It’s becoming a core part of the performance marketing mix, alongside search and social. [Vibe.co](http://Vibe.co) is building the platform that makes TV work like the rest of the acquisition stack: targeted, measurable, and optimized for results. [Vibe.co](http://Vibe.co) is an Audience First Streaming TV Advertising platform that gives marketers the tools to reach the right audiences, optimize campaigns in real time, and understand what’s actually driving business outcomes. With hyper-targeted segmentation, AI-powered recommendations, real-time optimization, and incrementality measurement, Vibe brings the precision and accountability of digital advertising to the biggest screen in the house. Today, more than 12,000 brands use [Vibe.co](http://Vibe.co) to reach 120 million+ households. And in August 2026, [Vibe.co](http://Vibe.co) became a Walmart company, opening up a new chapter for the business and the industry. With Walmart’s first-party data and purchase signals now part of the Vibe platform, advertisers can connect TV advertising to real-world transactions and measure the impact of CTV with a level of precision previously associated with platforms like Google and Meta. This is a unique moment to join Vibe. With Walmart’s scale, data, and reach behind us, we’re building the next generation of TV advertising and creating a more measurable, performance-driven future for the channel. ## About the Role You'll be Vibe's founding security hire. Security has been part of how we build since day one and we're already SOC 2 Type 2 compliant, but nobody has owned it full-time. Ad spend and headcount have both roughly doubled every year since 2022, enterprise partnerships keep expanding, and the more visible Vibe becomes, the more scrutiny comes with it. Now it needs an owner. You'll define the risk model, set the roadmap, decide what we harden and what we accept, and turn policies into running procedures in code on the paths engineers and AI already use. That work happens in a cloud native ecosystem across AWS and GCP, with most of our services running on Kubernetes, everything as code and a GitOps deployment model. Reporting to our, Head of Infrastructure, and joining a lean six-person Infrastructure and IT team. You won't do it alone, but you'll be the main contributor, and the person every team turns to on security. Since we joined forces with Walmart, you'll also coordinate directly with their cloud security teams. ## What You'll Do Risk & Governance - Map Vibe's risk model across every major system. - Set the security roadmap with clear priorities. Security Engineering - Pave the road with guardrails and secure defaults enforced across the engineering tool set. - Ship the golden paths so the safe way is the easy one. - Harden security across our cloud native ecosystem (AWS and GCP) and third-party providers. - Own access management from onboarding to offboarding, and get it to the point where it runs without you. Detection & Response - Prioritize vulnerability findings by real exposure, assign them to the team that owns the code, and follow remediation through to closure. - Own security incident response from detection through resolution. - Turn manual processes into pipelines that run on their own. - Launch and run Vibe's private bug bounty program. Trust & Compliance - Own SOC 2 compliance end to end and maintain current certification. - Drive Vibe's future compliance initiatives and requirements. - Define Vibe's security posture and make it self-serve so enterprise deals clear security without routing through you. Security Culture - Set clear, practical rules for safe AI use, built into the tools themselves, covering both the AI we ship in our products and the AI our teams work with every day. - Run security awareness training and measure behavior changes so the whole company raises its bar. ## What You Need - Built a security function as a company's first security hire. - Write code comfortably and bring deep cloud-native security experience. - Managed a compliance framework at scale, such as SOC 2, ISO 27001 or HIPAA. - Managed AI security risk hands on, both in what a company ships with AI and in how its employees use it day to day. Nice to Haves - Ran a private bug bounty program. - Ad tech security background, including exposure to US privacy law (CCPA/CPRA, VPPA) in a data-heavy environment. - Navigated security through a company acquisition. ## Our Values At Vibe, we run on three values: Impact, Ambition, and Urgency. We tie every goal to a real business outcome, think 10x rather than settling for good enough, and move daily rather than waiting for perfect conditions. You'll thrive here if you own outcomes without needing direction, default to action, and hold yourself to results, not effort. This is a high-performance environment with high-performance rewards: you'll work alongside people who push you, with real ownership over hard problems in a market that's moving fast. If that sounds like the best version of your career, we want to meet you. ## What We Offer For candidates in France, the pay range for this role is €115,000-€175,000. At Vibe, we want you to build something, own something, and grow fast. Here's how we back that up: - Variable pay — Based on real Vibe business goals. - Hybrid flexibility — We're in the Heart of Paris and our team is in 3x a week! - Health insurance — Full coverage via Alan. - Meal vouchers — Via Swile. - Annual offsite — The whole team, once a year, somewhere worth the trip. - Tech Syncs — Engineering and Product meet in person at least quarterly, worldwide.

We’ll share more context on the role and team, and learn more about your background and what you’re looking for. - Hiring Manager Interview — 45 minutes. Meet with the person you’d work with directly and dive deeper into your experience, technical background, and approach to the role. - Technical Assessment — 90 minutes.
