About the role
We’re looking for a Marketing Lead who thinks like a builder — a sharp storyteller with strong opinions about what good looks like, who’s as comfortable cutting a video as writing a launch post. You’ll work closely with the founders, Product, and GTM to make sure mobile publishers understand what we’ve built and why it matters. Your key responsibilities will be:
What they're looking for
- Exceptional writer: you write clearly and persuasively about complex technical subjects for different audiences, including engineers, publisher executives, and the broader industry. Your writing has a point of view
- Technical fluency: you’re comfortable explaining SDKs, auctions, and bidding dynamics, and you can hold your own with engineers when working out how to describe what they built
- Metrics-driven: you know which numbers matter at each stage, you instrument what you run, and you kill things that don’t work
- AI forward: you use AI tools pragmatically — to move faster and automate the busywork — and you have a real sense for what current models can and can’t do
- Adtech or mobile experience: you’ve marketed to mobile publishers or app developers, or worked at an ad network, exchange, SSP, or mediation platform, and you know the ecosystem’s players and pain points
- Developer marketing experience: you’ve marketed products where developers are the buyer or user — SDKs, APIs, infrastructure, developer platforms
More about this role
At CloudX we’re building a new supply-side advertising platform for mobile publishers. We’re convinced that an AI-native product will significantly advance the state of the art in mobile advertising. We recently raised a $30M Series A to bring this vision to life.
Our founding team previously built MoPub (acquired by Twitter for $350M) and MAX. Our platform combines verifiably fair auctions with an AI-native product experience to give publishers unprecedented control over their monetization strategy.
Our Marketing function is small, distributed, and remote — in fact, you’ll be it. We have a strong ownership culture and rely primarily on asynchronous, written communication to stay aligned. We work in close partnership with Product, Business Development, and Partner Success, and we ship fast and talk about it publicly: technical blog posts, launch threads on X, product videos, and conference appearances. Everyone has access to the latest AI tools, but rather than generating vibe-slop we use them pragmatically — to move faster, automate the busywork, and spend our time on the work that matters. As our first marketing hire, you’ll have significant influence over how CloudX shows up in...
