Security Engineer - Incident Response
Replit · Foster City, CA
About this role
## About Replit Replit is the agentic software creation platform that enables anyone to build applications using natural language. With millions of users worldwide, Replit is democratizing software development by removing traditional barriers to application creation. ## About the Role We’re looking for a **Security Engineer** with deep **incident response** experience to help defend Replit—a fast-moving, cloud-native AI vibe-coding platform. You’ll take charge when something goes wrong: lead investigations from first signal to root cause, coordinate containment across **Security, SRE, and Engineering**, and keep stakeholders informed while the incident is moving fast. This isn’t a pure responder role. We want a well-rounded security engineer who has run real incidents and wants to make the next one faster—by writing scripts, automations, and tooling that reduce manual work in triage, evidence collection, and containment. You’ll also turn lessons learned into better detections, playbooks, and platform hardening. ## Responsibilities ### Incident Response - 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. ### Investigation & Forensics - Investigate suspicious activity across cloud infrastructure, containers, identity systems, and application layers using **SIEM, Cloud Logging, telemetry**, and host/container artifacts. - Determine scope, root cause, attacker behavior, and blast radius for confirmed incidents. - Quickly assess whether emerging threats (0-days, active exploitation campaigns, bug bounty findings, customer reports) apply to Replit—and whether we’re already affected. ### IR Automation & Tooling - Build scripts, automations, and tools (Python, Go, Bash, or directly on Replit) to speed up response, including automated enrichment, evidence collection, credential/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. ### Detection & Continuous Improvement - 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. ## Required Skills & Experience - Proven experience leading or serving as technical lead on security incidents in a cloud or SaaS environment. - Strong hands-on investigation skills with **SIEM** and **cloud audit logs**; comfortable working through large datasets under time pressure. - Proficiency writing production-quality scripts/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 investigating and containing compromised workloads. - Understanding of identity systems, SaaS architectures, and common cloud a
