Job Description

We are seeking a Senior Cyber Defense Infrastructure Engineer to ensure the reliable operation, performance, and lifecycle management of enterprise information security tooling. This role is critical to maintaining the availability and effectiveness of the platforms that protect the organization’s systems, data, and users.

Security tooling is only effective when it is operationally sound. In this role, you will directly enable the organization’s cyber defense capabilities by ensuring critical security platforms are resilient, scalable, and reliable—supporting everything from threat detection to incident response.

You will serve as the operational owner for core security platforms, working closely with Security Architecture, Security Operations, Cloud Engineering, and IT teams to ensure tools are properly deployed, integrated, maintained, and ready to support detection and response activities at scale.

In this role, you will be responsible for....

• The implementation, configuration, and operational readiness of security tooling after tool selection has been approved. Tool strategy, vendor selection, and control design are owned by Security Architecture and leadership functions.

• Security Tool Deployment & Operationalization:
• Lead the post‑selection deployment, configuration, and operationalization of enterprise security tools in alignment with approved architectures and standards
• Implement baseline configurations, integrations, and scaling required to bring new security platforms into production‑ready operational state
• Partner with Security Architecture and platform teams to operationalize approved tool designs, ensuring reliability, availability, and supportability
• Develop monitoring, runbooks, and operational processes to support secure and reliable ongoing operations following rollout
• Platform Management & Engineering:
• Configure, maintain, patch, and upgrade security tools in alignment with architectural standards
• Manage security tool lifecycles, including scaling, optimization, and decommissioning
• Implement and maintain integrations with cloud platforms, identity systems, logging pipelines, and operational tools
• Operational Excellence & Governance:
• Develop and maintain operational documentation, runbooks, and support procedures
• Partner with incident response teams to ensure tools are fully operational during security events
• Support audits and assessments by demonstrating tooling configuration, availability, and operational controls
• Collaboration & Continuous Improvement:
• Work closely with Security Architecture to operationalize new tooling and designs
• Collaborate with Security Operations teams to support detection and response capabilities
• Identify opportunities to improve tooling reliability, automation, and operational efficiency

What you will need to succeed...

• 5+ years of experience supporting or engineering enterprise security platforms
  Hands‑on experience with one or more of the following:
• Endpoint protection / EDR tools
• SIEM or security analytics platforms
• Vulnerability management solutions
• Cloud or infrastructure security tooling
  Strong understanding of:
• Linux and/or Windows systems
• Cloud environments (AWS, Azure, or hybrid)
• System integrations, logging, and telemetry pipelines
• Experience working within change, incident, and problem management processes

It would be a plus if you had this experience...

• Experience in large‑scale or regulated enterprise environments
• Familiarity with security frameworks such as NIST CSF, CIS Controls
• Experience supporting SOC or incident response teams
• Relevant certifications (preferred but not required), such as cloud or security certifications

What you can expect from us:
• Base annual salary target: $120000 - $150000 (yes, we do have flexibility if needed)
• Opportunity for annual cash bonus
• Health / Dental / Vision Benefits Day-One
