Required Qualifications

• 5+ years of hands-on experience managing enterprise infrastructure in production environments.
• Proven experience working in mission-critical, high-availability environments - financial services or similarly regulated sectors a strong plus.
• Strong practical experience with AWS infrastructure: EC2, VPC, IAM, S3, RDS, Transit Gateway, Direct Connect, CloudWatch you have built and fixed things there, not just read about them.
• Solid working knowledge of Azure and familiarity with GCP.

• Working knowledge of networking: VLANs, firewalls, load balancers, DNS, VPN, and hybrid connectivity.
