Senior Corporate Security Systems Engineer in New York at Jobgether

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.

This is a hands-on security engineering opportunity focused on protecting and scaling a modern corporate technology environment.
You will own and improve critical security capabilities spanning endpoints, identity, SaaS applications, browsers, Zero Trust, and security monitoring.
The role combines security engineering, systems administration, automation, and continuous control validation.
You will turn security and compliance requirements into durable technical controls that are measurable, repeatable, and resilient to configuration drift.
A key focus will be reducing manual security operations through APIs, infrastructure-as-code, workflows, and intelligent automation.
You will collaborate closely with IT, Security Operations, GRC, and application owners while maintaining a strong security-first perspective.
Your work will directly strengthen organizational resilience, audit readiness, telemetry, and the overall security posture of a growing technology organization.

• 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.
