• Strong analytical and problem-solving skills in complex systems
• Ability to support time-sensitive, high-availability environments
• Clear communication skills for working across technical and non-technical teams

We don’t expect candidates to have deep expertise in all areas, but strong fundamentals and the ability to learn quickly are essential.

Preferred Qualifications
