Product Security Engineer (PSIRT - Product Security Incident Response Team)
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 are looking for a highly skilled PSIRT Engineer to lead the vulnerability response program for Replit’s cloud-native AI platform. You will own the lifecycle of security vulnerabilities affecting our products and services—from intake to validation, remediation coordination, and public disclosure.
This role requires strong technical ability to reproduce vulnerabilities, deep understanding of web/app/cloud exploit classes, and experience operating bug bounty and coordinated disclosure programs. You will work closely with Engineering, Cloud Security, SecOps, SRE, and IT teams to ensure vulnerabilities are fixed quickly and communicated responsibly.
What You’ll Do
Vulnerability Intake, Triage & Validation
Manage intake from bug bounty platforms (HackerOne preferred), customer reports, automated scanners, pentest reports, and coordinated disclosure channels.
Independently validate, reproduce, severity-score, and document findings.
Identify duplicates and maintain a clean vulnerability records pipeline.
Assess relevance and exploitability using OWASP, cloud misconfiguration patterns, and identity/authentication/authorization risks (Oauth, OIDC).
Remediation Coordination & SLA Management
Work with Engineering, SecOps, IT, SRE, and Cloud Security to confirm product impact and drive remediation.
Provide detailed reproduction steps, proof-of-concepts, and technical analyses.
Track SLAs, remediation progress, regression testing, and systemic improvements.
Support SOC 2, ISO 27001, and pentest evidence needs as part of vulnerability lifecycle governance.
Bug Bounty & Vulnerability Disclosure Program Management
Design and evolve the bug bounty program, including scope, rules, and reward structures.
Manage platform selection, private vs. public launches, and community engagement.
Communicate clearly with researchers, provide clarifications, and handle feedback or disputes.
Determine reward payouts, bonus decisions, and recognition for top contributors.
Coordinated Disclosure & CVE Management
Lead the coordinated vulnerability disclosure process for internal and external findings.
Negotiate disclosure timelines with researchers and partners.
Coordinate CVE assignments and publications, and prepare customer/public advisories.
Required Skills
Experience running or triaging for bug bounty programs (HackerOne ideally).
Strong ability to triage, validate, and reproduce vulnerabilities independently.
Deep understanding of web/app/cloud vulnerability classes, OWASP Top 10, misconfigurations, authN/Z issues, etc.
Familiarity with cloud platforms (GCP preferred) and SaaS architectures.
Strong understanding of CI/CD workflows, code structure, and software engineering fundamentals.
Nice to Have
Scripting or automation experience (Python, Go, Bash).
Pentesting background or exposure to offensive security work.
Familiarity with compliance frameworks such as SOC 2 and ISO 27001.
Experience authoring public advisories or CVE writeups.
Hands-on experience with SIEM, Cloud Logging, and investigative tooling.
