## Job description

Redefine the future of live entertainment tech

Welcome to vivenu, the global leader in event ticketing tech and one of the world’s fastest-growing live entertainment tech firms. We are transforming event ticketing for global leaders like the Grammys, the Golden Globes, Stanford University and the Hockenheimring turning what was once a simple transaction into a strategic business advantage. Backed by over $65 million in funding, our platform empowers event organizers to own their brand experience, unlock deep data insights, and seamlessly integrate ticketing into their digital infrastructure.

With six offices worldwide and growing, we deliver a customizable, intuitive solution and industry-leading support that simplify even the most complex ticketing challenges – helping organizers deliver exceptional experiences and drive real growth.

Join us and build the future of live entertainment.

With over 10 million end users and usage quadrupling annually, our infrastructure now handles over 1 billion requests per month — and counting. Our API-first platform solves complex system challenges at scale — delivering performance, flexibility, and reliability for the world’s leading live entertainment brands.

This isn't just a maintenance role – it is a blank canvas to build, scale, and architect a state-of-the-art AppSec program from the ground up. We are currently operating at a fraction of our ultimate potential, which means you have an immense, blank-canvas opportunity to fundamentally shape our security culture, processes, and tooling across the entire global engineering organization. You will drive the entire AppSec lifecycle: from offensive red teaming and threat modeling to risk-based vulnerability management and pioneering a true shift-left culture. What Makes This Role Challenging and Engaging: High-Impact Technical Environment: You won't just follow blueprints; you will holistically influence a shift-left architecture across both application and platform layers. 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.

What you will need to succeed in this 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.

## About vivenu GmbH

## Company Overview
- **One-liner**: vivenu builds an API-first, white-label ticketing platform for live events, powering sports, culture, festivals, conferences, and universities while giving organizers full control over their brand, data, and fan relationships.
- **Entity Type**: Private (VC-backed scale-up, last known funding round: Series B)
- **Headquarters**: Düsseldorf, Germany (global HQ); additional offices in Frankfurt, New York City, Paris, and Tampa
- **Founded**: 2018
- **Founders**: Three co-founders, recognized by Forbes 30 Under 30 and named Executive of the Year (per the company's career page; names not detailed in verified public sources)

## Core Business
- **Primary industry**: Live-event ticketing technology (SaaS / API platform)
- **Target customers**: B2B — sports franchises, performing arts venues, festivals, universities, conference and cultural organizers; also serves tech leaders needing headless ticketing solutions
- **Mission**: To modernize the ticketing industry by providing the most flexible, open, and data-driven platform — one that lets organizers treat ticketing as a core revenue engine rather than a closed, restrictive system

## Products & Services
- **vivenu Platform**: White-label, fully customizable ticketing solution covering reserved seating, general admission, end-to-end checkout, and on-site payment terminals. Adapts to real-time workflows and keeps the organizer's brand front and center.
- **Headless Ticketing API & SDKs**: API-first architecture that lets developers integrate ticketing into any tool or build custom apps "with just a few lines of code" — the most flexible tier for tech-savvy organizers.
- **Analytics & Data Insights**: Real-time visitor behavior tracking and yield optimization, with reports of up to 23% online revenue increases.
- **Ecosystem Integrations**: Open integrations with CRMs, marketing clouds, analytics tools, and shop systems, enabling organizers to extend their stack without being locked into a closed vendor.
- **Dedicated Expert Support**: Designated support teams, digital consultants, and active customer communities bundled with platform adoption.

## Market Standing
- **Valuation/Market Cap**: Not disclosed (private company)
- **Key Metric**: $65.9M total funding (3 prior rounds; most recent round: $49.2M Series B led by Activant Capital and Hedosophia, announced November 2021). LinkedIn's third-party estimate lists annual revenue at ~$2.4M, though this is likely understated for a company of this scale.
- **Notable Investors/Partners**: Balderton Capital (Series A lead), Activant Capital (Series B lead), Hedosophia (Series B), redalpine (Seed lead)
- **Growth Signals**:
  - 1,000+ organizations powered across 50+ countries
  - 170+ employees (per company site); LinkedIn data estimates 158 employees, +25.5% YoY headcount growth
  - 800+ platform upgrades shipped in a single year during earlier scaling phase
  - Expanded from a small Frankfurt office to six global offices across Europe and the US (including New York, Paris, Tampa)
  - Named among the fastest-growing scale-ups across all categories by Sifted
  - Marquee clients include FC Schalke 04, the Grammy Awards, and Stanford University

## Competitive Advantages
- **API-first, white-label architecture**: Unlike legacy ticketing incumbents, vivenu lets organizers fully own their brand and user experience instead of forcing them into a white-labeled "storefront" that still belongs to the vendor.
- **Data ownership and open ecosystem**: Organizers keep their data and can plug in their preferred CRM, marketing cloud, and analytics stack — positioning vivenu as the "backbone" rather than the bottleneck of the stack.
- **Vertical breadth**: One platform serves sports, performing arts, festivals, conferences, and universities, creating diverse revenue streams across event categories.
- **Scale and reliability engineering**: Platform built for security, scale, and resilience across global markets, an essential requirement for enterprise live-event clients.
- **Strong corporate client base**: References like Schalke 04, the Grammys, and Stanford provide enterprise credibility and social proof.

## Strategic Focus
- **Continuous product investment**: The company commits its funding to technology development and platform evolution, shipping regular upgrades and expanding API/SDK capabilities.
- **Geographic expansion**: Strategic build-out of US operations (New York and Tampa offices) alongside European growth, with plans to deepen footprint across new markets and verticals.
- **Data-driven future**: Emphasis on clean, real-time data and analytics to help organizers optimize yield, understand audiences, and prepare for an AI-driven era of live entertainment.

## Why Work Here
- **Mission-driven impact**: Employees directly shape ticketing and fan experiences for global brands; the company highlights that work impacts "hundreds of clients and thousands of fans daily" and that millions of attendees will have lasting memories because of what the team builds.
- **Strong culture scores (from employee reviews, 23 reviews)**: 4.1/5 overall; career growth rated 4.2/5, culture 3.8/5, compensation 3.6/5, and work-life balance 3.4/5 — indicating a fast-paced, growth-oriented environment where career development is a standout.
- **Leadership pedigree**: Team guided by leaders from Google, Slack, and Salesforce; founders recognized by Forbes 30 Under 30 and named Executive of the Year.
- **Scale-up energy with financial stability**: Described as "scaling sustainably on a profitable, VC-backed foundation with true product-market fit," combining startup agility with long-term vision.
- **Flexible work model**: Remote Germany options available; six global offices across Düsseldorf, Frankfurt, New York, Paris, Tampa, and more foster a diverse, merit-driven, cross-border culture.
- **Learning culture**: "Daily learning and collective growth" is cited as a core ethos, reinforced by constant product iteration and a Sifted ranking among the fastest-growing scale-ups.
- **Active hiring**: Open roles span Sales, Customer Success, Marketing, and Product & Development, including senior security engineering and enterprise account executive positions — a signal of continued investment across functions.
