## About the Role

* Experience: 5+ years of dedicated Security Engineering experience, ideally within a high-growth SaaS, E-commerce, or Fintech environment.
 * SaaS Deep-Dive: The ability to dive deep into the business logic of a complex SaaS application to uncover and verify elusive attack vectors.
 * Web and API Security Mastery: a deep understanding of web/API attack vectors and scalable best practices and how to run workloads securely in a cloud environment (k8s, AWS/GCP/Azure)
 * Ownership: A proven track record of autonomously driving security initiatives from conception to completion.
 * Automation Mindset: Proficiency in at least one programming language for scripting and security tool development (bonus points for automating GRC evidence collection).
 * Education: A Bachelor's or Master's degree in Computer Science, Cybersecurity, IT, or a related technical field (or equivalent practical experience).
Preferred:

 * Experience navigating PCI DSS script security.
 * A background in Red/Purple Team operations and advanced penetration testing, paired with the empathy and collaboration skills needed to help dev teams fix software vulnerabilities.
 * Hands-on experience with Terraform for securing infrastructure-as-code and integrating security testing.
 * Familiarity with our modern tech stack: GCP, Golang, and TypeScript. Why join vivenu?

## Description

* Modern Technology Stack: Dive into securing a massive TypeScript monolith alongside Go supporting services, giving you hands-on experience in modern language security and advanced GitHub CI/CD pipeline hardening.
 * Web and API: secure the application of the vivenu platform which provides customers with an out-of-the-box ticketing software as well as the underlying API structure
 * Complex Multi-Cloud Architecture: Challenge your skills against a sophisticated multi-tenant, multi-region environment spanning k8s, GCP (our primary compute) and and separate database services
 * Cutting-Edge Deployment: Secure a next-gen Kubernetes "satellite architecture" utilizing hardened private compute nodes, VPC peering, and Argo CD for GitOps-a true, modern cloud-native security mandate.

As a Senior Security Engineer - AppSec (d/f/m) your responsibilities will include:

 * Be a Trusted Advisor: Partner closely with engineering teams to champion security-by-design and elevate our overall security posture.
 * Offensive & Defensive Testing: Coordinate and execute threat modeling and advanced security tests across our product and underlying infrastructure.
 * Lead Next-Gen Vulnerability Management: Drive triage and remediation using modern, risk-based principles like EPSS, while leveraging AI technologies to accelerate security testing at scale.
 * Pioneer Security-as-Code: Design, implement, and automate security checks and guardrails (SAST, DAST, and secret scanning) directly into CI/CD pipelines.
 * Review & Refine: Perform deep-dive code and configuration reviews, advocating for secure coding practices that support a proactive shift-left strategy.
