X Developer Platform – Forward Deployed Engineer, X API

xAI’s mission is to create AI systems that can accurately understand the universe and aid humanity in its pursuit of knowledge. Our team is small, highly motivated, and focused on engineering excellence. This organization is for individuals who appreciate challenging themselves and thrive on curiosity. We operate with a flat organizational structure. All employees are expected to be hands-on and to contribute directly to the company’s mission. Leadership is given to those who show initiative and consistently deliver excellence. Work ethic and strong prioritization skills are important. All employees are expected to have strong communication skills. They should be able to concisely and accurately share knowledge with their teammates.

X Developer Platform is responsible for the partner ecosystem of B2B and B2C developers that build solutions using X’s extensive API set. With more than 500 million active users and billions of posts per week, X offers robust, real-time and historical data, insights and engagement opportunities across a wide range of organizations and industries. Our API gives you the ability to learn from and engage with the conversation on X and we supply developers with the tools to further uncover, build on, and share the value of this conversation with the world.

Our mission broadly is to achieve the state of X, “The Everything App”, and be the clear digital townsquare of Earth. We make our ever-expanding universe of social media data available via our extensive API suite with consistent and reliable architecture so the world can realize the full potential of this amazing stream of information. Our team helps collect, process, enrich and deliver hundreds of billions of signals a day through the X API platform. Our products are highly available, scalable, optimized, respectful of X's user base, and truly essential for our customers who build their businesses on X data.
