Senior AWS Cloud Administrator

We are seeking a highly experienced and self-motivated Senior AWS Cloud Administrator to join a prominent Randstad client in the Washington, D.C. area.

Key Responsibilities

• Install, configure, administrate, manage, and support core AWS resources, including EC2, S3, RDS, and VPC.
• Manage and support end-to-end AWS cloud infrastructure solutions, demonstrating a strong understanding of cloud components (server, storage, network, security, data, and applications).
• Perform full-stack installation, configuration, and management of both Windows and RHEL servers deployed in the cloud environment.
• Proactively apply patches, configuration changes, and security updates to address identified vulnerabilities on Windows and RHEL servers.
• Take ownership of complex technical issues, using sound judgment and a sense of urgency to resolve incidents within defined service levels.
