In this role, you will:

• Participate in a 24/7/365 SOC, including rotating on-call coverage for overnights and weekends.
• Independently investigate and respond to complex security events across Linux, macOS, cloud, and Kubernetes environments.
• Determine the scope, impact, severity, and appropriate escalation path for potential security incidents.
• Coordinate containment and remediation activities with security, engineering, infrastructure, and operations teams.
• Utilize and query SIEM, EDR, and other security tools to identify suspicious activity and develop actionable findings.
• Create and improve detections-as-code, investigation procedures, automation, runbooks, and response workflows.
• Perform post-incident reviews and recommend improvements to security controls and response capabilities.
• Partner with threat intelligence and detection engineering teams to prepare for emerging threats and address gaps in coverage.
• Serve as an escalation point and mentor for junior engineers, providing guidance during investigations and reviewing their work.
• Lead scoped operational and technical improvement projects that increase the effectiveness and scalability of the SOC.

• 3–5+ years of experience in security operations, incident response, digital forensics, detection engineering, or a related field.

• Proficiency with modern security tools and platforms, including SIEM, EDR, IDS/IPS, and firewalls.
• Strong understanding of network protocols, VPNs, proxies, identity systems, and other security technologies.
• Experience developing or tuning security detections, preferably using detections-as-code.
• Ability to manage complex investigations, communicate risk clearly, and make sound decisions in high-pressure situations.
• Experience mentoring less-experienced engineers and collaborating effectively across teams and time zones.
• Degree in Computer Science, Computer Engineering, Cyber Security, Information Technology, or equivalent practical experience.

• Experience securing cloud infrastructure or large-scale production environments.
• Experience using Python or another scripting language to automate security workflows.
• Familiarity with incident response in Kubernetes-based infrastructure.
