Liftoff; Reedley (CA); Remote; USD 184,000 - 250,000; Full time

Job summary

Liftoff is seeking a Senior Security Engineer to own and advance the SIEM, detection content, and incident response programs. You will champion AI-augmented SOC tooling, triage alerts, and coordinate with Engineering and IT to scale security across cloud, infrastructure, and applications.

The role emphasizes hands-on coding for security automation, robust runbooks, and reports. It offers remote work within the US with competitive compensation and benefits.

Qualifications

• 5+ years in security engineering, security operations, detection engineering, or software engineering with a security focus.
• Hands-on production SIEM operation — onboarding log sources, writing and maintaining detection content, and triaging alerts.
• Write production-quality code for security automation and detection-as-code.
• Experience leading or substantially contributing to security incident response.
• Strong technical writing — design docs, runbooks, and post-incident reviews.

Responsibilities

• Own day-to-day operation of Liftoff's SIEM (Panther) — log source ingestion, detection content, and the alert investigation pipeline.
• Lead Liftoff's adoption of AI-augmented SOC tooling as a multi-year modernization investment.
• Triage incoming security alerts and drive timely investigation and remediation with stakeholders across Engineering and IT.
• Lead incident response — investigation, containment, and post-incident review — and mature processes and runbooks so response becomes predictable and repeatable.
• Build tooling and automation that detects active threats, enriches alerts, and reduces manual investigation toil.
• Partner with Engineering and IT to make detection and response self-service where possible — clear log-onboarding paths, documented detection proposals, accessible runbooks.
• Close the feedback loop between offensive findings and detection coverage.
• Partner across the security team on cloud, infrastructure, and application security work alongside detection focus.
• Participate in the Security team's on-call rotation and incident response.
