System Administration and Logging

• Analyze IIS logs and Windows Event Logs to identify issues or anomalies.

• Participate in system audits and contribute to compliance efforts.

Deployment and Release Management

• Support and execute application source code deployments in production and non-production environments.

• Collaborate with developers to ensure deployment readiness and rollback strategies.

Requirements

Must-Have:

• Solid understanding of cloud infrastructure and services, particularly within the Microsoft Azure ecosystem.

• Experience managing basic network infrastructure including firewalls, CDNs, and load balancers.

• Hands-on experience with virtual machines, Azure monitoring tools, and system scaling.

• Strong cybersecurity knowledge with direct experience conducting VAPT and secure code reviews.

• Familiarity with application deployment pipelines and configuration management.

Preferred:

• Certifications such as Microsoft Certified: Azure Administrator Associate or CompTIA Security+.

• Experience with tools like Nessus, Burp Suite, SonarQube, or similar.

• Background in DevOps practices and Infrastructure as Code (e.g., Terraform or ARM templates).

What We Offer

• Opportunity to work on cloud-native applications hosted entirely on Azure.

• A collaborative and inclusive team environment.

• Professional growth opportunities in both cloud infrastructure and cybersecurity domains.

• Competitive salary and benefits.
