Role
Who you are
- MS or BS in Computer Science
- 5+ years of industry experience working on commercial software application or services
- Distributed Systems experience (Kafka experience is a plus)
- Experience working with RPC frameworks and microservices

What the job involves
- The X Developer Platform team owns the partner ecosystem that connects X with B2B and B2C developers around the world
- X reaches more than 500 million active users who produce billions of posts every week, and that activity generates signals and capabilities that go far beyond a conversation to listen to: real-time knowledge of what is happening in the world, rich media, commerce, communities, and the connective tissue between people, businesses, and now agents
- Our job is to make that value available to developers as the everything API, so that anyone can build products on top of X
- Our mission is to help achieve the X Everything app and make X the clear digital townsquare of Earth. We do this by making X data and functionality available through a consistent and reliable API suite, so that developers and the emerging world of agents can realize its full potential. Behind the scenes we collect, process, enrich, and deliver hundreds of billions of signals a day
- The products we build are highly available, scalable, optimized, respectful of X's user base, and essential to the customers who depend on them. We work closely with our Product and Business counterparts and directly with customers to shape what we build next
- Collaborate with engineering, product leadership, business leadership, and engineers across the company
- Maintain and improve the systems that serve our existing customers while designing and shipping new products that expand what the platform can do
- Design clean, reliable, well-abstracted solutions to problems of scale, correctness, and developer experience
- Help shape the architecture of the platform as it grows to serve new categories of consumers, including agents and automated systems
- X Developer API Products Include:
- Real-time delivery of public posts and events, filtered and enriched to match each customer's use case
- Search and retrieval across the full historical archive of public content on X
- APIs for creating, publishing, and managing content and interactions programmatically
- Engagement, audience, and performance data that powers analytics and measurement products
- Enrichment layers that add context, structure, and relevance signals to raw platform data
- Interfaces designed for programmatic consumers, enabling agents and automated systems to read from and act on the platform safely
- Developer tooling, documentation, and self-serve onboarding that make the platform easy to adopt and integrate
Our take
SpaceXAI, formerly XAI, is Elon Musk's venture into the world of artificial intelligence, and like all things Musk, it's going big. It's setting out to build AI that helps humanity understand the universe, and it's starting with Grok, its conversational AI chatbot already integrated into X (formerly Twitter). With access to real-time data and a powerful ecosystem of Musk-led companies, SpaceXAI is certainly pushing towards artificial general intelligence at serious scale.
Like all bold ventures, SpaceXAI has faced its share of controversy, from questions about regulation to the overlap across Musk's businesses (most recently, XAI became a subsidiary of the Musk-owned SpaceX). But fans are still seeing the bigger picture: an interconnected tech ecosystem where AI, social media, and space exploration feed into one another.
The company made headlines in 2024 with its massive "Colossus" supercomputer project, powered by tens of thousands of Nvidia GPUs. While the data center's temporary power setup has faced environmental scrutiny, the scale of ambition is certainly undeniable. From launching tap-to-pay features on X to building one of the most powerful AI training systems on Earth, xAI is moving fast.
