- Experience with the latest CPU and GPU technologies

- Proficiency in shell scripting (bash), working knowledge of Python, and familiarity with Ansible or similar configuration management tools

- Proven hands-on experience building servers from components, diagnosing hardware failures, and working with vendors

- Excellent documentation and communication skills
