À propos de ce poste Staff or Senior Machine Learning Engineer - Identity & Audience chez Vibe
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
Data isn't a support function at Vibe, it's the fuel. Every decision about which ad reaches which household, and when, runs on it. You'll join the Data Platform team and specialize in identity, turning billions of raw events into coherent, usable entities that power targeting, measurement, and the training sets Vibe's models learn from. You'll report to the Head of Data Platform. This role exists because identity resolution at Vibe's scale is a hard, unsolved problem, and the team needs someone who can build models that catch the right signal across petabytes of events. You'll get direct, measurable impact: your work decides which ad reaches whom and whether it worked, not a metric buried in a research paper. You'll shape the roadmap for a system every team at Vibe depends on, and work on a problem that only gets more interesting as CTV scales.
What You'll Do
Identity Stack Ownership
Research and build algorithms that resolve coherent entities, like users and households, from billions of events
Turn machine learning, clustering, and statistical approaches into scalable, production-ready systems
Lead projects end-to-end, from stakeholder requirements through research, implementation, and post-launch iteration
Build platform-level identity-resolution tooling so every team can resolve identity behind their own events
Design for scale from the start; treat unscalable local tests as unfinished work
Cross-Team Partnership
Help shape and execute the roadmap for Vibe's identity stack
Surface tradeoffs, risks, and decisions to stakeholders without burying them in implementation detail
Translate ambiguous requests from Product, Sales, ML, and Finance into concrete deliverables
Collaborate with other ML engineers on MLOps problems
What You Need
5+ years of experience as an ML engineer or data scientist building and operating production services
Experience operating at data scale, using tools like Dagster, Spark, or Iceberg
Familiarity with MLOps tooling and practices
A track record of leading technical projects end-to-end, from ambiguous requirements to shipped systems
Strong cross-functional communication skills, including adjusting detail level for your audience and pushing back constructively
Judgment about when to invest in abstraction and when to keep things simple
Nice to Haves
Experience in streaming TV advertising or programmatic advertising
