Senior Site Reliability Engineer

At Vibe.co, we're reimagining how brands reach audiences in the age of streaming. We believe streaming TV is no longer just a brand awareness play, it's the next great performance marketing channel. We're building the infrastructure to unlock this $100B opportunity.

Vibe.co provides an Audience First Streaming TV Advertising solution for marketers to unlock TV as a growth channel. Our all-in-one solution combines hyper-targeted audience segmentation, AI-powered insights and recommendations, real-time campaign optimization, and incrementality measurement, giving brands of all sizes the precision and transparency they've come to expect from social and search, but on TV.

Trusted by over 10,000 brands, Vibe.co reaches more than 120 million households across 500+ apps and channels, delivering an average 250% return on ad spend and 20% sales lift. The company hit a $100 million revenue run rate in under two years, ranking among the ten fastest software companies to reach that milestone.

Vibe.co's investors include Hedosophia (an early backer of Spotify, Uber, and Airbnb), Elaia, Singular, QuantumLight (Revolut CEO Nik Storonsky's fund), and Illusian (Supercell CEO Ilkka Paananen's fund), as well as angel investors including Carolyn Everson, board member of The Walt Disney Company and Coca-Cola. Nirav Tolia, CEO of Nextdoor, sits on the company's board of directors.

Founded in 2022, Vibe.co is widely recognized as the category-defining platform in streaming TV advertising, bringing the power of Meta and Google-style performance marketing to the fastest-growing segment in media.

You'll join the Infra Platform team, the backbone of everything engineering at Vibe. We own hosting, provisioning, observability, CI/CD, internal tooling, security, and compliance. Every product and platform team runs on what we build.

You’ll report to our Lead Platform Engineer, and together with the team, you’ll help shape the technical direction and uphold the infrastructure standards the whole company relies on.

This role exists because our platform is growing fast, and more than 60 engineers depend on it every day. We’re looking for someone who can take on real ownership and help shape how it scales. You’ll work on infrastructure handling more than 600k QPS, latency targets under 10ms, and over 5 PB of storage. Just as importantly, you’ll be someone other engineers turn to when the hard problems show up, which gives this role real influence across the company.

• Fluency in at least one systems-oriented language, ideally Go or Python, with the ability to build automation and operational tooling

• Deep experience with CI/CD, observability, and production operations, including metrics, logs, traces, alerting, and debugging live systems

• Comfortable leading incident response, improving service reliability, and driving root cause resolution

• Able to support product and engineering teams as a trusted infrastructure partner

• Uses AI effectively in day-to-day engineering, with strong judgment about when it adds leverage and when deeper manual work and critical thinking matter more.

• Built internal developer tooling, service scaffolding, unified observability portals, self-serve provisioning

• Hands-on experience with SOC2 compliance, you've helped a team get there, not just read about it

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.
