About the role

Security Engineer with incident response expertise to lead investigations from detection to root cause, coordinating containment across Security, SRE, and Engineering, while developing automation, playbooks, and platform hardening in a cloud-native environment.

Responsibilities

  • Serve as incident commander or technical lead for security incidents, from detection and triage through containment, eradication, recovery, and post-incident review.
  • Coordinate response across Security, SRE, Engineering, Legal, and leadership. Drive decisions under pressure and keep a clear record of actions taken.
  • Communicate incident status, impact, and risk clearly to technical and executive audiences.
  • Participate in and help shape the security on-call rotation.
  • Investigate suspicious activity across cloud infrastructure, containers, identity systems, and application layers using SIEM, Cloud Logging, telemetry, and host and container artifacts.
  • Determine scope, root cause, attacker behavior, and blast radius for confirmed incidents.
  • Quickly assess whether emerging threats apply to Replit, and whether we're already affected.
  • Build scripts, automations, and tools (Python, Go, Bash, or directly on Replit) that speed up response, such as automated enrichment, evidence collection, credential and session revocation, workload isolation, and alert triage.
  • Develop and maintain response playbooks and runbooks, and automate them where possible.
  • Integrate response workflows with SIEM, SOAR, ticketing, and chat tooling to cut time-to-contain.
  • Turn incident findings into new or improved detections, logging coverage, and visibility.
  • Lead blameless post-incident reviews and drive remediation items to completion.
  • Run tabletop exercises and simulations to test readiness and find gaps.

Qualifications

  • Proven experience leading or serving as technical lead on security incidents in a cloud or SaaS environment.
  • Strong hands-on investigation skills with SIEM, cloud audit logs, and log-based analysis. Comfortable working through large datasets under time pressure.
  • Proficiency writing production-quality scripts or tools in Python, Go, or Bash for investigation and automation.
  • Solid knowledge of cloud architecture and security, especially Google Cloud Platform (IAM, audit logging, GKE, networking).
  • Working knowledge of Kubernetes and containers, including how to investigate and contain compromised workloads.
  • Understanding of identity systems, SaaS architectures, and common cloud attack paths (credential theft, privilege escalation, supply chain, token abuse).
  • Familiarity with software engineering fundamentals, CI/CD pipelines, and package ecosystems, so you can work effectively with Engineering on code-level fixes.
  • Understanding of IR frameworks and lifecycle (for example NIST 800-61), plus the vulnerability lifecycle and exploitability analysis.
