About the Role:

Zenity is looking for a Senior Product Security Engineer to own and evolve our Application and Cloud Security programs end-to-end. You'll embed security early in the development lifecycle, drive automation-first security practices across engineering, and partner closely with DevOps and product teams to keep our platform secure by design - from code to cloud.

Responsibilities:

• Own, maintain, and continuously improve the Secure Design Review process, ensuring security considerations are integrated early in the development lifecycle.
• Develop, implement, and maintain Zenity's Application Security Program, including controls, standards, developer enablement, and automation - managing SAST and DAST tooling, integrations, alerting, and program-wide reporting.
• Develop and maintain Zenity's Cloud Security Program, defining guardrails, policies, and automated controls for secure-by-default cloud deployments, including CSPM tooling, findings triage, and alignment with internal risk and compliance processes.
• Monitor and enforce SDLC security controls, ensuring consistent application of secure development practices across all engineering teams.
• Partner with DevOps to design, implement, and maintain a fully secured CI/CD pipeline, embedding security checks, guardrails, and automated gates throughout build, test, and deployment stages.
• Collaborate closely with engineering teams to deliver actionable guidance, model threats, advise on architecture, and support secure implementations.
• Identify gaps in product, application, and cloud security posture, and drive end-to-end remediation and vulnerability management campaigns.
• Define and track KPIs, metrics, and reporting for application and cloud security health.
• Drive automation-first approaches to product and cloud security, reducing friction and enabling fast, safe development, while promoting a culture of security and developer empowerment.

Requirements:

• 5+ years of experience in Engineering / Security Engineering, including 3+ years in an Application Security or Product Security focused role.
• 2+ years of experience managing enterprise-wide security projects, with strong project planning and organizational skills.
• Proven experience leading AppSec-focused Security Review programs and CloudSec-focused Secure Design reviews.
• Hands-on experience owning the migration or deployment of AppSec tooling (SAST, DAST, ASPM, or similar).
• Strong proficiency with Kubernetes, Helm, and Terraform.
• Strong proficiency with Python and TypeScript.
• A builder's mindset - comfortable developing in-house solutions when faced with a capability gap.
