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.

All employees are expected to have strong communication skills. They should be able to concisely and accurately share knowledge with their teammates.
X Ads is one of the highest-leverage product areas at X. You’ll work on systems that operate at massive scale, directly affect the business, and are being rebuilt with modern infrastructure and AI at the center. This is an opportunity to join a small, fast-moving team where early-career engineers can take on real ownership, learn from strong engineers, and ship products that matter.
We’re looking for high-slope software engineers who want to help rebuild and transform the X Ads Platform using xAI’s infrastructure and AI stack.
This role is a great fit for engineers who are early in their careers but learn quickly, ship fast, and want to work on products and systems that operate at massive scale. You do not need to have deep ads experience already, but you should be excited to learn how large-scale advertising systems work and how AI can make ads more relevant, useful, and effective.
You’ll work across product, backend systems, infrastructure, and AI-powered features that directly impact the majority of X’s revenue.
You do not need to know every technology listed below. We care more about strong fundamentals, learning speed, and ability to ship.
$150,000 - $350,000 USD
