Backend Software Engineer - Performance

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.

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

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.

Move at Vibe pace

For candidates based in France, the pay range for this role is €127,000-€171,000. We will support relocation to Paris for great candidates.
