Senior Corporate Security Systems Engineer

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior Corporate Security Systems Engineer based in United States.

• Own, deploy, configure, integrate, monitor, and continuously improve enterprise security technologies across EDR, SIEM, MDM, Zero Trust, identity, browser security, and SaaS environments.
• Establish secure configuration baselines for corporate systems and continuously identify, measure, and remediate configuration drift.
• Build API-driven, infrastructure-as-code, scripting, and workflow automations that reduce repetitive security operations and improve the consistency of control enforcement and evidence collection.
• Partner with Corporate IT and application owners to securely deploy and operate endpoints, applications, and SaaS platforms while maintaining appropriate security boundaries and technical controls.
• Improve security telemetry by integrating corporate applications and systems with centralized monitoring and ensuring relevant signals for vulnerabilities, misconfigurations, and suspicious activity are available and actionable.
• Translate security and compliance requirements, including CMMC 2.0 and NIST-aligned controls, into practical technical implementations that can be continuously validated and supported with defensible evidence.
• Serve as a trusted technical owner for key components of the corporate security stack, maintaining a clear understanding of architecture, configuration, integrations, and security posture.
• Identify systemic security weaknesses and implement durable solutions rather than addressing individual findings in isolation.
• Improve the reliability and coverage of security controls and telemetry while reducing the manual effort required for audits, assessments, and recurring compliance activities.
• Work cross-functionally to communicate security risks, evaluate proposed configurations, and implement practical controls without losing sight of core security objectives.

• 4+ years of hands-on experience in security engineering, enterprise security, systems security, or a closely related technical discipline.
• Demonstrated experience securing identity, SaaS, endpoint, or Zero Trust environments and understanding how configuration decisions influence enterprise security.
• Hands-on experience with security automation using REST APIs, webhooks, workflow automation platforms, infrastructure-as-code, scripting, or configuration-management technologies.
• Experience deploying, administering, or owning endpoint security and detection technologies such as EDR and SIEM platforms, including integrating security telemetry into centralized monitoring.
• Experience administering MDM or endpoint-management platforms and enforcing secure configurations and endpoint baselines.
• Strong ability to assess technical requirements from a security perspective, identify risks in proposed configurations, and collaborate effectively with technical teams to implement practical controls.
• Familiarity with enterprise security technologies such as CrowdStrike, Zscaler, Workspace ONE, Okta, Splunk, or comparable platforms.
• Experience implementing or supporting controls aligned with CMMC 2.0, NIST 800-53, CIS, STIGs, or similar security frameworks is highly valued.
• Experience integrating SaaS and security platforms through REST APIs, webhooks, GitHub Actions, Okta Workflows, or comparable automation technologies is preferred.
• Background securing regulated, government, defense, or other high-assurance corporate environments is a plus.
• Strong problem-solving, communication, collaboration, and technical ownership skills, with the ability to work independently while partnering effectively across teams.

• Remote-friendly work environment designed to support distributed teams.
• Opportunities to work on consequential security challenges involving enterprise systems, automation, Zero Trust, and high-assurance environments.
• Professional growth through exposure to evolving security technologies, compliance frameworks, and modern security engineering practices.
• Opportunity to make a measurable impact on security resilience, automation, continuous control validation, and audit readiness.
• Collaborative environment with cross-functional exposure to Corporate IT, Security Operations, GRC, and application teams.
• Access to a broad and evolving technology ecosystem spanning endpoint security, identity, SIEM, MDM, SaaS security, Zero Trust, and automation.
