Senior Cybersecurity Engineer / Architect

Our client is searching for a highly capable Senior Cybersecurity Engineer or Architect who can contribute across the full spectrum of an Enterprise Security Program. This role is ideal for someone who can move comfortably between strategy and execution—designing secure architectures, leading hands-on engineering, supporting operations, and strengthening security governance across on-prem and cloud environments. If you enjoy solving complex problems in a collaborative environment and want to make a measurable impact on enterprise risk reduction, this is your lane.

This position requires a cybersecurity professional with demonstrated experience across the four major security pillars: Application Security, Security Engineering, Security Operations, and GRC. You should be able to connect technical decisions to business outcomes and ensure security controls work cohesively across identity, endpoint, network, and cloud domains.

Term: Contract to hire
Location: Monrovia, CA (Hybrid with remote options available)
Compensation: $75–$80/hour
Work Authorization: No visa sponsorship available. No C2C.

What You’ll Do

• Design, implement, and support enterprise-wide security solutions across cloud and on-premise environments, covering identity, endpoint, network, and data security.
• Serve as a technical escalation point while collaborating closely with IT infrastructure, DevOps, cloud, and application teams to embed security into system design and daily operations.
• Lead improvements across the enterprise security pillars: maturing AppSec practices, strengthening security engineering controls, improving SecOps workflows, and supporting key GRC initiatives.
• Enhance perimeter, internal, and email security while optimizing SIEM/SOC alerting, detection logic, dashboards, and incident response processes.
• Support investigation and incident response activities, ensuring integration between monitoring tools, playbooks, and escalation paths.
• Continuously evaluate and improve security tooling, processes, and architecture to raise overall cyber resilience and reduce business risk.

What Gets You the Job

• 7+ years of hands-on cybersecurity experience spanning multiple domains: identity, endpoint, network, cloud, AppSec, incident response, and governance.
• Proven experience operating within an Enterprise Security Program across AppSec, Security Engineering, SecOps, and GRC.
• Strong background designing and operationalizing enterprise-level security controls across hybrid environments.
• Demonstrated ability to secure internal networks and endpoints with strong visibility, detection, and prevention measures.
• Hands-on expertise in identity and access management, email security technologies, and modern authentication frameworks.
• Practical experience integrating, tuning, and optimizing SIEM/SOC platforms and improving response workflows.
• Strong collaboration skills and the ability to work with infrastructure, cloud, and application teams to embed security early and often.
