xAI

xAI is an American artificial intelligence company founded by Elon Musk in 2023 with the stated goal of building models that help humans understand the universe. It develops the Grok family of large language models, distributes them through a consumer assistant, a developer API and deep integration with the X social platform, and adds image and video generation through Grok Imagine. The company runs its own Colossus supercomputer clusters in Memphis, Tennessee, is headquartered in Palo Alto, California, and merged with X Corp in 2025 to combine model development with a large consumer distribution channel.

SpaceXAI’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.

  • Dive into performance issues and work with customers and deliver solutions to cater to customers’ latency, availability and data durability requirements.
  • Lead and drive incident responses and recovery with your peers. Review and contribute to incident postmortems and hold a high bar for the same.
  • Work in a collaborative environment and uplevel your peers by doing mentoring, code and design reviews.
  • Be open to develop new skills and learn on the job as we navigate new technology spaces.
  • Ground your decisions with data and reasoning and adapt to new information to make informed choices.

BASIC QUALIFICATIONS:

  • Have at least 7 years of experience in software development, plus 2+ years building storage systems or databases.
