• Enhance the reliability, performance, and cost-effectiveness of xAI’s storage infrastructure to support large-scale AI research workloads.
• Collaborate closely with researchers to understand their data use cases and tailor storage solutions to meet their needs.
• Implement robust security measures to safeguard critical datasets, ensuring data integrity and confidentiality.

Ideal Experience

You’d be an exceptional candidate if you possess some (or all) of the following:

• Writing scalable, high-performance code in Rust or Go for storage-related applications or tooling.
• Managing storage infrastructure with IaC tools like Pulumi, Terraform, or Ansible.
• Past experience working with storage vendors facilitating partnership alignment, and integrating their tooling within xAI’s Infrastructure.
• Familiarity with Kubernetes storage primitives (e.g., Persistent Volumes, CSI drivers) and integrating storage with containerized workloads.
• Bonus: Experience with AI/ML data pipelines, including handling large datasets for training and inference.

Interview 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 45 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 Python, Golang, or Rust
• Systems hands-on: Demonstrate practical skills in a live problem-solving session.
• Coding assessment or system design discussion based on the candidate's background.
• Project deep-dive: Present your past exceptional work to a small audience.

Every application is reviewed by a member of our technical team. All interviews will be conducted via Google Meet.
