Senior Software Engineer, Supply

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. Your team You will join the Supply team, which owns Vibe's inventory: the publishers we partner with, the deals we run, and the catalog of apps, channels and shows our advertisers care about. Shows are the reason people turn on their TV. Advertisers don't just want impressions: they want to show up next to the right shows, live sports and premium channels. Supply brings that content to Vibe through direct publisher partnerships, curated deals and sponsorships. It makes it easy to find, understand and buy, through real-time bidding, or any technology the publisher uses. Premium publishers care as much about which ads run on their shows as about who buys them, and great creatives are what earn us access. The team brings together partnerships, operations, and product. You will work closely with the DSP team, which runs the bidding infrastructure, and the Performance team, which decides how to value each opportunity, as well as with publisher partners directly. Your mission As a Senior Software Engineer on Supply, you will build the systems that let Vibe grow, operate, and trust its inventory. You will turn publisher partnerships into live, healthy supply, and give the business and our partners the tools to manage it at scale. What you will do Publisher integrations Build and improve publisher integrations end-to-end, from onboarding a new partner to supporting new ad formats and sponsorship offers. Implement measurement requirements with publishers and the DSP team (e.g. UID2, publisher IDs) so the bidder sees richer inventory. Own integration health: detect broken or degraded supply before it costs us spend. Deals & catalog Build the services behind deal setup, catalog management, and price configuration, in partnership with DSP on the deal API. Automate the routine work of the Supply team (new deals, stale-supply cleanup, troubleshooting) so it scales with the number of partners, and with Vibe. Enrich the catalog with content data (shows, genres, live events, channels) so advertisers can find what they are looking for, and even enjoy looking for it. Supply tooling & publisher platform Build real-time monitoring, alerting, and analytics on supply volume, quality, and spend. Build publisher-facing features: reporting, insights, and self-serve catalog tools. What we're looking for 5+ years of experience as a software engineer building and operating backend systems in production. Strong programming skills (Go, Python and/or Rust), with real engineering discipline: testing, code review, CI/CD, maintainable design. Han
