• Participate in architectural decisions and implement cloud infrastructure solutions using Azure and AWS services, ensuring high availability and scalability 

• Manage and optimize cloud resources to improve performance, cost efficiency, and security 

• Apply cloud-native best practices to secure and govern cloud environments, ensuring compliance with industry standards 

• Integrate advanced monitoring and alerting tools (e.g., Datadog, CloudWatch, Application Insights) to maintain system observability in multi-cloud environments 

Incident Management & Analysis 

• Lead incident response, conduct root cause analyses, and produce blameless postmortems to prevent future occurrences 

• Collaborate with development teams to integrate observability and performance metrics into the development lifecycle 

• Build and maintain executive-level and developer-centric dashboards to visualize key metrics 

Technical Expertise 

• Proven experience in running and maintaining production systems with expertise in triaging and solving incidents 

• Proficiency in automation and configuration management tools (e.g., Terraform, Ansible) 

• Expertise in cloud platforms, particularly Azure and AWS, and their associated tools 

• Strong programming skills, with a primary focus on Python, for developing automation scripts, creating custom tooling, and optimizing operational workflows 

• Experience with modern observability platforms such as Datadog 

• Strong network fundamentals with hands-on experience in Palo Alto next-generation firewalls, including configuration, monitoring, and troubleshooting in enterprise environments 

• Experience with Microsoft Identity solutions including Azure Active Directory (Entra ID), identity governance, and integration with enterprise authentication systems 

Skills & Experience 

• A solid foundation in system architecture, with a focus on scalability and reliability 

• Exceptional problem-solving skills and a data-driven mindset 

• Familiarity with CI/CD pipelines and tools like GitHub Actions and Azure DevOps 

Desirable Requirements 

• Experience with container orchestration tools such as Kubernetes 

• Knowledge of security best practices in cloud and hybrid environments 

• Experience with identity and access management solutions (e.g. Okta, Active Directory, Cyber Ark) including role-based access control and authentication protocols 

• Experience with network monitoring tools and infrastructure-as-code approaches to network configuration (e.g., Terraform for cloud networking, Ansible for network devices)
