Software Engineer - Ads Experience (소프트웨어 엔지니어)

About Moloco:

Moloco is an AI-native performance advertising company, bringing the power of AI advertising to the open internet. Founded in 2013 by machine learning engineers who had built AI advertising systems inside the world's largest technology companies, Moloco began from a shared mission: to build that same engine for the open internet.

Today, Moloco is one company with two businesses, built on the same compound AI system. Moloco Ads is our AI-native performance advertising platform, helping mobile app marketers acquire, retain, and re-engage high-value users across the open internet. Moloco Commerce Media is our AI-native retail media platform, enabling retailers and marketplaces to turn their platforms into thriving ad businesses. Both are powered by CARA (Compound Ad Recommendation Architecture), the AI system behind every Moloco product.

At Moloco, we bring together those who've already solved hard problems and those with the drive to. Here, we work on some of the complex problems in AI advertising, at a scale and level of sophistication very few companies can offer. Come build what's next.

About the role As a Software Engineer on the Ads Experience (AdEx) team, you will build and evolve core features, services, and workflows that power Moloco’s web-based campaign management portal, Moloco Ads Manager (our Ads Manager UI).

Contribute to analytics and reporting capabilities by integrating with data pipelines and helping deliver clear, actionable views of campaign performance and operational health. Improve the reliability, performance, and observability of the systems you build through strong engineering practices, including testing, metrics, logging, monitoring, and incident response. Contribute to raising the team’s engineering bar and support a collaborative culture of technical excellence and continuous improvement.
