Company mission
To build AI systems that can help humanity understand the world better.
Role
Who you are
- Worked on system optimizations for model serving, such as batching, caching, load balancing, and parallelism
- Worked on low-level optimizations for inference, such as GPU kernels and code generation
- Worked on algorithmic optimizations for inference, such as quantization, distillation, and speculative decoding, and low-precision numerics
- Worked on large-scale inference engines or reinforcement learning frameworks
- Worked on large-scale, high-concurrent production serving
- Worked on testing, benchmarking, and reliability of inference services
What the job involves
- Optimizing the latency and throughput of model inference
- Building reliable production serving systems to serve millions of users
- Accelerating research on scaling test-time compute
- Model-hardware co-design for next-generation architectures
Application process
- After submitting your application, the team reviews your CV and statement of exceptional work
- If your application passes this stage, you will be invited to a 15-minute interview (“phone interview”) during which a member of our team will ask some basic questions
- If you clear the initial phone interview, you will enter the main process, which consists of four technical interviews:
- Coding assessment in a language of your choice
- Systems hands-on: Demonstrate practical skills in a live problem-solving session
- Project deep-dive: Present your past exceptional work to a small audience
- Meet and greet with the wider team
- Our goal is to finish the main process within one week
- We don’t rely on recruiters for assessments. Every application is reviewed by a member of our technical team
- All interviews will be conducted via Google Meet
Our take
xAI is Elon Musk's venture into the world of artificial intelligence, and like all things Musk, it's going big. Its setting out to build AI that helps humanity understand the universe and its 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, xAI is certainly pushing towards artificial general intelligence at serious scale.
Like all bold ventures, xAI has faced its share of controversy, from questions about regulation to the overlap across Musk's businesses. But fans are still seeing the bigger picture: an interconnected tech ecosystem where AI, social media, and space exploration feed into one another.
Recently, the company made headlines 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.
