integration: Architect integrations between native security services and enterprise security platforms, including vulnerability management products, Stig evaluation, and SIEM.
Containers & Kubernetes: Knowledge of Kubernetes and container security architectures, including image security, admission controls, secrets, identity, network policies, software supply chain security, security scanning, and runtime protection.
Design, engineer, and implement enterprise network security architecture spanning next-generation firewalls, intrusion detection and prevention, web and TLS proxies, VPN and encryption services, network access control, DNS security, and east-west security controls.
Evaluate the current network security architecture, identify gaps and improvement opportunities, estimate level of effort, assess implementation risk, and develop practical engineering plans to strengthen enterprise security capabilities.
Provide specifications for network security architecture, evaluate and recommend emerging security technologies, and perform needs assessments to inform design and investment decisions.
Tune and optimize security controls to reduce false positives, close coverage gaps, and improve detection and enforcement without degrading network performance or availability.

To be successful in this role you need these skills (required):

Clearance: Active or current Top Secret/SCI and the ability to obtain Polygraph
Bachelor of Science degree from an accredited university ideally in Computer Science, Information Assurance, Information Security System Engineering or related field with a minimum of 12 years of experience as an Information Systems Security Engineer (ISSE) or System Engineer on programs and/or contracts with the customer space.
