Job description

• 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 be the person who takes charge when something goes wrong. You’ll 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
• You’ll write the scripts, automations, and tooling that take manual work out of triage, evidence collection, and containment. You’ll also turn lessons from each incident into better detections, playbooks, and platform hardening
• 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 (0-days, active exploitation campaigns, bug bounty findings, customer reports) 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
