Staff Security Engineer, PSIRT

Who is Flock? Every community deserves to be safe, it’s a fundamental right. Our mission is simple - to build technology that reduces crime and protects privacy. Flock partners with cities, businesses, schools, and neighborhoods to help protect where people live, work, and play. Last year, Flock technology supported over 1 million criminal investigations. We've also helped solve approximately 20% of reported crimes in areas where we're deployed, and have played a role in locating more than 10,000 missing people. We are a high-performance team united by urgency, ownership, and a shared commitment to meaningful impact. The work is fast-paced and the expectations are high. We push beyond perceived limits, support each other, and hold ourselves accountable to delivering results that matter. With over $1B in funding and an $8.3B valuation, we are scaling with intention and investing in the people who will help us build what others said could not be done. At Flock, you will find the opportunity to grow quickly, take on real responsibility, and contribute to something bigger than yourself. The Opportunity As a Staff Security Engineer, PSIRT Lead , you will stand up and run Flock's Security Incident Response Team (PSIRT) as the single point of accountability for every externally-reported and internally-discovered vulnerability that touches a Flock product. Coordinating with teams about fixes happens as much as coordinating with your security counterparts for security validation. You will be the operational owner of our newly established CNA, the technical owner of our Coordinated Vulnerability Disclosure (CVD) program, and the cross-functional coordinator who drives fixes to closure across Hardware, Firmware, Device SRE, Cloud SRE, Mobile, ML, Legal, Comms, and Customer Support. This is an individual contributor role with no direct reports. You will lead by influence across engineering, legal, communications, and support, setting the SLAs, the metrics, the playbooks, and the public security advisories that the rest of the company executes against. While you will partner closely with our Detection & Response team and Corporate Security, PSIRT is distinctly product-focused: every cycle you spend should reduce risk for the devices in the field and the customers who depend on them. The Skillset 7+ years in security engineering with at least 4 years directly running or leading a PSIRT, product security, or coordinated vulnerability disclosure function. Experience at a company that ships connected hardware (LPR/IP cameras, ICS/OT, automotive, medical, or networking gear) is highly preferred. Demonstrated end-to-end ownership of the FIRST PSIRT Services Framework v1.1 service areas (Stakeholder Ecosystem, Discovery, Triage, Remediation, Disclosure). You can talk credibly about how you implemented each in a previous role. Hands-on operational experience acting as a CVE Numbering Authority (CNA) or leading the technical onboarding of one. Deep knowledge of CNA Operational Rules v4.x, CVE scope definition, and root coordination (CISA ICS-CERT, MITRE). Deep familiarity with ISO/IEC 29147 (disclosure), ISO/IEC 30111 (handling), the CERT/CC Guide to CVD, and CISA Binding Operational Directive 20-01. Strong technical understanding across product security, with deep operational experience in at least three of the following (areas 1 and 2 are highly prioritized): Embedded/Firmware Security (Secure boot, hardware root of trust, UART/JTAG/USB attack surfaces, OTA integrity). Linux/Android Device Security. Cloud Security on AWS (IAM, EKS, federation, secrets management). Mobile/Web App Security (OWASP Top 10, GraphQL, authn/authz). ML/CV Model Security (Adversarial inputs, data poisoning, extraction). Fluent with CVSS v3.1/v4.0, CWE classification, EPSS, and SSVC frameworks. You can defend a severity decision in front of an engineering VP and an external researcher in the same week without changing your story. Exceptional written skills. You can draft a sharp, customer-facing security advisory, a precise CVE record, an internal postmortem, and a board-level executive summary of the same event—tailoring the tone perfectly to each audience. Ability to obtain and maintain CJIS certification as a condition of employment. Feeling uneasy that you haven’t ticked every box? That’s okay; we’ve felt that way too. Studies have shown women and minorities are less likely to apply unless they meet all qualifications.
