About The Position

The Senior Security Engineer directs the architecture, integration, deployment, operation, and sustainment of security tools, sensors, platforms, data sources, and supporting infrastructure across on-premises and cloud environments. The role translates mission and security needs into implementable designs, leads technical change, maintains engineering standards and documentation, and guides engineers and platform administrators through complex delivery and troubleshooting work. The engineer supports SOC technologies and ensures solutions align with customer policies, technical standards, hardening requirements, and approved architecture. The role also enables detection and automation teams by ensuring telemetry, APIs, integrations, permissions, and platform capabilities are available and reliable. The position is in a hybrid federal customer environment, with regular onsite presence and periodic travel between supported operating locations potentially required. Work takes place during core business hours, with participation in planned maintenance, change implementations, and after-hours response to major platform issues. An active Secret clearance and ability to pass a minimum background investigation are required.

Requirements

Seven or more years of cybersecurity engineering experience.
Experience developing and implementing cybersecurity solutions that protect systems, networks, applications, and cloud environments.
Experience evaluating new technologies, investigating solution issues, validating complex systems, and testing security products for weaknesses.
Experience translating business and security requirements into technical designs and engineering documentation.
Demonstrated ability to lead cross-functional engineering work and communicate with technical and nontechnical stakeholders.
Bachelor's degree in cybersecurity, computer science, information systems, engineering, or a related field; additional relevant experience may be considered in lieu of a degree.
Active Secret clearance required.
Ability to pass a minimum background investigation.

Nice To Haves

Five or more years engineering enterprise SOC platforms such as SIEM, SOAR, EDR, NDR, threat-intelligence, case-management, or log-pipeline technologies.
Experience integrating security tooling across on-premises, AWS, Azure, or Microsoft 365 environments.
Experience presenting changes through a formal change-control process and carrying solutions from design through implementation and operational acceptance.
CISSP or CISSP-ISSEP; GCIA, GCED, GSEC, GCDA, cloud-security, or platform-specific architecture certifications are valuable.
Experience with security baselines, vulnerability remediation, cryptographic requirements, identity services, and technical documentation for regulated environments.

Responsibilities

Lead security architecture, strategy, research, evaluation, prototyping, integration, deployment, and sustainment activities for SOC technologies.
Design, deploy, configure, operate, maintain, and troubleshoot security tools, sensors, analytics platforms, data pipelines, and supporting infrastructure.
Ensure engineered solutions align with customer policies, technical standards, hardening requirements, and approved architecture direction.
Lead integration and interoperability among tools, sensors, data sources, platforms, workflows, applications, and cloud services.
Translate security and operational requirements into technical designs, implementation plans, test approaches, configurations, and support models.
Prepare and review architecture diagrams, engineering design documents, configuration information, deployment records, test plans, and operational handoff materials.
Coordinate technical changes through established change-management processes and verify readiness before production implementation.
Maintain awareness of asset, license, maintenance, support, certificate, and lifecycle dependencies that affect platform availability and supportability.
Enable detection and automation teams by ensuring required telemetry, APIs, integrations, permissions, and platform capabilities are available and reliable.
Develop and maintain engineering standards, reusable patterns, secure configurations, operating procedures, and technical knowledge content.
Lead knowledge transfer and technical mentoring for engineers, administrators, analysts, and customer personnel.
Participate in planned maintenance, change implementations, and after-hours response to major platform issues.
Travel periodically between supported operating locations as required.
