Public Cloud Administrator (Entry Level)

About the role

Marsh is looking for an entry-level Public Cloud Administrator to manage, maintain and optimise its cloud infrastructure across Amazon Web Services (AWS), Microsoft Azure and Oracle Cloud Infrastructure (OCI). The role suits a recent college graduate with foundational cloud knowledge who wants to grow technical skills in a supportive, team-oriented environment. It is a hybrid position with at least three days a week in the office.

Key responsibilities

• Deploy, configure and manage cloud resources (compute, storage, networking, databases) across AWS, Azure and OCI, while supporting existing on-prem Nutanix and VMware Horizon VDI environments.
• Monitor cloud health, performance and utilisation; respond to routine alerts, escalate incidents and take part in a rotating weekly on-call schedule.
• Configure and secure storage (e.g. Amazon S3) with encryption, versioning, lifecycle rules and bucket policies, implement IAM basics and follow security and compliance controls.
• Support migration and upgrade tasks with senior engineers and help with application deployments and integrations with development, operations and security teams.
• Contribute to cost-optimisation and performance tuning, and create and maintain documentation of configurations and procedures.

Required profile

• Bachelor's degree in Computer Science, Information Technology or a related field, or 1-3 years of relevant practical experience.
• Strong foundation in cloud concepts (compute, storage, networking, IAM) and physical data centre fundamentals (server hardware, storage, networking).
• Good verbal and written communication skills and ability to work with technical and non-technical stakeholders.

Required skills

• Working knowledge of cloud networking (VPCs/VNETs, subnets, security groups, firewalls, DNS) and comfort with Windows and Linux servers.
• Basic scripting (Python, PowerShell or Shell) and exposure to Infrastructure-as-Code.
• Nice to have: internship or cloud platform experience, entry-level cloud certification (e.g. AWS Certified Cloud Practitioner), familiarity with monitoring and logging tools such as CloudWatch, and interest in further certification.
