Description du poste

Streaming TV is no longer just a brand awareness channel. It's becoming a core part of the performance marketing mix, alongside search and social. 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 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 to reach 120 million+ households. And in August 2026, 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.

• 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.
