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 Performance team the engineers who own advertiser outcomes at Vibe. Bidding, pacing, and the prediction stack that drives both. You'll report to Clément Schiano, Engineering Manager for Performance.
This role exists because our roadmap is clear and the bottleneck is execution. We have a knowledge concentration problem too: critical expertise sits with one person, which creates fragility. We need someone who can absorb, challenge, and extend that knowledge not just ship tickets.
Three reasons someone great would want this job:
CTV performance advertising is still being invented. The auction dynamics, identity graph, and feedback loops are nothing like display or search. There's no playbook to copy you'd be writing it.
You own the full decision loop. From prediction to bid price to pacing, on a product real advertisers depend on today. Your judgment shapes the direction. You'll see the impact in the numbers within weeks.
The timing is right. Past "does this work?" and into "how fast can we scale this?" Early enough to shape the architecture. Late enough that you're not building on sand.
Own the pacer and bidder
Go deep on the bidder and pacer stack map it end-to-end and identify at least one fragility worth owning on day one
Propose improvements to the bidder or pacer autonomously from problem definition through to design proposal
Ship measurable improvements to CPx, pacing accuracy, or win rate within your first three months
Raise the team's ceiling
Distribute critical system knowledge: make the team faster and less dependent on any single person
Challenge existing designs, including inherited ones, and push for cleaner solutions
Deepen expertise in the theoretical foundations (probabilistic modelling, PID control theory) powering our approaches
Move at Vibe pace
Use AI tooling as a genuine force multiplier (not a crutch, not a checkbox)
Iterate in production, not in your head, we - ship, measure and adjust
Shipped backend systems in a strongly typed language C++, Rust, Go, Scala, Java, or equivalent at production scale
Debugged distributed systems under real traffic: latency issues, consistency failures, the works
Worked inside a DSP, SSP, or bidder: you understand auction mechanics from the inside
Built or tuned pacing algorithms or PID controllers theory and implementation, not just awareness
Solid grounding in probabilistic reasoning and statistical modelling you think in distributions, not just averages
Nice to Haves
Experience in a scale-up environment you know what fast and resource-constrained actually feels like
ML systems in production: feature pipelines, model serving (not just training notebooks)
Real-time data pipelines and low-latency architectures at scale
Redis, Kafka, or equivalent under meaningful load
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.
