About our Partner
Our partner is an early-stage AI-native advertising platform built for regulated sportsbooks and casino operators in the United States. They emerged from agency work with major US sports betting and gaming brands, where they sat close enough to the marketing, media buying, and compliance workflows of these companies to see the gap clearly: most advertisers test enormous volumes of creative but don't consistently learn from it. Their bet is to convert that operational knowledge into software, a Slack-first, AI-native operating layer for ads that monitors compliance, generates creative at scale, learns from performance,



and eventually makes safe campaign decisions across Meta, Snapchat, TikTok, and Apple Ads.
The Role
This is a Staff Full Stack Engineer role focused on backend architecture, where the engineer will be the second core member of the founding team. AI workflows, LLM orchestration, and creative generation pipelines are central to the work. The domain involves regulated external API writes to ad platforms, meaning errors carry real financial and legal consequences. Strong candidates come from ad tech or similar compliance sensitive environments and know how to build safe, auditable systems by default.
What We're Looking For
This role calls for a senior backend engineer who takes full ownership of complex systems end to end. The idóneo candidate builds with AI as a core part of the architecture, having shipped production systems using LLMs and media generation APIs, and knows when to use agentic approaches versu
