• Contribute to a supportive on-call rotation and help solve issues with minimal out-of-hours disruptions.

Who You Are

• Familiar with Linux environments and capable of writing scripts and automating tasks.
• Comfortable juggling project work and BAU support while keeping an eye out for opportunities to improve systems.

Why Join?
