Liftoff The Security Engineer, Detection & Response at Liftoff leads the development and enhancement of the detection and response function, including AI-augmented SOC tooling. This role involves hands-on technical work across infrastructure, web, mobile, and IT security.

Responsibilities

Own day-to-day operation of Liftoff s SIEM (Panther) — log source ingestion, detection content, and the alert investigation pipeline.

Triage incoming security alerts and drive timely investigation and remediation with stakeholders across Engineering and IT.

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 — so security scales without becoming a bottleneck.
Close the feedback loop between the team s offensive and proactive findings and detection coverage.
Partner across the security team on cloud, infrastructure, and application security work alongside your detection and response focus — every engineer on this team covers breadth beyond their primary focus.
Participate in the Security team s on-call rotation and incident response.
