• Continuously improve infrastructure reliability to minimise out-of-hours incidents

Preferred:

• Experience with Kubernetes in production environments

• Company-provided laptop (Mac or PC — your choice)
• Competitive salary (based on experience)
• Immediate start available

Important Requirements
