Sr. Software Engineer, X Developer Platform

Job Description

Job Description

SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today, SpaceX is actively developing the technologies to make this possible, with the ultimate goal of making life multiplanetary and expanding consciousness to the stars.

SpaceXSI is building Super Intelligence to help humanity understand the universe. Our teams are building the full Super Intelligence stack: from our Colossus supercomputers, to Grok models, to our suite of applications, including Grok Bot, Grok Build, Grok Imagine, Grok Voice, and X. We're creating a powerful flywheel where more compute trains better models, better models power more useful products, and what we learn from people using those products shapes what we build next. SR. SOFTWARE ENGINEER, X DEVELOPER PLATFORM

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.

RESPONSIBILITIES:

• 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

BASIC QUALIFICATIONS:

• Bachelor's or master's degree in computer science
• 5+ years of industry experience working on commercial software application or services

PREFERRED SKILLS AND EXPERIENCE:
