• Monitoring and Alerting: Monitor application performance and system health through observability tools (e.g., Prometheus, Grafana, ELK stack), proactively identifying and resolving issues to ensure high availability and rapid incident response.  

• Security and IAM: Implement security best practices, managing Identity and Access Management (IAM) policies across cloud environments. Utilize technologies such as OpenID Connect (OIDC), OAuth2, and SAML Single Sign-On (SSO) to ensure secure authentication and authorization across services.  

• Database Technologies: Manage and optimize database systems, including SQL databases and Mongo DB, ensuring high availability, performance tuning, and data security.  

• CI/CD Practices: Automate manual processes to enhance operational efficiency, employing Continuous Integration/Continuous Deployment (CI/CD) best practices for efficient code deployment.  

• Scripting Languages: Demonstrate proficient scripting skills in languages such as Java, TypeScript, and Python to automate tasks and manage configurations.  

• Load Balancing: Implement and maintain load balancing solutions to ensure optimal distribution of application traffic and high availability.  

• Collaboration with Development Teams: Collaborate with software engineering teams to design, develop, and maintain robust systems and solutions, including RESTful APIs, ensuring seamless integration across platforms.  

• Post-Mortem Analysis: Conduct comprehensive post-mortem analyses following incidents, identifying root causes and recommending improvements to enhance system reliability and performance.  

• Mentorship: Mentor and guide junior engineers, fostering a culture of knowledge sharing and continuous improvement within the engineering team.  

Skills and Experience:

• Bachelor’s degree in computer science, Engineering, or equivalent practical experience.  

• Proven work experience as a Site Reliability Engineer, DevOps Engineer, or in a similar role within a high-availability environment.  

• Strong experience with Azure with GCP and AWS cloud services, including a deep understanding of cloud architecture and services.  

• Expertise in Infrastructure as Code (IaC) using Terraform (HCL) and AWS CloudFormation.  

• Experience with AWS CDK for programmatic management of cloud resources, primarily using TypeScript.  

• Hands-on experience with container orchestration technologies, particularly Kubernetes.  

• Familiarity with version control systems (e.g., Git) and CI/CD pipelines for efficient code deployment.  

• Knowledge of monitoring and logging tools (e.g., Prometheus, Grafana, ELK stack) to ensure system observability.  

• Strong experience with SQL databases and AWS DynamoDB, focusing on performance tuning and optimization.  

• Proven ability to design and manage RESTful APIs, ensuring their reliability and scalability.  

• Excellent troubleshooting skills, with a proactive approach to resolving complex technical issues.  

• Strong communication and teamwork skills, enabling effective collaboration across cross-functional teams.  

• A curious and open-minded attitude, committed to challenging the status quo and exploring innovative solutions.  

It would be great if you: 

• Experience with networking concepts and troubleshooting in cloud environments.  

• Knowledge of security best practices in cloud computing.  

• Contributions to open-source projects or the creation of technical articles/blog posts to share knowledge with the community.  

• Familiarity with service mesh technologies.
