About Moloco:

Moloco builds some of the most powerful AI advertising solutions in the world. Our name—short for "machine learning company"—reflects our core mission: democratizing access to the advanced AI that has historically been reserved for tech giants. Led by machine learning pioneers who built some of the most successful ad systems at Google, including YouTube's monetization engine and key search advertising technologies, we're transforming how businesses grow and compete in the digital economy.

Built with AI from day one, Moloco’s planet-scale machine learning platform powers a suite of solutions for advertising growth and monetization. Moloco Ads is an AI-powered platform that delivers real business outcomes for mobile app marketers through performance-based user acquisition.

Moloco is headquartered in Silicon Valley, with offices in Seattle, New York, San Francisco, Seoul, Beijing, Singapore, Gurgaon, Tokyo, Shanghai, London, Tel Aviv, and Berlin.

Moloco is a truly rewarding place to work and in an exciting period of growth, which you could be a part of. Join us today and apply now!

The Impact You'll Be Contributing to Moloco:

You will be building Moloco's mobile Ads SDK that enables publishers (app developers) to monetize their mobile applications. Your work will make a direct impact on Moloco's revenue. This role is highly cross-functional, spanning client SDK, backend integrations, and cross-platform tooling. You may work directly with external customers and collaborate closely with our engineering teams.

The Opportunity:

• Design, architect, and build a state-of-the-art Ads SDK for Moloco's supported platforms.

• Keep up to date with the latest iOS updates, and maintain the SDK.

• Follow and lead technology evolution and requirements across prominent app platforms, contributing to shared logic and architecture decisions that span iOS and Android.

• Partner with backend and infrastructure teams on the APIs, telemetry, and services that power the SDK end-to-end.

• Help customers with SDK integrations in various ways, including maintaining customer-facing SDK documentation.

• Help grow our team by providing valuable feedback and by mentoring junior engineers.

• Work with cross-platform teams located across our global offices including Seattle, Seoul, London, Beijing, and San Francisco to come up with new features and functionality for our customers.

How Do I Know if the Role is Right For Me?

• Bachelor's degree or above in Computer Science or an equivalent technical degree

• 5+ years of experience as a software engineer, including strong experience with iOS

• Proficiency in Swift and/or Objective oriented programming

• Expert-level understanding of multithreading and networking

• Understanding of the internals of iOS, compilers, and optimization for lower-power devices

• Full-stack curiosity — comfortable working across client, server, and tooling layers, not just native UI code

• Experience with agile methodologies and high-level design principles

• A passion for mobile platforms, and staying up-to-date with the latest platform developments

Preferred Skills:

• Experience with Android development (Kotlin/Java) or cross-platform frameworks (React Native, Flutter, Kotlin Multiplatform) — dual iOS/Android fluency is a strong plus

• Experience building and distributing Cocoapods, Carthage, and/or Swift Package Manager libraries

• Experience publishing apps to the App Store and/or Google Play

• Experience with MRAID and/or VAST

• Experience building and distributing React Native and/or Unity plugins

• Backend or full-stack experience is a plus
