Company mission
To build AI systems that can help humanity understand the world better.
Role
Who you are
- Experience in LLM reinforcement learning, tool use, and agentic approaches
- Experience in real-world computer vision. For example, experience in visual/multimodal search and dealing with noisy visual data
- Strong engineering background with experience working with large-scale, modern backend services
- An attitude to just execute and solve problems. You’re willing to dive into new codebases you’ve not seen before if it means you can get stuff done faster
What the job involves
- Our team is pushing the frontier of multimodal intelligence through Grok Voice, the world’s smartest AI assistant that is able to listen, see, and respond to you in real time
- We actively learning to develop novel video understanding capabilities that solve user problems in both the physical and digital worlds
- We own the full-stack of post-training: from data curation to model training, deployment, and iterating end-to-end on the user experience
- Design, and implement methods to enhance video understanding, whether through developing new models, systems, or tools
- Improve data quality by curating robust datasets, building scalable data pipelines, and analyzing user interactions with models
- Develop and apply evaluation metrics to measure model performance and systematically identify and address failure modes
- Manage the complete experimental lifecycle: from designing experiments and training models to deployment and iterative refinement based on feedback and data
- Tech Stack:
- Python
- JAX / PyTorch
- Rust
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:
- One-on-one discussion & coding interviews (three meetings total)
- Project deep-dive: Present your past exceptional work and your vision with xAI to a small audience
- 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.
