Job Description

Security Engineer – Detection & Response

Liftoff Mobile

• 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 (e.g. Prophet, Dropzone, or equivalent) 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 — 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.

Job Requirements

  • 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.
  • Demonstrated judgment in prioritizing security work using a risk-based approach.
  • Ability to quickly navigate large, unfamiliar codebases and reason about complex engineering systems.
  • Excellent verbal communication.
  • Willing to participate in an on-call rotation.

Benefits

  • Medical coverage
  • Wellness stipends
  • Additional perks based on your country of residence
