• Perform system patching, software updates, and security hardening to maintain infrastructure integrity.

• Develop and maintain technical documentation, operational procedures, and infrastructure guidelines.

• Identify opportunities to improve cloud cost efficiency through resource rightsizing, reserved instances, and autoscaling configurations.

• Automate recurring administrative tasks using Bash, Python, or PowerShell, along with Infrastructure as Code (IaC) tools such as Terraform, CloudFormation, and ARM/Bicep.

Performance Benchmarking

• Plan and conduct performance tests across cloud compute, storage, and network resources.

• Develop reusable benchmarking scripts and automated testing pipelines, ensuring testing procedures are consistently documented.

• Evaluate benchmarking results and prepare reports outlining findings, performance gaps, and recommended improvements.

• Monitor performance metrics over time to identify unusual behavior, degradation, or regressions.

• Work with engineering teams to apply performance findings to infrastructure planning and technical decisions.

Required Qualifications

• At least 5 years of experience managing and administering cloud infrastructure in production environments.

• Hands-on experience with at least two of the following platforms: AWS, Microsoft Azure, and Google Cloud Platform (GCP). Experience across all three is strongly preferred.

• Strong proficiency in Linux server administration.

• Practical experience with scripting and automation using Bash, Python, or PowerShell.

• Familiarity with performance benchmarking and testing tools, such as sysbench, fio, iperf, Geekbench, and cloud-native monitoring utilities.

• Understanding of cloud networking, Identity and Access Management (IAM), and cloud security fundamentals.

• Strong analytical and problem-solving abilities.

• Ability to interpret technical results and communicate findings and recommendations clearly to management.

Bonus Qualifications

• Cloud certifications (AWS Certified SysOps Administrator, Azure Administrator

• Associate, Google Cloud Professional Cloud Architect, etc.)

• Experience with Infrastructure-as-Code (Terraform, CloudFormation, ARM templates)

• Familiarity with monitoring/observability platforms (CloudWatch, Azure Monitor,

• Google Cloud Operations, Datadog, Grafana)

• Experience with CI/CD pipelines and DevOps practices

Working Conditions

• 100% remote work

• Night shift schedule during the initial months; schedule may become more flexible after the probationary period.
